I have crash with bf3 with my new card. Just play about 10-15 minutes, the it crash to desktop while the game was still in taskbar. I'm using latest wqhl driver, and tried to manual control the fan speed, but it didn't help. One thing I notice with this problem is the fan rpm. For example, when fan speed at 70%, the fan rpm didn't stay at 2200rpm all the time. It went down to 1400,1100, then went back to 2xxx rpm. This makes my card hot. furmark about 85 degree.the card is extremely quite. Need help. is it due to my antec green 650w psu problem because with this psu, arctic cooling extreme on my old card can't even run. My new psu will be deliver on Saturday, so I don't know anything to do till Saturday.
