How to Flush your Watercooling Loop 

last time I did this my mom thought I was cooking meth

Thanks Jay for making content that's still relevant today. I've been watching your vids for a few years now, and finally have built my own custom loop with GPU block and CPU/vrm monoblock and 2 rads. I would've been kinda lost without being able to refer to your older videos

I just gotta say that I've always loved your content and have never had an issue with it, but ever since you redid the office to be more build friendly, your videos feel completely re-energized. Keep up the great content, man!

I swear, one day, when I am able to simply afford a water cooling, I'll be quite an expert in theory becaus of such videos which I've been watching on a regular basis for like the last 3-4 years!

My mom thought I was putting Gatorade in my PC lol

I love the maintenance part of this hobby. I clean my loop out like 4 times a year. Its not necessary at all but I just love it 😛

I'm lovin' these two man made videos. Having handheld footage while you do stuff is super great. Keep up the awesome vids guys.

In my old rig, I never changed the water. I used distilled water and a silver coil and just refilled the reservoir once in a while. I had it running for like 5 years, no issues.

Good video! Built my watercooling loop almost exactly 1 year ago and been thinking it's about time to swap the fluid. This was exactly the method I was thinking basically and should just be really smooth and should be fixed within 1½h max.

ive never taken apart a block before, had no idea those fins were actual fins (ive only ever seen solid blocks, not the clear ones so when i heard people refer to the waterblock fins, i imagined somewhat chunky slot like channels for the water) very cool

I love your videos Jayz. They cheer me up so much from my depression. So a HUGE thank you !

Really liking the workshop feel of these videos again. Nice to see you went back to your roots

Changing my fluid out for the first time and remembered you did this video. Watching this first and then going for it. Thanks Jay!

Thanks jay I really appreciate the knowledge you put out there. Did a deep clean and found black gunk in the block gasket i saw your video and never knew you can buy replacement base. Thanks again

jays videos are always solid in terms of informative/educational content. no BS just good stuff know

Perfect timing Jay! I just purchased a used 290x with a full coverage XPSC block, a 360 rad, and a raystorm block for my R5-1400! Of course I also got fittings (also XPCS) tubing (primochill flex (also comes with biocide)) and a res/pump combo.

Thanks for the quality content, single handily you have talked me into making my own custom loop

Thanks for the excellent video Jay, I watched your video last year on tube bending for my first hard tube watercooling loop, it was a great help. I have a dual bay res on my current build however i incorporated a drain port in the case so you've given me some awesome tips when i need to flush this loop :) I really need to convert to a tube reservoir though.

You make it look so easy, I really need to try out a water cooled build, I've still never done one which is probably why I'm a little nervous about it lol

This is very useful and easy to follow! This is why Jay is the man when it comes to watercooling!

The god of water cooling, providing more watercooling tutorial content and showing us just how he earned the title!

Thanks for the video Jay, I was interested in water cooling my next build and I really didn't understand how maintenance would work on it.

Informative video that shows basically everything to my questions. Thanks Jay!

Actually had a few of my friends ask me where to recycle used cooling liquid. If you have a town recycle center, they can usually accept it. The best thing to do is look up the composition and write it on a piece of paper with the bottle and then tape it there. Some parts stores may also accept it. If worse comes to worse, contact your city and ask where you can recycle it. That's all I can think of. Great video though Jay, really does help even though I just use an AIO.

Found out the hard way that my custom build didn't come with a drain port.. these video's are superb, cheers Jay.

Thanks Jay was looking for the secret power loop to make an external ps work. Concise as usual!

Straight forward and easy. Thanks for the video Jay.

Loving the content, keep it up man!

Just watched your watercooling myths video an hour or so ago, what great timing for this one to come out

okay 5 seconds into the video and i gotta say jay the PC shop background was the best option the channel feels great.

@jayztwocents I'd love to see you fully build a water loop, but show us in detail every step you take. How you turn the knobs in, close-ups on the o rings while you close them, and things we should focus on while you work.

Jay, love your videos man, stumbled across your channel randomly one day watched a few videos, subbed and have never looked back - always look forward to your videos! Can't wait to see you in Scrapyard Wars (my 2 favourite RU-vid channels). Keep doing what you're doing man

I feel like its been a while since I've seen a watercooling video here, I appreciate this. Can we get some more soon?

Have pretty much everything for a custom loop, exept tubing and a pump. Unsure how much cleaning the components need, and how to do it. A video of propper clensing would be cool aswell :D Keep up the good work

Great video thank you Jay Also a 15-20USD digital power supply tester also works as a jumper to turn on your PSU and you get to check your PSU volts at the same time, no jumpers no clips pretty much idiot proof, plug it in and the one I have has a 30 minute duty cycle In its simplest meaning you can run it 30 minutes then you need to let it cool down 30 minutes

I'm freaking out over here. Flushing out my system. Following your steps to the t and the sirens have yet to start! What do I do?! Please help! Lol. I have only recently discovered your awesome channel, but I really enjoy how you don't let background sounds interfere too much with your content. Like a comedian giving a heckler a bad time.

This was very helpful. Thank you Jay!

Jay! I like these type of vids man!! although I already know how to do this stuff, It is helpful to others!

Nice video with useful tips. Thanks! How do you clean a reservoir that is a little bit cloudy?

I like jay-z's Chanelle he's just cool down to earth and I could watch his videos all day man

@JayzTwoCents Thank you for this very informative video! Last christmas I built my first custom loop inspired by your videos and teachings. I'm using distilled water mixed with 1/10 EK Clear Concentrate. How often do you think I should change the fluid? 1-2 years?

you make it look so easy Jay. I am wondering for a first time setting up a loop, would you suggest to do it on an old system or on a brand new system?

Jay, you should have totally done a slow mo troll shot of pouring the straight water into the jug when measuring out the fluids. Would have been perfect!

keep up the good work man! love the channel. you are my favorite on youtube! dont be mad but you kinda reminds me of linus before he became so corporate

Awesome job on the video again Jay.

I use distilled water and glycol as cooling fluid. I have flushed the system 3-4 times in the past 8 years (at same time any hardware changes have been made). Only when needed. The buildup and gunk has always been very minimal. Use case varies from heavy duty cryptomining with 3 AMD GPUs 24/7 a few years ago to light gaming with a single nvidia GPU. All copper loop everywhere, no mixed metals.

I actually learned something from this. Thanks JayzTwoCents.

I just love you man, you really make me laugh in every video.

loving the maintenance videos jay, any chance of one for cleaning radiators with quite a heavy build up of dust. I had literally a dust rug suffocating a rad peeled off got the compressor out blasted most of off and then used a small soft brush and some isopropanol (sorry bad spelling) but there are some stubborn bits still clinging to the fins that refuse to budge. Its a AIO so i dont feel quite comfortable taking it out and running it under hot water in case any water works its way into the pcb of the block and possible water stains on the black sleeving as i live in a hard water area.

Hey, your watercooling videos are therapeutic. And you always try a different color. Thumbs Up!

Instead of huffing paint Jay huffs water loop coolant!

Nicely done Jay!

I'd like a compilation of street sounds from every clip you've made since moving to the new studio. Then, I could fall asleep at night. kthxjay!

Hey Jay. If you could demystify something for me, I would really like to see a video on coolants that are ok for soft tubing vs only for hard tubing, I ran into this issue with some of Mayhem's pastels reacting with soft tubing and turning brown. Also different types of soft tubing and hard tubing and your recommendations.

I'm an engineer and I build my waterloop and realized that if we use a total of 3 drain valves with an open port on the top of the reservoir per loop (in case you have dual loop) to create flush system and drain system (drain system is just a single drain at the lowest point of the loop. As described in the video. The 2 drain valves will be joined together with a T fitting One of the drain valve will go to the return of the reservoir (call it return valve), while the other will be closed and sealed (called it seal valve). When we plan to flush the system, make sure the pump is off. Then open the top of the reservoir, and connect it to a pool of distill water. Then remove the seal on the seal valve and connect it to a bucket or what ever you use for your waste liquid. Then turn off the return valve, and open the seal valve. Finally turn on your pump. Depending on the size of your distill water pool and what you use for you waste water, you can technically have it going for a while. Once, the water is clear you can even connect the seal valve to the distill water pool to keep it cycling.

Perfect timing, I need to do maintenance on my loop this weekend.

Would love to see a video about Ram cooling. Stock vs. Fans (Like the Corsair Dominator Airflow Platinum or Vengeance Airflow) vs. Liquid.

I like the ａｅｓｔｈｅｔｉｃ color scheme you went with the system.

Seeing that blue coolant makes me want to see you do a Tron themed build!

Hey Jay, could you make a video on how to minimize maintenance? I really want a Custom loop but dont really care for fancy colored water of even see trough components. Would non see trough parts with thick rubber tubes last longer? I'm not into flushing my loops that why I never went past a AIO.

PT Nuke + Silver Coil + Distilled Water. I don't put any dyes, just run colored tubing with RGB blocks and res. Lasts forever, less chance of gunking up, still looks good.

Thanx Jay. It's been over a year so about time. Sometime this W/E.

Good video! Thanks Jay.

Somewhat off topic, but I started my custom loop after watching your vids. want to replace my XSPC Photon with an EK pump/res...what pump is on this build??? Thx

Jay what actually causes the coolant to change? Is it just over time, or is it over time while its flowing around the loop over parts / constantly changing temperature (eg: it cools when the system goes off). Might be interesting to put a sample of coolant in a plastic bottle when you do your builds, and when you come to change the fluid, you can compare the fluid you drain out of the loop with the original sample and see just how much it has changed, obviously if the fluid changes over time regardless then this won't work but I was curious

Hey jay do you think ek will ever have an aluminum line of fittings and such? I like the idea of it but as of now since it’s just the kits you don’t really have the expand ability factor like you would with a copper/nickel line and That’s one of the best things about water cooling imo

+Add to: Favorites Thank you Jay.

Had to again comment seriously Jay this was super helpful.

Would you recommend to dye the cooling fluid for maintenance reasons? I mean, you can see there the fluid went, where you definitely have to clean up. Wouldnt be so easy with clear fluid

Epyc, nuff said ;) you're a legend Jay!!!!

"So take your hose, put it in the hole" - some very useful and clear instructions from Jay xDD So i did as he said, wasn't disappointed ^^

+JayzTwoCents could we see a video of a custom Waterloop with a Peltier cooler to see temps below ambient as well as functionality/practicality. love seeing stuff that works great work even better. especially when it doesn't effect looks! Just food for thought.

Yo jay , you r my fav tech reviewer

I have always wondered how long an AIO will last in comparison to a custom loop.... Be an interesting video/research topic

Hi Jay, good job on maintenance

Jay could you do a small factor build in a Phanteks Shift (x) to see what radiators can fit in there?

I've never actually hadd the money or desire to build a water cooling loop, but I did research it quite heavily in my teenage years. Pretty much what I determined was never use any special coolant or dies, it will only gunk up the extremely fine micro channels in modern blocks. don't put aluminum parts in your loop, only use parts made of copper, brass or other galvanically similar metal, use a silver kill coil as it will release silver ion into the water which works as a rather effective biocide, don't add anti corrosive additives they are not necessary if you use galvanically similar metals also because they tend to act a sacrificial anode and overtime as the anti corrosive additive will react with metals in the system and it will suspend out of solution and can gunk up micro channels. Use only distilled water as a coolant because other coolants typically have lower specific heat capacities than pure water and the lower freezing point or higher boiling point other coolants provide over water is essentially moot because water cooling loops for computers are always going to be above freezing and below the boiling point of water. The only additive that may be useful in a water cooling system is a small drop of dish soap or some other surfactant to reduce the surface tension of the water to help prime air bubbles out of the loop. Also I think I had determined that it would be optimal to have the reservoir at the top of the loop or to have a reservoir that was as tall as the loop and keep the pump at the very bottom of the loop that way the pump always has water and having the reservoir at the top of the loop or having a reservoir that is taller than the loop should help keep air bubbles out of the system.

Jay should do a video on a budget loop, not a prebuilt loop or anything just budget components.

Hey Jayy, what are you thoughts, should we put Thermal compound on the CPU block, or should we not? Is direct contact better or worse then CPU -> Thermal -> Block?

A quick question, if I could sir. Any chance of getting a full tear down /flushing like you mentioned earlier in the video. I don't watercool, but I am not one to turn information away. Thanks for all the wonderful videos.

great video Jay :)

Got junk in my loop... knew Jay would have a good video on fixing that ;)

Jay is lookin swole bro nice gains

I have literally watch almost every single video even the ones back 2 years ago

why are people disliking this lol? it was great to watch and i jay is funny. great vid man

what is his pump res combo he usesd here i canot found one with extra hole to flash out

hey Jay, I got a question. We 've seen that aluminum air coolers don't perform as well as copper based ones. However in the case of watercooling like the Fluid Gaming from EK we saw that it performed very well. Why is that?

Simple and excellent video Jay, cheers. Liked the Pink Panther cut. So many comments to the tune of 'omagherd there's so much maintenance!'... get off social networks for an hour every 6 months (worst case) and everything's sorted. For true hardware nutters, the prime watercooling market, the absolutely miniscule time investment on maintenance isn't even worth a mention. I disown and distance myself from this 'entitled' generation!

I like these tutorial videos. More please

I see you updated the title... Good job!

im looking forward to see complete brake down video like how to clean the block, radiator and the clear plastic

Title was changed 3 times, and thumbnail twice. Still gets to the point though. Thanks for the info Jay

When should you change your thermal paste on CPU?

Depending on what the coolant is made of, it may be a mistake to assume that it will leave .75L. For instance one cup of isopropyl alcohol with one cup of water will not equal the same volume of two cups of water.

Is it safe to use something like white nylon tape or weak threadlock when screwing the res onto the pump? Mostly to prevent any liquid from seeping into the threads over time.

I would want you to make a video to compare a singel loop vs separate loop for gpu and CPU. My CPU feels abit more hot with gpu even with a added 360 rad at the same time. Im thinking about to make 2 loops instead, But would it be better?

Hey Jay, would it be possible for you to do a video on the best Ryzen CPU for gaming?

lets go jay :D love your vids :D

Wow You’re just so easy to work on because it’s outside the case I’m sure a lot of us is inside the case.. What if we just use distilled water? Instead of the C1000?

i do my loop every 6 months, but ive never used a pump res with a drain port, always done it the hard way damn it, which pump is this?
