Air is better than water

    • 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.

    • 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, 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)

  • 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.

  • 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

      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.

    • 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.
