Question What's the optimal fan curve for a 6650 XT using AMD Radeon software ?

[Westley The questionnair.]

Just wondering!

Whatever floats your temperature vs noise boat.

Just like any other, max revs before maximum hotspot temperature is reached. Default fan default starting speed is usually about 50c and letting them start earlier or turn faster is of no benefit. So, just a straight line between starting and hotspot temps would be indistinguishable from any other variations.

It mostly depends on how good the cooler is. If the cooler is good, you can just leave it to default and call it a day. If you are getting high temps under normal use, then do as CountMike says. If it gets too hot and throttles, then you should underclock and undervolt it.

I have undervolted it, but whenever i restart my PC, the GPU profile goes back to default.

Optimal is a subjective measure and depends on multiple factors, particularly your system's cooling/airflow setup. whether OCing, how much noise can you tolerate, etc.

Except for the most extreme of circumstances, you should not have to underclock/undervolt to maintain sufficient cooling.

With everything at stock settings, what are your CPU and GPU operating temperatures at idle and under load?
