Here is my setup:
-12"x5" Hayden trans cooler
-(2) 120mm fans at 85cfm each at 12v
-BeCool "maze" copper block
-Danner 350 Magdrive pump
-3/8" fittings throughout
-water with 10% antifreeze mix
-ambient temps of 24c
With an 81 watt load (1.0ghz at 1.21ghz with 2 volt core) I am still hitting temps of
41c-42c under an extended load. I have good water flow, the block has thermal grease on it, and there is PLENTY of airflow in the case and through the radiator. I have also checked for a square fit on the block /cpu interface and it seems perfect! If I turn the fans down to 10v for quietness, I hit temps of 44c.
Where am I getting this high temp? At that temp, my effective C/W is only in the .21 range, rather high for a water cooling setup.
Something seems amiss....not too mention at LANS the ambient temp is often in the 27c-29c range an that puts me in the 45c-48c on the cpu temp and I just don't like that at all.
I am at 100% perfect stability, but my temps seem a bit to the high side, even at the wattage I am pushing. Any suggestions?
P.S.---the water goes from pump to radiator, to reservoir, to waterblock, and back to pump. Pump is inline closed loop, so no heat from pump is contaminating the results. See the pics at
