It is the fan on the graphics card itself. It starts when the computer boots, but can settle down after some time. It's obviously not a fault, but just a matter of some wear, on a 2 year old card.
The catalyst control centre lets me instruct the fan speed to go to anywhere between 20% and 100%.
Now, I have a sensitive nozzle for an air compressor, which I have used to blow out the microdust that can and does accrue in the fan.
It may simply be related to the ball bearings, but I don't see an inlet to add any lubrication oil or graphite, and don't want to begin attempting to unscrew and disaassemble my removed graphics card.
-I'm simply wondering, is there any further way to instruct the speed of the fan any lower that 20%, maybe even 15, 12, 10 (and even 0), in such a way that it will ignore this speed and go faster for heat protection's sake, if required? Is there some sub executable that the catalyst control centre places which might give me this option? Failing that, can someone point me to a free, safe little program which is catalyst copatible and will fulfill my requirements? This would definitely put my whirring problem firmly under my control.
I'm running 64 bit Windows 7 Home Premium.
Can someone kindly respond to my posted questions here?
