Was having a little problem with my XFX 7900GS 600M. Hope u guys can help! The card is clocked at 600 mhz as opposed to 450mhz on stock 7900gs. So it runs quite hot. whenever i play games i have to manually incr the speed of the fan using ntune. but the fan speed usually rolls back when i launch games such as crysis. how can i acheive contant fan speed in such circumstances?
