Radiator Fan Configuration: Does It Matter? - The Workshop 

People say this series is pointless, but it's busting the myths that people have been shoving down beginners' throats for years.

5:31 you got your answer now go to sleep

Graphics card temps would have been a bonus, i would be trying to adjust the airflow to minimize temps inside the case.

I just want to thank you for doing all of these workshop episodes. You are putting all of the "Best Practices" of building PCs to the test, and actually giving us objective data.

what about the 2 up / down on the left pushing air flow down, and the 2 on the right 2 up and / down pushing airflow up, kinda like sucking it down and then pushing it up

the workshop is answering questions Linus answered 3+ years ago

for some reason I thought about my own fan configuration for like 2 minutes before I realized... My computer is air cooled... XD

The one irk I have with these tests is they do not seem to test (correct me if I am wrong) when the GPU is also at load heating up the air inside the case. As would that not potentially make it better to pull cooler air from outside the case? Would there be a way you could test that Luke?

Would have been interesting to have one side being in and one out, like front in and back out, so it would possible cause it to travel in a U-pattern through the radiator.

I like to place my fans on the bottom of the radiator for the looks, but as said in the video, it makes sense putting them on the top to make dust-cleaning easier.

please place the numbers on screen, it's hard to keep track of all of yhe.m

I really appreciate you guys doing these workshop videos. They answer a lot of common questions people would have when it comes to the added features of certain computer products. They also answer a lot of the more detail-oriented questions when it comes to certain computer configurations. Especially when we don't have the ability to test it for ourselves. Definitely keep these types of videos going when possible. The only thing I would consider is testing a few more scenarios in these videos if you can. I know you guys are busy, but for this video I would have very much liked to have seen what happens when the rad is front mounted. Also in the power supply video, if you could have kept things constant for the 80 plus ratings, for example all 80 plus gold psu's, then make a separate video based only on the 80 plus ratings then that would help people get a much better understanding of power supplies as a whole as well as give you guys more content to create. I know there are a lot of different ways to test these things, but if there were a few more controls as well as a couple of added scenarios that people may be considering then these videos would be just that much better in my opinion. That's not to say it didn't answer questions I had though. It still helped a ton and that's why I felt compelled to even say anything simply because of the potential this particular series of videos have.

What would happen if you have one side going in and the other out? Thinking this may maintain neutral pressure in the case.

You should do tests like this in a small case with bad airflow rather than in a huge case with almost infinite cooling options like the master case. Also it would have been interesting to see, which config is best for the overall temperature inside the case (GPU temp & mobo temp), assuming you'd only have the rad and one 120mm fan for ventilation (probably doesn't matter in the master case but with a small, poorly ventilated case it might make a difference)

4:14 @Luke how did you get your pants to push up through the rad???? I must try this configuration...

could a graphics card under load producing heat affect the config that exhaust air from inside the case?

What I keep learning from this Workshop videos is that nothing matters unless you do something really stupid like stuff your dirty laundry in your case.

let me think of a joke. people who make this joke is a joke including me

I have a h100i GTX with four fans but the Corsair Link fan cable allows me to monitor only two of the four fans with the software. Is there any way to monitor the four fans with the Corsair Link software ? I have made a lot of research on Google but i did not find a Corsair Link fan cable that allows me to plug four fans on it.

if i do a custom loop and set the radiators as you did do i need another exhaust fan in the case? or is it just fine leaving the radiators just pulling air in? Going to plan a full custom loop including cpu and 1 gpu

how about the age old "order of your water cooling loop" thats always fun. maybe you could try pump>GPU>CPU>rad>res / pump>GPU>rad>CPU>res / pump>GPU>small rad>CPU>small rad>res. mix it up a bit, go pump>rad>rad>CPU>rad>GPU>res. may need a beefy pump for that one

Damn, some people whine on here like it's their job or something.

luke did all fans pushing air into the rad, but what happens if you have 4 fans pulling air from the rad? I'm just curious

I'd like to see more tests involving different radiators. I think the quadfans would see a huge improvement over dual fans if you used a thicker, very high FPI rad.

Are we going to ignore that the Ghost Stories Dub was part of that sponsorship? That dub was hilarious

With the GPU not providing any thermal output into the case (GPU is idling and has a rear exhaust cooler), the difference might be negible. But what about a top-blower cooler installed on a hot GPU (R9 390X, Fury, Titan X, 980Ti) running at 100%. There should in theory be a noticeable difference in cooling performance between push and pull configurations of the radiator mounted fans.

I'm rebuilding my PC tomorrow with a bunch of new hardware, and one of those just so happens to be the Corsair H115i and this video helps me out a ton! Thanks Luke!

Possible questions: 1. could these different configurations have different noise levels ? 2. could these high end fans be too good to make a difference while other fans might not ? 3. Can you do a workshop videos aimed at noise minimizing scenarios in general ?

almost certain we did this along time ago.

And what about the case or GPU temps when you blow or suck the "hot" air from the rad into the case? This would have been interesting too btw.

Lol finally a follow up to Linus's video a few years ago. I run mine in pull like you guys do and it works just fine

Cool. I am building a truck and have the radiator mounted where the spare tire was. Tilted up around 10 degrees to get air out. But almost completely flat similar to your setup. I have my fans mounted above the rad pulling UP through the rad in a effort to have any derbies stuck to the underside simply fall, be blown away when moving, or lightly pressure washed away when the fans are off. I was unsure how well this may work as it seems everyone mounts there fans below. But after seeing this I am confident it will work as intended. Thank you

why not review multiple z170 boards? or give a lga 1151 build, new content has been pretty shit

Why didn't you monitor GPU temperatures when pulling air in to the case? I'd like to know if the reason we all exhaust our CPU's warm air out of the case has any truth behind it, since cable management didn't.

Linus I need some help. I recently replaced the cooling fan in my hp pavilion g7 laptop. now when I plug it in to charge it the laptop doesn't reconize that it is connected and supposed to be charging. what could cause this? any help is appriciated

can you tell me the type of those fan you use.. noctua what? i cant really hear the type of those? is that better fan compar linus use (silverstone ap121?)

4:14 Pants. Unmistakable pants.

You have already answered this linus.

Hi there! is the graphics card on this setup an open card or blower? would that influence the internal case temp more if it was an open card and having air push out of the case through the radiator increase temperatures in the CPU?

At 1:20 I love the hand gesture Luke uses for "up". Giggity.

Idea for new series on the workshop: how to mod [insert component here]!! It would be soo sweet!

wow the comments are filled with picky people complaining about this being a useless test, guys these videos are very informative for people learning about computers. Just because you know the results, it doesn't mean everyone else does too, some people are just learning about PCs and would like to know these things.

Just bought that cpu cooler and I installed it the way I thought would be most effective. Thanks LTT for saving me the trouble of having to take it out!

Could you test using high pressure fans on a rad vs standard fans. Curious to see just how much of a difference it will make.

YOU SHOULD change the name to "Proving Stuff That Doesn't Matter To Much"

0:42 Video starts 0:627 Video ends You missed out on 2 ads and several promotions. Sorry I couldn't save you from the Twitch Promo during the video.

Hey awsome video! Just one question: What if I put a couple of AF-14 on a very dense radiator (so that these poor air flow optimized fans would struggle to get enough pressure to move air through it) and then decide to add two more in a push-pull configuration? would they'll help each other so that they would not struggle anymore and maybe even get more effective than a set of 4 NF-14 (pressure optimized fan)? I think it will but it's at the edge of the distinction between air flow and pressure optimized fans... so... only a proper test could tell me!

Thanks for the info. Was worried I needed a new case for my new GPU, but just realized my PC has the radiator and two fans attached to the front fans. Now I can move the fans or the radiator w/fans to the top to make room without worry.

If LTT Keeps up this filler......even Naruto will be jealous.

from personal experience, the last time this actually made a difference for me was when I had no pressure optimized fans and I had them above the rad pushing air into it. I moved the fans to under the rad and it seemed to create more pressure as they became a lot louder and dropped my temps from 70c to about 40c

i have build my first pc and i just wantee to know n tell that one of the standoff near io panel was obstructing between io panel and motherboard so i removed that will it be okay? and iam using an old hdd which constists drivers of different motherboard and gpu?will it boot?

I'm still happy with just fans on top pushing out. Nothing below the radiator.

what about no fan at all with only radiator?

I was more interested in GPU temps with different radiator setups. Like, is GPU temp a lot higher when letting the fans blow into the case (aio as intake fan)?

What case did you use in this Video for the testing?

what about radiator placement? like if its roof mounted or mounted at the front of the case? could this make any difference to the temperature also?

Linus' videos are so good. Linus'.

2 last gen cards in SLI or Xfire or 1 new gen card for the same price.

how can I have fans setup as push into the radiator from front(outside the case showing RGB) and then pull from radiator(inside the case showing RGB inside)?. mostly RGB fans lighting is present at one side, and if I want to show RGB inside my case then I end up having setup as push/push.

what about the radiators position?Does it matter if I put it in the rad in the front top or back(even with tubes streching)?

you didnt do the front radiator setup...

Click fullscreen and type awesome

Does anyone know what case that is? I am looking for a new case and that one looks like it would have enough to fit all of my hardware in! Any assistance would be awesome!

So i have a Carbide 175R RGB case and i have a Corsair H100i Pro RGB Liquid Cooling 240MM, Dual ML120, PWM Fans, i7-9700K, ASUS ROG STRIX GeForce RTX 2060 Super. I noticed when i play Call of Duty Warzone on High Settings i get 144 fps and my GPU temp skyrockets to 82 degrees celsius. Is this too high? I noticed i dont have any fans besides the RGB fan behind the logo and the 2 Radiator Fans. Should i buy a 120MM exhaust fan to mount on the back to help pull air out of the case? Would that help with the temps? Any advice is appreciated. Also is it bad that the radiator is mounted on the top? I built this PC with a friend and i think we put the radiator on the top because my Graphics Card is so big it didnt have space on the back, but i dont remember. Is just the Corsair H100i enough to properly cool this build? other than the AIO i just have the RGB fan behind the logo and i dont even know how much it helps. Also i have no idea if my 2 Fans on my Radiator are pulling air into the case or pulling air out. Seeing as they are the only 2 fans in my case besides the weird RGB one behind the logo should i have the fans set up to 1 pulling in and 1 pulling out(exhaust)? How do i change this? I assume the best bet to help with cooling would be to add a 120MM exhaust fan to the back of my case to pull the hot air out of my case? as i have no fans besides the ones connected to my radiator and the RGB one behind the front logo which i dont know what it does? exhaust through front panel i assume. Sorry im a bit of a PC noob :(.

What case was that?

You only benchmarked the CPU, this doesn't account for the GPU heating the internal air. Using warm air from inside the case to cool the CPU will be worse than cool air from the room.

Thanks. Very needed information for me just bought CorsAir Cooling.

my question if you have a high airflow on top and a static pressure fan on bottom would that work? or would you want both of them static pressure?

LTT running out of content iideas

I would have liked to have seen the results for no fans at all.

Love these workshop videos. Suggestion: A video answering the question, does it make a perceivable difference? I don't want to see internal temps, benchmark scores or calculated frame rates in the corner of the screen. Take 6 machines of verifying build and cost. Game for 5-10 minutes. Cycle everyone around the room. Have them score/rank the machines. Can you/they tell the difference?

what do you think of Push-Pull Config with Corsair SP120 as Push and AF120 as Pull? or should i just use all SP fan on both side

So who is here because their vessel subscription ran out? Xd

do a vid comparing pressure optimized fans vs non pressure optimized/cheap fans also so fan size, 120mm vs 140mm

I wanna know that should you place the radiator on top or on the side (240mm) when cooling the CPU

Would there be a difference in temperature if you're working with a smaller case and a high GPU usage in terms of blowing air into the case through a radiator or out? Or would it be the same result here albeit maybe higher temps on the CPU?

That strawpoll was confusing

LinusRunningOutOfTips

Im a noob at watercooling, so these may be stupid questions: Push is where the front side of the fan is facing the radiator, and pull is where the backside is facing the radiator, and push/pull is where on one side the front faces the radiator and on the other side the back is facing it, right? Also, I'm looking to get an h80i v2 for my i7 6700k, and will it perform better than my current phanteks ph-tc14pe? Final question: I heard that its not worth it to do a push/pull config on a watercooler like the h80i v2 because it isnt dense/big enough to make a difference worth the money. Is that true? I also heard that h80i v2 comes with 2 fans already so even if its a small difference i can still push/pull.

It was good to see that there is that three degree difference though. This test has good control, but I'd imagine you can squeeze another few degrees with that extra three by improving the intake in other parts of the case. All that extra airflow on the radiator exhaust needs something pushing air in as well. At the least you'll be getting positive pressure and not sucking more dust into the case.

25% of this video is an ad

"It's not a graphics card - don't know why it has GTX in it." More like "nvidia cards aren't high-end, late 1960's performance cars. Don't know why they have GTX in them."

Would it matter if u mount radiator tubes done or up if u where front mounting radiator with a Corsair h100 I platinum or a kracken x52

+LinusTechTips what case do you recommend i get for the 7700k with a Asus Z270e And Corsair H100 i V2

use the stock corsair fans. they will blow away these f12. see what I did there :)

To be honest, I am not fond of these videos. Between something like Scarpyard Wars or 7 Gamer 1 CPU these Workshop videos have somthing like a filler characteristic to them. I know they take a bit of time to make but most of the questions asked were answered years ago, even by yourself. If you need "fillers" why don't go back to Unboxings or something like the "LED Lighting for Video", or "HOLY SH!t"? I like Luke as much as anyone here but the workshop videos don't do it for me. Just to be clear, it is not Lukes fault, it is just that the Workshop episodes have nothing for Viewers who are following you for years. Love you guys Greetings

This happens to be the exact cooler, and fans I am using on the radiator (yeah I know its not a huge coincidence, their both very popular). Informative video! Awesome as always.

I think a video around how much does the speed matter in RAM would be a good idea for a Workshop episode. Not sure if you guys have done this before...

could you actually do some reviews for a change? we havent had a proper review since move

Damn i miss luke and old ltt in general, things change but lot of good people left and the videos sort of lost their charm

I want to know if there is any difference in temperatures between a custom watered GPU and the corsair AIO GPU bracket

when puling air in the case was the ambient case temperature or videocard and etc.. affected?

vid came out 10 sec ago xD

No graphs. What? All verbal opinion, really LMG?

i had my raditor installed like this. "RAD FAN -> RAD -> Front Panel" pulling air blowing towards my cpu block. is that ok. or should my rad fan blowing through the radiator and air blown towards the cpu block? watching this in 2019.

>Opens video >Luke >Closes video

how would these configurations affect other components like a graphics card? if you pull air down through the rad, would that increase the ambient temp inside the case, increasing in turn the temp of other components? or would the hot air from the gpu going through the rad be less able to cool?

I have 6 fans 3 with a kraken x72 which is on the front of my nzxt 710 case pulling air in, and I have 3 nzxt fans on the top of the case blowing air out, also one rear ran blowing air out is that set up fine?

4:14 "and we have the PANTS pushing up through the rad..." Didn't know pants were that powerful, to create airflow! ;) haha

Can I just use the fan that comes with the Processor instead of buying a radiator and all of that? Please answer.
