I am in the process of watercooling my bitfenix prodigy, would I be OK running an R9 290x and a 4670k on a single thickish 240 rad (45mm thick)

 

I already have my loop done for the CPU I just need to add in my 290X, People have said you need a 360 rad but a 295x2 runs on a single 120 just fine so presumably a thick 240 rad would be enough for this setup?

a 360mm radiator is normally enough for a high-end gpu + cpu water-cooling setup. Of course more space/thicknesibetter. You should add an extr240mm thick maybe 45mm or 60mm

Ok, 120mm for each component. It is enough.

i normally use as a rule of thumb that a cpu needs 240mm and every component you add needs 120mm,

I dont understand why when you can cool a cpu and overclock perfectly fine on a H80 which is a single 120mm rad

as i said, its just a rule of thumb i generaly use, ofcourse you can get away with less, but thats what i suggest to people, your rad will handle your CPU and GPU just fine, but temps will be rather high on load

perfectly? maybe just enough, but comparing the H80i and H100i is almost no

contest.

 

H80i single fan is 24° warmer than the H100i single fan set (NF-F12)

H80i push/pull is 13° warmer than the H100i single fan set (NF-F12)

i too use the 240 for CPU ands 120 for added GPU/Devices to allow for low fan

speed and low cooling temperatures.
