Today everything was fine then all of a sudden my motherboard temp
as reported on Speedfan 4.32 went from 35 to 40C to108C. I opened up PC Probe for comparison and its reports 147C. They normally reports fairly similar temps. I opened up the case and everything seems to be fine. Any Thoughts?

Thanks
