Radiator question

yorkshirelad84 · 4 Aug 2009 at 10:30

I'm considering the new Corsair case for a watercool build, i currently have an external watercooling system cooling cpu/gpu, but want to build an internal system,

What i'm wondering is, could i cool both CPU and GPU, using a 360mm top mounted radiator alone? or would i need to also add a 2nd radiator outside of the case? such as a 240mm

depends on the GPU / CPU and level of overclock you are running

AMD phenom 9750 and an ATI 4870, 4870 is clocked at 780mhz and 1090mhz on the memory, and the CPU is stock, 2.6ghz, does that help?

120.3 should be fine - cpu temp will rise with the 4870 in the loop

Yea, i realise that, thats why i wondered if i should have a 2nd rad, 1 external like a 240mm

So it would be

Cpu > 360mm Rad > 4870 > 240mm Rad > back to resevoir

I cooled an overclocked q9550 and an overclocked gtx280 using a 120.2 rad and it was fine

i'm only wondering because i have the zalman reserator XT cooling CPU and GPU, CPU temp is high a lot of the time, where as my GPU temp is very low, i have a 120mm rad in the system aswell, in between the CPU and GPU

Reserator > CPU > 120mm Rad > 4870 > and back to the reserator

Reserator > CPU > 120mm Rad > 4870 > and back to the reserator

The flow order makes no difference. The difference is probably in the GPU block handling the flow rate characteristics of the Zalman better than the CPU block.
