Scar 18 CPU & GPU Liquid Metal Repaste - This is why you have HIGH TEMPS - How to apply Liquid Metal 

For the people who will attempt this: After you do this, the first boot will take like 1-2 min. Your keyboard will continue to flash and eventually you will hear the asus boot logo then screen boots up. Be sure to plug in the charger! Thanks @noyjr9492

This is happening to my strix scar 16 as well. Thanks a lot for making the guide, it feels a lot better going into a repaste seeing another person do it first

Timestamps: 4:45 - Laptop Cover taken apart 12:20 - Heatsink removed 13:56 - The JOKE from ASUS 14:33 - Repasting (this is long - taking my time with it) 33:05 - Repasting almost done 35:50 - How the heatsink should look 36:17 - Reapplying the heatsink 43:09 - The results - Cinebench R23 (previous score that I had 26.6k)

It is indeed! it is just as you explain in the video, my friend. I opened my g18 and I found exactly the same, the performance increased considerably. previously 27180 cinebench, then 34651. thank you very much for your video!

Congratulations on the video. About 5 months ago I was searching like crazy all over the Internet for people like you and finally I found them. You have no idea how hard I searched for a video like yours, so congratulations once again. Now I want to tell you that liquid metal actually works a miracle on notebooks. I have a Lenovo Legion 5i gen 5, the model with i7-10750h and RTX2060, with liquid metal it is as strong as the Legion with an RTX4060. It's unbelievable, when I say this people don't believe it because it's too good to be true. I had to remove the liquid metal because, as my notebook did not come with liquid metal from the factory, it is not prepared to walk around with something that could run all over the motherboard, thus ruining the notebook. That's why I was looking for videos like yours, to see how manufacturers applied this solution and finally I managed to see it. A simple foam to contain the liquid metal, a layer of nickel and no thermal pads. I'm now going to build this solution for my Lenovo Legion 5i and transform it into a monster that goes head to head with today's models.

I just got the time today to reapply the liquid metal. And when i say its bad its realllly bad. My chip barely had any liquid metal and everything spilled on the side from asus.. the NVIDIA marked on my heat sink as it gets too hot when gaming and with barely any liquid metal on it. I suggest everyone having bad temps to repaste theirs while its not too late and while there are no permanent damages.

Thank you for this video. After ASUS RMA'd my SCAR 16 4080 with a replacement motherboard (unit failed to power on or charge), I had issues with the laptop shutting down when running intensive games. I opened her up yesterday and found that both cpu and gpu had gaps of no liquid metal applied. It had a grey/black tint in that area. I reapplied LM on both the chip and the heat sink.... been running smooth with no shut downs or notable throttling.

Thanks for this amazing guide. Used this on my G16 and my laptop would lag HORRIBLY and make games unplayable. I went from 95C to 80C. Unreal, thanks!

Same thing with my scar 17. Bought a laptop and it was constantly overheating except when I used turbo mode. Had to repaste it. Now it works just as it should

Thank you so much for sharing this! I had no clue where my performance had gone to and my CPU would instantly spike to 95 degrees.. Throttlestop would help occassionally but i really just wanted to fix it. Upon opening there was literally no liquid metal left in the middle of the CPU.. I retook your steps and bought myself some Thermal Grizzly Conductonaut and now we're back to idling below 40 degrees on normal tasks. Thanks again for showing how it's done.

i call Asus official in my country they say this is not void warranty but liquid-metal must not spill to any part on the board and every screw must not be over tighten. what a great news

Thanks a ton man for great tutorial! Mine was hitting 97-100C on one or two of the CPU cores all the times. Same thing - really bad paste job from Asus. On mine even GPU was bad - the contact part was black even :D. I repasted carefully and now CPU sitting 75-77C hitting 85 tops on 1 of the cores. 100% worth it!

Damn that's nice! I sold my scar 17 SE because of the Temps, I've been repasting laptops but not really comfortable enough to repaste liquid metal. That's a nice work man! I hate how rog ships this high performance machine with shitty paste job :(

My cinebench r23 score before repaste: 26.6K After repaste: 31.8k Manufacturers need to get their game up.

I did the same to my asus scar 17 ryzen9 7945HX - rtx 4090, I'm surprised how the difference is now I'm getting more than 20 degree low temps !!! I can't believe it my temps was like 97 while gaming now almost 80 and my fans went more quiet than it was my cpu also getting more wattage , thanks for sharing this video I was afraid to do it , now I wish I just made it since I bought it.

Hi thank you for the helpful vid. I have the same model and have been seeing temps as high as 106c in hwinfo so I figured it needs a repast. I reached out to support and apparently your allowed to repast the device yourself without voiding warranty as long as there’s no damage caused.

I did this recently on my new scar g16 2023 634jz thanks to your video was very easy. mine was pasted good except needed more on gpu i put a bunch also arctic silver mx6 on all other components and i improved the performance a bit and its cooler alllaround thanks

Thanks for the video, had a very similar view to yours when I opened it up, repaste improved things greatly

Top for people who did this and didn't spill and didn't get their laptop to turn on, it just sitting there with the keyboard glowing... I thought i messed it up! But no.. hold your power button with the power cord unplugged.. it will do a cold boot and will then properly boot. It likely is a result from unplugging the battery.

Great ! Its always better to repaste even if it has Liquid Metal. Well done. I would say that it’s crazy to see this laptop has so much wasted space inside . I mean you can stuff a lot of things inside such as coins , pens, condoms inside. Look at the space around battery and that dongle which connects usb or card reader. Hilarious … in comparison MSI GT77 utilise all the available space. The new MSI HX 18 took the Scar root and has wasted space as well. Crazy

Same thing for me. I opened it, it didn't look too good, CPU was going 95+ and GPU slightly throttleing. After liquid metal ( I have on CPU only ) + thermal paste on GPU, in cinebench CPU would go only to 85C and in timespy 81-83C. For GPU scores were insane, in timespy max 70C ( absolutely madness ). However, now after 6-7 months, I'm back to throttleing and bad temps...why? no clue. ambient temperature is the same, it seems that in time it just went to shit. The only thing I'm not sure about is the VRMs + capacitors + whatever other electrical components the heatsink cools. I replaced the old "thermal goo" ( it's actually called thermal putty ) with thermal paste. In theory it should be way better, and it was, as I said, INSANE TEMPS, but now not so much. I ordered thermal putty (upsiren ux ultra or smth ) and a new thermal paste ( from upsiren also, apparently 14.8 W/mK ( vs 12.5 W/mK that thermal grizzly has ), but it'll take a while to arrive as I didn't find any locally. Once they get here, I'll clean up everything and reapply liquid metal on CPU (thermal grizzly one), upsiren paste for GPU and upsiren thermal putty for all the VRMs and stuff. Hope that will be as good as things were initially for me ( or a little bit worse, I don't mind as long as GPU is under 80 and CPU under 85-90) and last for longer than few months. Any chance to get a reply on your laptop, how are things now after 4 months or so? Thx

I have a scar 16 and temps are horrible on only 2 of my pcore it spikes to 96-98 suddenly and its causing my system to thermal throttle bc of those 2… i bet its a bad application as well will definitely check it out when i have the time

Legend! My laptop had a massive hotspot reaching 110 celcius.. on heavy tasks especially on stock GPU settings it could randomly go into an emergency shutoff and.. only fix was a heavy heavy down clock and hope. Did this (my first time doing liquid metal) and carefully and its amazing.. hotspot temperature is now only 4 degrees celcius above the also much lower gpu temps.. i max out at 80 celcius with no undervolt and an overclock applied even.. fans are much more silent and the shutdowns are gone! Asus does not know how to apply liquid metal.. thats for sure.

Hope i didnt damage anything on my zephyrus g14. Comp never shut down but I recently noticed my cpu temps about 92c while playing TFD. Been gaming on it for about a month now. Its never had any performance ISSUES persey, but i started paying attention to how fuckin loud it was, thats when i caught the temps. The gpu is fine, but the cpu is BAD. Ordered some liquid metal, a gt600 pad, and some gelid thermal pads and im redoing the ENTIRE laptop tomorrow. How would I know if i did "perminent" damage to it?

thanks man, on my g18 went from 17k cinebench multicore to 31k

Also, when you do this, you may have to replace the thermal plaid around your GPU for this. I recommend Fuji ploy, extreme or ultra.

brilliant video my friend, so interesting for me, i've always been curious about delidding etc and this video has given me more of an idea what i must do if i ever dare to delid in future. Subscribed 👍

Today i changed liquid metal on my strix scar 18, on cpu side like in your chip, there was a little piece of paste missing at center, but i got paste on both dissipators chipset, the bad one applyed was on gpu side at the bottom, it was a little black like was burning, i swipe off all of it and applyed for my first time liquid metal, i got silver king paste cause from where i am it costs less and have 79W/MK ''they say that lol'' so i go for it, not was so difficult if you manage to change it in dekstops, i got 32.8 on cinebench not 34-35 unfortunately but on 10 min i got a boost up to 30.7 from lower 29s, also less temperature on GPU while gaming and a bit frames too, follow this video and ceck/change it because this is the mayor cause when a laptop stop work, i lost an asus years ago with 980m cause bad paste work, i was always hitting 100C at the time haha but i'm not was so practical at the time for change it, thanks for the video, it was really helpful Ps, i broke the sticker but i don't give a fuck, if I hadn't opened it and change paste the 4090 would have caught fire lol

After 3 years with my Asus Scar G17 from 2021, 3080 w/ Ryzen 5900hx, i finally opened it and saw it was also missing liquid metal in the middle and poorly repasted. I have been wondering why my CPU temps have been going to 97C when I first bought the laptop. I repasted it and also noticed that the paste covering the CPU part that could short circuit from liquid metal was not covered properly. I literally took pictures and have proof of it. There has been many issues with ASUS and their RMA process so I think they are doing it on purpose.

Ar what temps should i start to get worried. I average around 95⁰ under stress on cpu GPU is usually pretty low though

Thanks for the video!

If I got this laptop or even ryzen 9 7945HX.. I'll also open it and readjust the liquid metal.. the issue is same with me when I'm using Ryzen 5000 + RTX3070 model 2021.. Great Job BRO.. maybe Asus should take us work under them XD

This really works well thank you!

what's your idle temperature and on operating temperature? mine idle at 60'C or 140'F. when doing web browsing and playing video at the background at max 80'C or 176'F. Just to let you know, my ROG Strix G15(2022) did some RMA last year to change the motherboard (expect the technician did the repaste). When gaming, mine go up to 95'C or 203'F

Had same stuff exactly looked like Yours unfortunately losed warranty at sticker point but seems that was pasted to run to fail anyway

Hi, why didn't you remove all the LM and reapply the new one? Is it just to avoid using too much new Lm?

Great job!

should i just wait until my warranty expires? I have the Asus ROG Strix G18 with a 4080. My score is 25,500 without undervolting. I don't know if removing the sticker is gonna void my warranty which ends this october, or risk possibly destroying my pc while trying to reapply paste lol. I've had it for 7 months anyways. Also, you see the white paste around the cpu and gpu when you lift the fans & heatsink? What is that? And does that have to be replaced too?

The machine that applies this LM should be decommissioned and the person in charge of it fired. This is completely unacceptable for such an expensive machine. I believe each LM application should be applied by hand to pretty much guarantee it was done correctly. Nice video tho! Thanks for the information. I’m gonna try this on mines.

Very helpful guide for noobs! Just redid the paste first time ever!

What are your idle cpu and gpu temperatures after the repaste compared to before repaste?

its the tape that caused it to spill as it is a very slipery surface .

I'm having this issue with my Asus Scar 17 SE but i have no skills in removing the Vaper chamber to get to the CPU and GPU let alone repasting the liquid metal

I tried PTM7950 instead of liquid metal and it works better on high temps (like couple degrees lower) but on low temps its now so efficient

Run the same CBr23 test for 10 minute loop and get back to us.

I'm in Brazil and I liked your video. I have an Asus G18 with the same CPU and in Cinebench R23 the score does not exceed 26k. I will do what you did to see the final result, but I was thinking about adding thermal paste due to the risk of running liquid metal into the motherboard component. If the swab had a magnet tip it would be easier to remove, right? Thanks!👍👍👍

Have you ever found CPU issue stuck at 0.39 HZ when turn laptop on and then plug in adaptor immediately?

Do you have to remove the whole heatsink to clean coolers from dust or they can be removed separately?

I am on Rog Strix Scar G733CX with i9-12950HX. Pretty sure i have same problem, just ordered liquid metal, and will do the same.

That is a really bad job from ASUS. I don´t know how other manufacturers do it. Done this my self on my older Legion 5 a year or two back. But the instructions were clear. Spread a thin layer on the die and a thin layer on the heatsink. Works great till this day. On my G16 (13980HX RTX 4080) it works well. In performance mode it stabilizes at 80/80°C at 21.5°C ambient temperature.

I'm wondering what thermal paste was used on the voltage converters and Vrams. There is Tputty that can be used to fill larger gaps than with normal thermal paste. The disadvantage is that the thermal conductivity is poorer.

What are cpu and gpu temperature before and after repasting

My problem right now with my g18 4080/13980hx is that it scores really high(34500ish), but 4-5 cores are always throttling along with power limit and current limit throttling. I can apply pretty aggressive undervolts in xtu, -.150core, -.100 pcache, -.150ecore, -.040igpu, -.040 system agent, and the system seems stable scoring around 38000 CBr23. Yet it always thermal throttles. I’ve even dropped core ICC to intel’s recommended 215a vs stock 240a, and it still throttles. Idk what to do, I started looking into it due to a constant stutter in games. Should I repaste?

Asus need to be ashamed. How come PS5 has better liquid metal reservoir/bowl vs what ASUS have. It will be freaking hard to splash LM on PS5 due to this reservoir/bowl which equal it will stay there even if you open the heatsink/vapor chamber.

can i repaste my g18 non-scar by following ur steps shown in the video?

Hello i have the same laptop strix 18 with 4090 but i have 0 experience in doing this. My laptop cpu fluctuates 80° to 95° while watching videos and doing stuff and it remains to 80° or 85° while gaming (sometimes less) and it's 55°/60° while idle. Do you think it's better to do something? Or undervolt maybe? Please let me know, everything is smooth but i feel like temps are high on CPU (gpu looks fine)

Hi, did you use normal Conductonaut or the "Extreme" ? Because I have a G14 2023 and also experiencing bad temps. Like even with CPU limit on 20W, It gets to 83C even tho I limit the temp to 83C. But my Cinebench scores are normal, Ryzen 7 7335HS scores around 13-14k. Still have warranty from Asus, should I replace it my own or from them ? I'm afraid they'll just do the same like factory settings and said its done. But last 5 months the temps were good in the low to mids 70C.

Do you know what the protective seal against liquid metal spillage around the CPU and GPU is called? I removed it because it fell off when I lightly touched it. It’s very soft and spongy. Without it or a replacement, I’m afraid the liquid metal will spill out and destroy my computer.

Is the part contacting the processor nickel plated?

Does the 2023 Strix Scar 18 have the same fans as the 2024 model if i wanted to replace them?

yea I pulled mine recently and there was no liquid metal in the middle of the die.

Hey just bought the exact same laptop. Does your trackpad sound a bit springy when you press it? (Maybe this is normal for asus laptop trackpads, idk) I hit 31369 on cinebench stock. I feel like these laptops are hit or miss with some of the QA.

I get 90C cpu tems with strix18 while doing nothing or just browsing ffs ASUS

It's good you unplugged the battery. Their application is shite. Have you considered thermal pad? I'd be curious to see a comparison. Also saw a video where someone used both new past on top of a thermal pad and got even better results than either individually.

What is that around heat sink 33:06 to protect spill of liquid metal

I guess my laptop dies. I was very careful for LM. Adter i did repasting laptop resets and not get logo. I wait like 5 mins and laptop resets in every 30secs. I guess need to send to rma

My Scar 16 (mini-LED) 4080 is shutting down in certain demanding games. CPU hitting 100C and GPU 90C... the funny thing is this was RMA'd once already for not powering up at all and got a new motherboard. Terrible QA QC.

hi mate , i have the smaller version , the scar 16 2023 (G634) , do you reckon i can follow your guide for mine as well ?

I have an Asus Rog Strix G16, do you think the same thing happens? I don't have high temperatures, or so I think In demanding games like Dead Space Remake the GPU reaches a maximum of 80° but the CPU sometimes reaches more than 90°, although it is normally between 80-85° Btw rtx 4060 and i7-13650hx

I have the Asus ROG Strix Scar 16 with the same problem. Things looked even worse for me...seems to be a big problem. This shouldn't happen with a €3400 laptop. I drive 40 km to work with my laptop every day, which is why I suspect that's why the fluid leaked.

I did this and put everything together but now I don’t get any video. I double check and I did not spill and Liquid Metal anywhere

Can you a guide via bios to do a permanent underclock

Is there a huge difference between conductonaut and conductonaut extreme? 😁😁 Its just a little cheaper lol Im gonna be doing this! Wish me luck! And thank you for showing us how to do it

Is the heatsink the same model as the 2024 Strix Scar 16 version? I have placed my order and its arriving soon and I plan on respreading the LM as shown in the video. Also is it fine to attempt this without having extra LM paste?? Im hesitating whether or not I should risk opening up the laptop and realizing that I didnt have enough paste to begin with.

mine is 6 month old cine bench r23 stock 27700 undervolt 33500 when run cinebench r23 temp of p core 1 3 5 7 temp is much higher than 0 2 4 6 specially core 1 and 7 it is 95c and throttle while other like core 0 and 2 is just at 70c 25 degrees dif omg But i worry about warranty

When i play games, my usb randomly disconnects. idk if its software issue or heat reated issue. Upon researching. it seems like when laptop gets too hot it will disconnect auxiliry power. Which make senes ot me because it only happens when im gaming. So i maybe getting thermal throttled. I will try this solution.

​@XyonusTV Do we need these black folies over ram and ssd? Today i put new ram and ssds with copper heatsinks and good thermal pads plus also wifi 7 chip, it fit all perfectly but I am wondering if i should remove all the black folies for better airflow or to keep them and make sure they stick good. Do you know?

After repaste. From 94c to 86c

tips on removing battery ? I am always afraid to do so.. cause I once sparked my 2021 G14, and now gonna repaste my 2023 G14.

i need help man, i have a scar 16 but the left fan when on high speed is making a vibration sound, did i assemble it wrong? Update: I'm dumb the plastic folio behind the fans were bent that's why it made a sound fixed it. In the end i didn't add extra lm but spread it and gained 5-6 degrees on the gpu for performance mode. Not bad

anyone think that is too much liquid metal?

hi, i have the 4090 scar 16 version from 2023. i already get just over 34k with an undervolt, do you think i should repaste anyway? i use my laptop for the past 3 month on a laptop stand which angles the laptop downwards. do you think the liquid metal has probably moved and pooled at the bottom of the two dies? thanks

what did you use on the vrams? looks like thermal paste and not thermal putty on the vrams?

What about the capacitors (or vrms), do not they need to be repasted?

How about the VRM's ? I have the 2021 version of this laptop and i am thinking of repasting it, and i was wondering about the VRM's, did some reasearch and people reccomend using thermal grease which is thicker. Or should i just leave the one it comes with ?

I have ROG Strix G15 running at full load with overclock at over 90C. I'm planning to repaste the liquid metal with "Thermal Grizzly Conductonaut". Will it suffice?

Asus used the exact same logic you did to justify adding more 😂. The next time it's opened, prepare to kick yourself 😂

now i know why my ryzen 7 is reaching 96 degrees celsius

i have the strix g614jv which is very similar to this model you got here. so, for a laptop like this, what is a bad temperature? i mean it gets hot while gaming but i haven't measured the temps in games; normally sitting on the desk with some light web browsing, cpu is about 46 or so; and gpu is about 36. is this high or not?? i'm really worried about my tepms and the paste :((

I got my cpu and gpu repasted today and the liquid metal was spilled to the side and the cpu has a burned mark. I switched it to a gold grease thermal paste, is it ok?

Hey I have the scar 16 and i would like to change past cause I got high temps and some freez can you tell me if I use this past is good or not Thermal Grizzly - Kryonaut Thanks

hello, the transistors or transformers around the gpu and cpu are already protected from the factory? Because I see that some of the factory metal has spread out of the chips.

Sir how much temp difference did you get and did warranty get void ?

I worked at a computer laptop repair store and i know this stuff but i never did a re apply on liquid metal . I have an asus ryzen 7 6800H g513rm still in warranty but i think the temperatures are really bad on stock liquid metal. I was wondering Is it worth it to void warranty to re apply liquid metal on it?

Can you provide Amazon link for this paste

Do you also have to reapply thermal paste on the v rams?

What would constitue bad temps - I recently purchased a ROG Strix G15 Advantage Edition with a Ryzen 9 and 6800m, when gaming the keyboard was getting warm the temps were between 80oc and 91oc while gaming. This device is under Warranty (any advice) thanks for the video provided a deep insight"

Hello! I have scar 17 (2022) i9 12gen 3080ti. Do you know what termal paste to apply on vram memory (light blue paste) .I ask that because in 2 years I cleaned my laptop 3 times, but only fans without remove heatsink and I found blue thermal paste (dry) in my fans and around fans and I want to replace that paste too. And now my laptop are not really good beacuse only in turbo mode i can play games because thermal throttling... :(

I tried repasting my lm and it broke, why? I didn’t spill a drop of lm anywhere

What about all the paste on the little things around the cpu and gpu? no need to redo that stuff?
