It depends on the video card. There are many video cards out there that use only two wires (+ & -). There is no way to read the fan speed on those cards.

My guess is that the fan on the graphics card doesn't have a rpm sensor. The fan controller still works, but the fan can't report its rpm.

My guess is that since the fan doesn't have a rpm wire, the manufacturer didn't bother to change the fan profile in the bios. Maybe the fan profile in the (card's) BIOS is for PWM fans only. Since your fan isn't PWM, there was no need to change those values, so it was left at 30%.

have u tried MSI Afterburner to see if it can tell u the rpm of ur fan?
bcs if that program can't either it can be that ur fan on ur gfx don't support that feature and fucks up the reading of gpu-z ^^;

Then you have a laptop, don't you?
Then probably the cooling inside the thing is like on this schematic:
So the chips in your computer are cooled by leading various heatpipes from them to one or two system fans.

Yes.

I don't understand what the diagram has to do with my fan speed though. Now I'm guessing its GPU-Z that isn't correctly reporting the speed because it says its constantly at 30% even when its audibly idle.
Is there any other software I can use to monitor fan speed? Speedfan, RivaTuner, EVGA and MSI Afterburner aren't compatible.

My point was that there is no seperate GPU fan, only a system fan. GPU-z does not seem to "understand" this. Better try Hardwaremonitor: http://www.cpuid.com/softwares/hwmonitor.html It will show the rpm of the laptop fan most likely under the name "system fan".
