Hi,

I'm trying to lower the fan speed on my gpu. I used to do it with Ati tray tools but I recently reinstalled Windows 7 and it does not work anymore. I tried Rivatuner which doesn't work also.

I finally that Msi afterburner and fanspeed work, but the minimum fan speed is 50%, which wasn't the case before.

Any ideas?

Thanks

Have you tried flashing the bios?

No. How do I do that?

(Isn't it weird it needs flashing if it worked before?)
