Biatche, I'm amazed that you don't have geforce experience installed since that is the program used to update the firmware and DRIVERS of your graphics card. If you plan on playing any pc games newer than 2006, you might want to consider installing it. Try updating the firmware and drivers of your graphics card with it, maybe it would be a little more co-operative with hwinfo.
Martin, Since your latest beta build, CPU and GPU always show up but the fans don't actually begin to move until i open the fan settings (clicking the little fan icon). Once that window is open, the fans start to move. I can minimize it after and the fans still operate but if i just boot up my pc (hwinfo set to auto boot up too) and leave it at that instead of opening the fan settings, the fans never turn on (i'm guessing it is the sleeping gpu thing). But once I click the fan settings, the fan control kicks in and stays
. I also have 'wake sleeping GPUs extended' on maybe that helps it. Not a big issue, having to open the settings every time, its only 2 clicks, but it is a nuisance if i forget to do it.
