Look at the spec from Ati and you can see the idle power consumption.
Idle Gpu clock speed at 157Mhz and with CF(2cards) total power consumption range from 150watts to 350plus, with Cpu i750 OC at 4Ghz. Using 3pins energy monitor to check the wattage consumption.

With single card 5850 and i750 at 4Ghz on water-cooling. Is a real cool power card at its performance.
At 4.2Ghz.
Now 5850 x2 at 4.3Ghz.
We tried to push further but managed only 29k, using Ati gpu clock we push to 1000Mhz/1200Mhz memory....
bottle neck by cpu clock...not cold enough that's why i said simplified single stage...Coretemp around -12 to +12...SS showed -30 to -39. But is good enough for a start...keke.
