    Hi !

    Does anyone know which Chip on the 5850 Extreme from Sapphire is doing the fan regulation ?

    My fan is always at 100% and I can't even read out the RPM's anymore.. Looks like there is no pwm fan .... like on the very old cards.

    I think it must be an IC or an Resistor or so which broke, I saw nothing special in the near of the pwm connector.. The connector also is correctly in place and the fan also works flawless (at 100%). I tried an other 4-pin pwm fan, same problem persists.
