I was testing out some overclocking on my Ryzen 1700 system. Had a crash while stability testing, but when the system rebooted I found that the motherboard CPU temp sensor was stuck at 42c. The actual CPU diode sensor (Tdie) is functioning correctly, going up and down as it should. But the motherboard sensor just stays frozen at 42c.
Any idea's how this could be fixed? I was trying some pretty mild overclocking, so I can't think I fried anything by mistake.
