Hehe, buggy motherboard sensor Sensors tend to become just a liiiiittle bit innacurate with the extremes.
As far as I can tell, that's not your GPU temperature. That slider tells you what the maximum fan speed setting you want. Set to how it is, your fan will go at 100% speed if your GPU should hit 101c. Trust me, if your GPU was at 101c right now, you wouldn't be able to read this text due to artifacting... if you somehow managed to get your PC to boot with those temps.
It says the same. I know the sensor is faulty, I can touch the GPU heatsink and not burn my hand off.
