Got to love that condensation that will happen in the PC
At last instance...
It's definitely easier, simpler and cheaper.
Water cooling can be quieter, though. Some big radiators and you can cool a gaming PC with hardly any airflow.
Nothing like a gamer sandwich
I like not having to worry about a leak destroying all my expensive hardware.
I once had a PC with watercooling. It died because I was drinking with a friend and wanted to show it off. So I removed the sidepanel and my drunken self tipped the beer bottle which promptly spilled over the running mainboard. Welp, it was some form of water that killed my PC I guess.
I think it depends on the use case. Personally, I simply don't jive with the idea of conductive liquids swirling inside my expensive PC.
You're supposed to use distilled water which is not conductive. At least that used to be the case last I saw liquid cooling.
In the end it's simply not worth it for me. You still need to radiate the heat out, which usually means a big fan, which most air coolers nowadays have anyways.
Liquid coolers are by definition just an extra heat exchange step unless you're venting heat into the ocean or something like a nuclear plant. Otherwise, the atmosphere is your final heat sink either way.
Unless a liquid cooling radiator is significantly larger than the air cooler that would fit directly on the CPU there's no point whatsoever.
there’s no point whatsoever
I've been building my own PCs for a looong time, and I've been skeptical of using water cooling in any of my machines.
This changed recently for me, when I got my first 4000 series nvidia gpu, that fucker is huge! And it runs hot, spewing all of its heat directly into the middle of the case. I had serious concerns with this gpu + massive cpu air cooler getting in the way of positive airflow through my case.
And this is where water cooling made perfect sense to me: transport the heat away from the cpu, thus clearing a ton of space from the middle of the case, then have a radiator at the top of the case dissipate that cpu heat.
This allows for a ton of air to go through my case, evacuating all of that heat blowing out of the gpu. This also allows for other heat sinks on the mobo and other components to passively cool better
I agree with you in most cases.
There is a point though as a water cooler can cool an extremely small area better than heatpipes. Look at Zen 4 processors for instance. The CCD is so small and offset that many air coolers don't properly line the heat pipes with part of the CPU making the most heat. Because of this Noctua even makes and sells an offset bracket to try and move the heatpipes over the CCD. Meanwhile a waterblock should cool the entire area at effectively the same rate as it doesn't rely on vaporizing the coolant and condensing but just pushing coolant through regardless of heat saturation.
Only a fraction of people should really notice that like overclockers and generally people buy coolers they don't need.
I think water is rather rare as a coolant these days. Organics (chemical sense not farming sense) like propylene glycol or some kind of glyme aren't potentially corrosive to metals if spilled, are harder to grow shit in, have lower volatility, and have a higher thermal limit. Maybe also with a little bit of antifouling agent thrown in. My main gripe with them is that if you do spill them, they don't evaporate and you're slipping over the floor for the next few days because you missed a spot.
But yeah, air cooling ftw
It's a fun thing to do. I like my setup (O11 dynamic XL, two 360mm rads, dual pumps, both CPU and GPU blocks), but I wouldn't necessarily recommend it to anyone. It's a lot of effort and expense for a little gain. But it's a hobby on top of a hobby, and that's fine if you want to go for it.
Yes thank you. I went through a water cooling phase, what a pain in the ass. Worrying about the pump, algae, topping off reservoir, leaks ruining your motherboard. The concept is nice, but the reality is high fucking maintenance for no added value.
Not necessarily, but one, it's a lot cheaper, two, air leaks are not a problem.
the bigger the air leak the better the cooling 🗿
Yes, this is the best argument in favor of air cooling. Air cooling has less points of failure.
With water cooling there's tons of potential problems that "haha wind go brrrr cooling" just doesn't produce: Water block gummed up with mold? Take a performance hit. Pump dead? Sucks to be you. Leak in the system? Enjoy replacing your motherboard.
Main issue you might encounter in air cooling is just "fan died, replace fan". (Obviously not counting thermal interface materials since they are required for both cooling solutions)
Air cooling has less points of failure.
One of the main reasons why brand name workstations and servers are still air cooled... and will probably be for a very long time.
There are some data centers that are water cooled though. I know OVH uses water cooling for some of its servers, and also seems to be developing immersion cooling.
Finally, there's water in the cloud 😂.
yea but whatercooling is a complete new space in the whole building process, when building alone gets boring it opens a whole new door to customization, dedication and „learning“ (its not a really usefull skill), but if its something that pleases you, its just freakin cool, even tho it sucks compared to air cooling its a huge subspace in the custom pc scene. its an enthusiast thing for people who are a bit freaky :) i love it and im always happy when i look at my machine
Quieter, less point's of failure, and in many cases taking up less space. I have compressed air for dust. In the consumer sphere and almost any enthusiast sphere, air cooling > > > water cooling
The only downside really is RAM slot clearance when you need a beefier air cooler.
Just bought one of those brown monsters for a new build, can't wait to try it
Noctua master race
NH-D15 supremacy
I love the sound of jet engines during morning boot-up.
I didn't know they even made a three-phase computer fan. That's nuts.
Cries in SFFPCs
Hard to tame a 5800X3D in a 8L case
I literally just installed an NHD-15 and it dropped my idle temps 10 degrees vs my old AIO. Load temps are about 5-10 degrees cooler, too.
IMO, if you aren't using at least a 360mm radiator there's not a lot of point water cooling.
The point of water cooling is that you can transfer the heat from the heat producing component out to a large surface area by physically moving the hot liquid. 2x 360mm radiators give you a ton of cooling capacity. 1x 240mm? You can do almost as well for much less money with a really nice air cooler.
I'd also offer that it allows you to dump all the heat outside the case and avoid warming other components (assuming you put the radiator on an exhaust fan). This is a benefit with any size of radiator.
Didn’t Linus tech tips do a video on this and find that water cooling doesn’t make much if any difference.
I wouldn't cite LTT for much, but IIRC, that was only true to a point. The NHD-15 is great, but a lot of cases can't fit one. Same with many other high end air coolers. It might also cool to the same temperature, but is also running the fans harder to get there.
Like i give a fuck what cools best. I want my system to look awesome and the AIO sure looks better imo. At the end of the day: build the PC that makes you happy.
Some suggestions here, the first a good GPU that can run Cyberpunk or the Witcher III at 300 FPS

Water cooling feels unnecessary and expensive. Like most of my hobbies. I don't get this particular one, but I can appreciate why people might.
The only reason I have water cooling is that I bought my pc used and it came with water cooling. I'm too lazy to change it. At least the RGB lights on the motherboard were switched off with a simple toggle in the BIOS.
My GPU had a shitty blower cooler, switching to water-cooling made my system so much more quiet!
I don't understand why they sell GPUs for up to $2000, and they still come with the same crappy fans we had on $150 cards.
Want watercooling? Have fun invalidating your warranty.
I don't follow. The cooler designs on modern midrange and high end GPUs are way bigger and more elaborate than anything that has ever shipped on a $150 GPU.
Small form factor computers are a lot easier with water cooling. That way the GPU can be put right next to the motherboard, and the CPU radiator moved away from that area.
Eeeehhh it's about on par
The biggest bottleneck on both of them these days is getting the heat away from the cpu and into the cooler fast enough. Unless you're de-lidding your cpu, using a peltier or some other lower than ambient powered cooling theres probably a negligible amount in it.
Welcome to brown town population cool
Yes this correct. I always use air cooling for my self and clients computer builds. With water cooling, you are asking for trouble.
The problem with Noctua is that you need a lot of space...
