What SIZE Radiator do you need for Custom Water Cooling?

[@AlainTabangin]

If it can fit in your case then get what can fit. Lol if your thinking about cost on a custom water cooling build, get an AIO, shit will start getting pretty expensive once’s you start adding blocks and fittings. That’s why I wait like 5 years to upgrade to a new build cause I will just go all out. My previous all out build was fully water cooled 980ti in sli configuration with Intel 4790k. Now my current build is 4090 with an amd 7950x3d that is being cooled by 420mm rad, 280mm rad, and a 120mm rad. Get what fits and not worry about until your next upgrade cycle.

You've forgotten the OP 480mm radiator size... Which you only use when you're trying to show off. 😂

Your right! Got dual 480s on our editing system, finding a case big enough can be rough :)

i think 360 is too tight for rtx4090+13900ks^^

[@fluixtech]

Yea I hear ya, that would be over 600 watts at peak power. Still doable with a 360, but having a 240 on each is bear minimum with optimized fans and a high flow rate pump! With rads I tend to go overkill, our 12900K and 3090 system has dual 480s.

There's a lot more factors to it than just size. Fin density, rad thickness, static pressure all play a factor in how effective a loop is.
