CPU cooling
Swiftech Apogee XT Extreme Waterblock
CPU Idle temps are 28* C
CPU Load temps are 72*C
GPU cooling
HeatKiller GPU-X Full Copper blocks
H20 Cooled GTX570 Idle is 32* C and load is 47*C
Twin Frozr II GTX570 idle is 31* C and load is 68*C
Twin Frozr GTS250 isle is 36*C and load is 72*C (used as dedicated physX)





I have since pushed these cards to 1.1v, coreclock of 945MHz, shader clock of 1890MHz, and a mem clock of 2300 MHz.
I am going to be adding a waterblock to my second 570 as well as adding another 360mm rad in the mix. One rad will cool CPU the other rad will cool the GPUs. Mind you my temps are me being overclocked also. Not stock.
