Is water cooling ever necessary?

post #1 of 21
Thread Starter 
I don't really know anything about cooling, but I was curious if there is a point in CPU or GPU power where air cooling is just not viable. For example, if I do quad-SLI, can it still be cooled with air? And by cooled with air, I don't mean like "jet engine" or anything. Can it be cooled without having a case made out of fans?

Just curious, thanks for any input.

Watercooling usually gets better temps than air cooling.

For quad SLI, with air it will be VERY hot probably with 4 gpus next to each other. Im sure you can air cool it, but with not-so-good temps.


Watercooling looks cool, its usually fun to do, but it costs more than air cooling.

Allows for more overclocking ability, and cooler temps.

Simple answer: No

Definitely not "necessary", depending on your preferences. Some people are comfortable at certain temps than others.

Everything can be air cooled, every setup, no matter what... How hot it will get, well that's a chance you have to take.

Necessary?

Eh supercomputers probably.

probably quieter than air cooling as well, but i dont think it is necessary. more like a luxury.

Nope, not necessary, more like a luxury. However, if your looking to water cool gpus and you have the money, do it. You will be far more impressed with gpu overclocking on water than you will with cpu overclocking on water.

water cooling can pull more heat faster away from components, it IS necessary if you are pushing your equipment way beyond spec, have very high ambient or have a very small enclosure where large heatsinks are not an option...

with the right equipment you could squeeze a quad SLI setup into an enclosure a little larger than your average full sized laptop... and still keep it cool enough to last...

in the 5ghz+ range it is almost always required...

Everything that has been said is correct. The biggest benefit in my mind is that I can have high overclocks, cool temperatures and a very quiet computer. This wasn't possible when I had an air cooled rig.
It didn't come cheaply or without hassles though. If you are considering it, I would start with an all-in-one cpu cooler from either Corsair or Antec.
