    Can't monitor the fan speed of the GTX 460M on G73JW

    I've been trying to read the fan speeds of the GPU on my G73W with an NVIDIA GTX 460M, but all the apps I've tried to read show 0% use. The fan is working, but even when I use MSI Kombuster 2.4.2 to load the GPU and use MSI Afterburner 2.2.4 to monitor the GPU I can see the status of the temperature, Memory use, loads etc, but the fan speed remains at 0 even when GPU fan revs up during high loads. The graph for the fan is a flat line. Maybe I'm missing some applications or driver that allows applications to monitor the fan speed. I just tried the simple GPU Meter Windows Gadget with its companion application (PC Monitor) and the fan speed still show 0% use. Any suggestions?

    Have you tried using hwinfo64? If not I recommend trying it on sensors mode.

    I just removed an old version of HWiNFO32 and installed HWiNFO64 4.04. As I look at the sensors status page it shows the GPU Fan as: Current: 100%, Min: 100% and Max:100% - I also used the NVIDIA Inspector->Sensor Monitoring and it shows the GPU0 Fan Level at 0% with a Min: 0% and Max: 0% - The graph history shows a flat green line at 0%. This while I can hear the fan speed up as I increase loads with MSI Kombustor. While using HWiNFO64 what's the current percentage on your laptop while it sits idle? Can the fan sensor be disconnected somewhere?

    Don't have a G73, I actually have a G75 and hwinfo64 works perfectly to tell me how fast the CPU & GPU fans are running. It displays the readings by RPM on the G75, that's why I recommended trying hwinfo64.

    What version of NVIDIA drivers are you using? I'm using 306.23 the latest WHQL release.

    Using the same one. No many drivers have been released that have support for the 660m keplar card some of the G75's comes with. Other than the stock driver on the ASUS support page and the recent 306.23 WHQL, there have been maybe 3 beta drivers with support for the 660m. So I don't have many options when it comes to display drivers, yet that is, lol.
