Is two 360mm rads enough for 290x 2 way crossfire + CPU?

post #1 of 7
Thread Starter 
My main aim is to keep my system pretty quiet. Are two EK-CoolStream PE 360mm rads good for 290x 2 way crossfire and CPU? I want to stay below roughly 30 decibels. If I were to add even more radiators would that help much?

Good enough for my 2 970s and i7

Two 360's will supply a good amount of heat dissipation and is enough for 2 290x.

Will using more rads mean my pc could run more quiet? Or have I hit a point where more wont help

2 X 360 is really nice configuration for that GPU Setup. you can run the fans at low rpm.

If you add more the cooling will be a little irrelevant. but if you want to add more rads. don't add thick ones.

^ this

The PE rads perform great at lower RPM, I have them in my build with 1850 vardars @ 1000rpms, although I have a 480+240, but the same amount of Rad space is keeping a 5820k and 2x980s plenty cool.

im not so much interested in the cooling as I am in maximum quietness. I'm planning to use this case www.thermaltake.com.au/products-model.aspx?id=C_00002563 with the two 360mm at top exhaust, and am considering If i should put another radiator somewhere. If you do put a radiator with intake fans thus blowing hotter air into the case would that still lead to better cooling and thus being able to keeps fan RPM even lower?
