Hello, i have an XFX HD5670.
The blower fan died, so I took the shroud and fan off. I attached a Delta 80mm fan to the heatsync and it does a good job of cooling it as it runs around 20-25c cooler in games and no longer throttles to death.
However, the default minimum fan speed is 25%. With this new fan, if the fan speed is anything under 40% or so (so all the time at idle) the card makes an odd beeping noise. Setting the fan speed to 40% or greater makes this noise go away.
What is this noise caused by? Can i fix it other than ramping up fan speed?
