Radeon HD4870 fan control

[TheSilencer]

Hi!

I got an MP09 with Apple HD 4870 512MB graphics card some time ago and while I enjoy working with Mac OS, I also enjoy playing games. At the Mac OS side I don´t really play games or do much heavy 3D stuff but on the Windows side then I play. I noticed that the graphics card kinda get´s hot, not in amounts to worry but still.

Catalyst Control Center states the following: 79°C while at 70% load with fan at 20%
Windows 7 x64, Catalyst 9.12

I would like to tune the fan to 33%. Is there a way to do this? I enabled Overdrive and checked manual fan speed, which doesn´t work (known bug). Then I edited an profile and loaded it, still not at 33% fan speed.
I also tried Speedfan to tune the PCI fan of the MP but it doesn´t show me the fans of the MP.

Any suggestions on this?

Thanks!

Sounds like you need SMC Fan Control.

Any settings you save under OS X will be applicable under Windows, too.

doesn't work on GPU fans.

If, however, you look at VERY FIRST POST in the giganto 4870 thread, the answer is there.

Well, flashing the card isn´t the option I look for and I don´t want to break the Apple CPP.

Any other software based solution?
