Hi. I've got an nVidia GeForce GT 220 GPU on my tower PC. When playing games, the fan is not going to speed up. Only the CPU fan is speeding up. I tried changing the speeds manually but nothing happened. Here is a list of the programs I tried: nVidia Control Panel MSI Afterburner RivaTuner Performance(nVidia) SpeedFan ASUS GPU Tweak Only SpeedFan was able to monitor the fan speeds, but it wasn't able to change them!. When I tried to speed up the fans to 100%, they were still low! Please note that I can't buy a fan controller!
