Cameron: After installing speccy, it gave a CPU temperature reading between 90-105 degrees C
phaolo: Uh.. random idea, are you sure they weren't somehow 105 degrees F? Such C temperatures are crazy..
I like other Piriform free software, but Speccy just freezes my (old) pc XD
Yes, this was the first thing that came to mind but the temperature is is Celsius.
I downloaded AMD OverDrive as well as SpeedFan and both are in agreement with CoreTemp. It seems Speccy just doesn't give a good CPU reading for me (though it works great on my PCs with Intel CPUs)
Thank you to everyone for your replies, they are much appreciated.
