It's entirely likely the fan cannot be adjusted.
Power down the system and take a look at the card, if there is two wires going to the fan the speed s fixed, if it has three you should be able to change it.
The above user would almost certainly be correct then. The cards fan is not designed to be controlled. Past of the cost cutting for lower end cards.
You bring up an interesting point. I almost forgot about the lack of speed control on some lower end cards.
All my low end cards are passive : )
Does the card even show a speed in afterburner?
Technically 2 pin fans can be controlled with voltage, but maybe they never did that for video cards.
Good catch coozie7
No. The afterburner does not show the fan speed. I am not planning on keeping this card for too much longer. I just need it for a few weeks until I'm debt-free. Then an upgrade will be coming.
The msiafterburner states that the GPU is running at 59`c. whilst converting black ops on steam.
I don't really recall these temps with my 6450. I recall idle at around 30 - 35`c.
However, The fans on the 6450 were set to 100%
