I can only let my gpu fan run to a maximum of 85 % although it’s at 90 Degrees. Tried with MSI Afterburner but same 85% barrier.
Can anybody help me?

I am new here on this Forum sorry. My system is a i7 860 with 8 gb ddr3 ram and a gtx 680 graphics card. Here is a screenshit of MSI Afterburner not letting me increase the fan speed. My fan is a arctic accelero III. Thank you for your quick response! :)

Doing some research, it seems like a vBIOS limitation to fan RPM, not strictly a %.

Whatever 85% represents in terms of RPM (can be viewed in software) is the upper end the vBIOS allows - same with the lower end.

A vBIOS flash might allow the fan to spin a bit faster, but chances are there's a reason for such a limitation.

You're likely to achieve better results in cleaning out the card of dust and a reapply of the thermal paste.

I second cleaning things up a bit. Your system is a bit aged and the thermal paste on your gpu fan is probably needing to be replaced if it hasn't been done in the past couple of years.
