i fit an S3 fan but the temperature rise 10º one blade goes from 52º to 64º the other blade goes from 64º to 74º the fan was extracting air.
this dont make sense to me. Can someone explain why
If you fit an S3 fan and you are overclocking, you'll have to do the blue-wire hack, i.e disconnect the blue wire to have it running at full pelt as having it controlled by the bizzare S5 PWM firmware will simply muck your efforts up.
Yes, i just connect the fan directly to psu 12v.
After a few tests i think i already understand the problem. The heatsink is not very hot but the board is very very hot so the temp sensor is very hot. We need to remove the hot from the board so We need to fit some heatsink in the back of the chip (back of the board).
