err guys..got some prob...about the fan

on auto setting(monitor by GPU-z)...when the temp reach 80'....the fan should run at 70% of it speed rite....the prob is only the GPU-z said so...the fan at the gfx still running at lower speed...how to fix this...

i have to set manual 70%...cannot set auto...if not the temp will reach 90' on load...coz the fan still running at lower speed no matter what's the temp...not following the rate it suppose to be...

auto      > idle 57-58 load 87-90 (CPU-z show the fan running at 85% but actually not...no noise at the fan n silent)
fix 70% > idle 43-45 load 63-65 (i can hear the noise of the fan running at high speed)

the card already flash by fix bios (10.071)...still same...is there any latest update bios??? I found 10.077..anyone test it??

You fixed the fan ur self. Download the ati bios editor and change the fan setting to temp=42 and steepness=52. Advisable to use ur OWN ori bios to mod. Now idling at 51c and under load at 70-75c.
