Technical Deep-Dive: Closed-Loop Liquid Cooling

[@GamersNexus]

It's always fun to integrate more animations from GN's Andrew! Full article over here, including more info on all of this: www.gamersnexus.net/guides/2926-how-liquid-coolers-work-deep-dive

[@Syrupvip1]

Gamers Nexus should have added the Fractal Design Celsius series to that list 🤔

[@GamersNexus]

Syrup Viper That list is from our coverage that came out years before Fractal's coolers, but they are also Asetek.

[@Syrupvip1]

Gamers Nexus Alright thanks 😎

[@michaelsmith1675]

Now nzxt will send you more puck after this LOL

[@mr.tomatohead5648]

Gamers Nexus do you know which manufacturers target the -40° spec?

[@NZXTglobal]

Needs more Puck.

[@GamersNexus]

Are you pucking amused?

[@iLLixer]

Gamers Nexus did they really send over multiple pucks?

[@tmi1234567]

And more RGB? Are you guys going to make a Kraken x62 with clear tubes so that you can put RGB leds inside and light up the tube? that would be cool. I would buy 2 personally (dual xeon e5-2670's).

[@justin_hyde]

We need RGB Pucks! Get on that NZXT!

[@ichinichisan]

If we shadows have offended, Think but this, and all is mended, That you have but slumber'd here While these visions did appear. And this weak and idle theme, No more yielding but a dream, Gentles, do not reprehend: if you pardon, we will mend: And, as I am an honest Puck, If we have unearned luck Now to 'scape the serpent's tongue, We will make amends ere long; Else the Puck a liar call; So, good night unto you all. Give me your hands, if we be friends, And Robin shall restore amends.

[@Mr12Rishabh]

please make more videos of this type explaining various parts and their workings :) always love your content

[@paskowitz]

Rishabh Sharma I second this motion.

[@georgarak6105]

Motion is actually kinda correct (used in the UN, and most Model UN Conferences)

[@Lakshyakapila]

Sahi baat....🙂✌️

[@BillyMizrahi]

After having a CLC on my CPU and GPU for 4 years I finally understand how they work. Thanks! These deep dives are the best. Keep em coming.

[@alganthe]

And that's how NZXT managed to bribe steve with pucks.

[@revx1000]

Thanks for the vid. I was wondering exactly how my Kraken X62 worked! Now I know! This channel is the best for this sort of tech breakdown for PC's and accessories. Glad to see GN constantly growing in popularity.

[@GamersNexus]

revx1000 Thanks for the kind words!

[@RepsUp100]

I'm a simple man I see new upload from Gamers Nexus, I click watch. Thanks for the CLC suppliers list, I hope you release one for laptops, PSUs, etc. it's interesting to know which OEM supplies to manufacturers. Safe travels to Taipei!

[@SicSemperBeats]

yea I always find it interesting

[@Return_To_Sender]

Wow, so original.

[@erics9801]

Gamers Nexus and NZXT's relationship is priceless

[@brumby92]

Steve. You run the most in depth and comprehensive and informative website/channel there is. Always enjoy your content. Love your Work. Fucking keep it up mate.

[@mtucker6784]

Watching this in late 2023. You guys have come so far, thanks for the awesome content you guys always produce!

[@keybraker]

Thank you so very much for this video ! I really wanted to know the part about the fans, I always though how it worked, and although I was really close to the answer you made it clear to understand, very imformative ! Bravo !

[@Brandon-mk7oc]

Loved this video! I'd like to see something similar to this about custom loops. Obviously it would be more complex and have a lot more variation but even just the most commonly used stuff would be interesting.

[@drakegostream]

No wonder when I searched "how aio coolers work", GN Video popped up! You guys got us covered! Thanks for an amazing job again!

[@rodrigotvgad]

"Don´t use a drill to take it apart" That goes for you LINUS!

[@nahuelcutrera]

those 3d animation are awesome, this channel is upping the mark once again! great work!

[@fourtysix4646]

Great video, was more thorough than I would expect from a tech tuber. Surprised you even went into the coolant mixtures and tubing types. I would expect it to be around 20-40% glycol in these aios but if I had to guess it would be closer to 20%. Also that cracking he described in the inner teflon lining of the tubing brings up a important question for anyone with plastic piping in their house. What happens when the inner lining of the pex pipe cracks and either bacteria grows inside the crack or the chemical components of the plastic leech into your potable water system? Pex piping which is what is installed in new homes these days hasn't been around long enough for us to know it's safety long term.

[@mrpetebojangles21]

Awesome video and animation. I thought the bit about the BIOS misreading the pump’s RPM very interesting.

[@MarceloTezza]

That one was VERY GOOD video, with awesome presentation, very educative, with good in depth detail. Congratulations for all the involved, im going to put on favorites! For more videos with that quality, thank you very much.

[@GamersNexus]

Marcelo Tezza Glad you liked It!

[@junnnaid]

Beautiful graphics! Excellent presentation! Thank you! Keep up the good work!

[@vinyl7232]

This is exactly what I need. Thanks dude, great video!

[@DillonFinnegan]

You guys should make a series out of this and do an episode on explaining exactly how other components work. Ex: gpus, cpus, power supplies, hell even fans. That'd be very informative.

[@sup_3987]

For some reason watching the heat dissipation process is so satisfying.

[@Goodvibesandfood]

Another great video.

[@danieltsss]

Steve your videos ara really good this channel deserves a lot more attention

[@lakicar1989]

Very nice animations Andrew! I wonder how much time it took to render all these out?

[@GamersNexus]

Weeks to render!

good video. I'd really like to know how that X42 does because I'm considering a single 140mm AIO.

[@gucky4717]

I would really like a disassambly for the Be Quiet Silent Loop Pump. since they say its a special kind of pump. They say for example, that the Pump has to run at 100% the whole time (which is around 2300RPM says the Software) or it gets damaged. BUT its more silent then others.

[@wolfpuc2379]

Awesome. Thank you very much

[@ace100hyper3]

Nice!

[@bjorksven]

Nice video, but I hoped to also hear something about optimal mounting of the pump and radiator (e.g. radiator inlet/outlet up or down, etc.) and get that connected to how the things looks inside.

[@GamersNexus]

Jonas Björklund Svensson Not really the point. That becomes a performance test, and we've done that testing before. That said, we're working on more of it

[@mordiggian2730]

In case you work with Blender, you might wanna check out the De-noiser which got added not too long ago with 2.79, its absolute magic what it can do to noisy renders. You might even be able to reduce the samplesize with it

[@gigihpambudi8607]

Thankyou!

[@Venlaw]

HEY, NZXT! FIX YOUR CAM SOFTWARE!

[@sd2go]

does it matter which way the inlet / outlet on the radiator connect?

nice video I don't trust the pumps I'll stay with my noctua cooler push and pull same temps and no risk of killing my cpu ,just my opinion, love you're information video's thank you.

[@thespicyswede9302]

So would I need to fiddle with anything if I were to install one of these all-in-one coolers? Any liquid to deal with or is it place and play so to speak?

[@jt92]

I could have sworn it was the stellaris soundtrack when I first heard it. I can't pinpoint it but I know I've heard that first track somewhere before

[@Malus1531]

+Shahnewaz Ahmed I thought it was pretty low, considering I didn't even notice till I read the comment.

[@sinnison23]

I thought it was fine, just low and subtle enough.

[@tonnysoewito8020]

Nice info, i have question is the pump speed must be at full speed all the time ?

[@DividedStates]

*QUESTION* Isn't the warm water heating the cooled water again on the way back to the outlet? Wouldn't it make more sense to have inlet and outlet on different ends of the radiator or some kind of channel that passes the radiator without heattransfer from the warm inlet?

[@imeverywhereandnowhere56]

I've seen some builds that make their own tubes. And they bend them to the angles they want. Is that a better option? And do those also come in kits?

[@7Tempest]

What should my pump speed be? I don't know much but if the pump speed is max would the liquid not travel in the radiator long enough to reach a good low temperature before going back to the CPU and if I make my pump the lowest speed would it take too long for the cool liquid to travel to the CPU?

[@scottwiltse4081]

Hey Steve when should you change your coolant I have a EKWB 360 extreme with EKWB red coolant cooling my 6700k cpu for a year and a half color looks the same & cpu temperature are great . I pretty much use my computer for gaming BF 4 or BF 1 I was wondering how long the coolant last ?

[@roteroktober360]

water cooler's cpu/gpu blocks should have more surface area on the inside to exchange the heat between the cpu and liquid more efficiently because thats kind of holding the whole thing back

[@fearsomeaustin]

so I have the ENERMAX 240mm AQUAFUSION CPU Cooler, and I'm curious how often I need to drain and refill it. After checking the website it said it requires no maintenance but I can't find any info online.

[@TheJonazas]

Is 35c idle liquid temp and 45c liquid temps normal for x52 on a 4.5ghz 1.32v 5820k? Ambient temps around 22c

[@joeykido1450]

Hey I want to mount a AIO on the side of the O11 Dynamic XL and i'm not sure about the orientation. Basically all builds that I could find put the tubes on the TOP but if i remember correctly, you suggest to put them on the bottom to make sure they never suck air. Are everyone else wrong, or do I miss something important?? Thanks a lot! PS: will you take a look at the Lian Li Galahad AIO?

[@cataria3903]

u should make a video, taking all the nzxt pucks making them into one big magnet and checking if they can destroy an hdd :D

[@aravindraja8034]

Can you please review Corsair H150i Elite Capillex and H115i Elite Capillex

[@sawce846]

Wait so do you need to fill it with water or does it already come with water and you just need to install the AIO???

[@moviingparts]

dig the ambient track in the bg

[@ricardoabh3242]

If more complex what would the recommendations about how to spot a bad product?

[@gagebedaine2533]

Hey pretty dumb question here I bought a pc with one of these in them do I need to put liquid in it or does it come filled or do i need to do anything at all I’m just afraid I’ll turn on my pc and it’ll spray everywhere

[@randomcatontheinternet2771]

im new to water cooling , do i need to refill my water ? or no need?

What about durability? This CLC solutions look great but how long will they work until they run out of liquid? I'd love to cool my next system with a Silent Loop from Be Quiet! but I am afraid of having to replace the cooling solution after that time. Also how rare are leakages from this type of solutions?

[@NZXTglobal]

Our Kraken Series liquid coolers are backed by an industry-leading 6-year warranty. Basically, you don't have to worry about anything in that timeframe. If for some reason the Kraken leaks, we'll replace it along with any hardware it damages.

[@GamersNexus]

NZXT has the basics covered in their answer, but will provide an independent party answer as well: Asetek CLCs tend to start nearing end-of-life by the 5-6 year point, depending on how much abuse they've been through and what kind of environment you live in. The reason for EOL on closed-loop liquid coolers is more because of permeation than anything else; the liquid will begin to permeate the tubes at some point (some tubes handle this better than others), and will do so at a faster pace if liquid temp runs higher for longer periods. The 5-6 year point is when you'll start noticing more air bubbles in the loop (potential "gurgling" noises when the pump starts up on boot), and that's because the loop is starting to lose some of its liquid to permeation (not to leakage).

Well that sort of settles it, I'm going water-cooling in summer. Thx for the super helpful and quick reply, I will consider the X62 ;)

Gamers Nexus I really appreciate you taking the time to answer so in-depth. It really helps a lot, thx

[@1337ghomri]

What is the cube with the hole in the middle?

[@renehoyvik]

Magnet with rubber surfacing from NZXT to hold audio headsets, VR etc. Also has a loop to coil wires around it. It comes with a few of their cases, but can also be bought separately and used on any metallic case.

[@NightOwlGames]

I really want to know how the pump works so far been unlucky had 2 pumps die on me one lasted 2 years the other only lasted 4 weeks. I still have the coolers im wondering if theres a way to repair the pumps especially that one that only lasted 4 weeks I mean it dont make any sense why it broke.

[@koraymustafayasar7671]

Thanks from turkey juses!

[@MLC_corzino]

can i ask if aio cooler its good if i dont water it just fan only.

[@SSS-mp8th]

After I had a CLC die on me after a couple of years I just went with an HSF. I'm sure I could get a 280 or 360 that would lower my CPU temps another 5-10c but with the CPU on the games I play staying under 50c anyway there isn't a point. If you have a mid tower or SFF build then i can see it making sense either visually or due to size constraints. One of the reasons I got a very large case was so I wouldn't need to worry about it. With a cube build like mine all you see is the graphics card anyway.

[@acencollins8597]

for quality and performance is Asus better or corsair for a cpu cooler ?

[@ToxicSHDAgent]

Hello, I have a question concerning my Water-cooling pump. I have bought a gamer pc 3 months ago and I have been hearing a strange noise since 3 weeks. It is like a bubble noise that I never had before. I don't know where it comes from but this bubble noise is irritating. It comes and goes and can last up to 30min. This is the first time I have a water cooled PC. The temperature of the CPU and the GFx card are around 65 to 70 at their peak. There is also the Summer heatwave hitting hard so my room gets hot too. I need advice before I go repairing this. Thank you very much. PS:If you need more technical details about the brand please ask.

[@KChicken]

Is 60c too high for a idle r5 3600 on a x570 with a h100i pro?

[@betrayed1418]

Hi, does missing a percentage of water result in increased temps using AIO? Meaning that after a while I noticed a higher TEMP and I think that some of the cooling liquid got evaporated. Need to know if this could be the cause because I would like to replace my aio's liquid.

[@imeverywhereandnowhere56]

I am wondering about this too. Does the liquid have to be replaced after a while? And do they sell that to consumers in a bottle? How would you go about changing the liquid out?

[@Juan_deep]

I need your help desperately Gamers Nexus. One of my radiator fins snapped off. It was only one small piece i think the metal is still secure on the vertical tubes. This is a radiator connected to my $2200 3090 TI Asus Rog Strix Am i screwed?

[@zergmare7]

Is an aio really worth the liquid risk?

[@GurtTarctor]

Just so happens I was researching AIOs today, if you are in the UK there is a good price for the EVGA 280mm CLC at Scan.co.uk for £90 just now which seems like a really decent deal compared to the competition.
