Ive recently had to rebuild my mining PC:
1x XFX 5850
AMD 12.2 driver
Im mining fine with cgminer but after around 15mins the fan speed will drop back to 56% for a couple of seconds before jumping back to the % I have it set at (90%), this then jumps back and forth every 5 minutes or so.
Ive uninstalled CCC leaving just the driver, ive flashed the cards bios to try and force the fan speed that way and ive also set the speed with MSI Afterburner, all with the same outcome.
Is this a known bug with the 12.2 driver?
Thanks for your time,
