I cant find where the sensor 4 "Memory Heatsink" are placed on a mac G5 / late 2004 / 2,5 GHZ.

WHERE CAN I FIND SOFTWHARE 4 CALIBRATE THE SENSOR, its showing 20 DEGR TO HIGH temperature.

IF SENSOR Is ON some cind of cabel, mabee it has been placed wrong, under the warmer part, near the processor.

FAN NOISE - IS THE COMMON REASON 4 ASK.
