So what happens when you go into CCC, Graphics, ATI Overdrive, and enable manual fan control? Also, what are your temps and fan speed?
 
Graphics card fan control should be handled completely by the graphics card. If there's no fan control you need to contact the card manufacturer.

I know there is software that can bypass the hardware fan control, but you really want it to be left at the hardware level.

So either your hardware on the graphics card is broken, or the Catalyst Control Center has enabled manual fan control and its set to 100%.

Your temp is OK, but there is something wrong here. My card cannot be heard over the case fans even at 40%. Sounds like your GPU fan may be defective.
