Ive been reading some articles about stuck temp sensors as I'm not sure if mine qualifies as stuck or I'm missing something. I think its possible core 1 is stuck as i haven't seen it drop any lower the 41c but using Real Temp Cool Down Test the cores are always within at least a degree of each other, Ive attached a picture below.
The fact it doesn't drop below 41 has probably more to do with a bad heatsink/airflow than a stuck temp sensor.
Make sure you have appropriate airflow in the case by routing cables away from the area around the cpu. Also clear any dust from the heatsink.
It's not stuck...?
One CPU core will typically be favoured, and do more work.
41C at idle is good, that's really low...
The internal core temps are actually always higher than the single 'external' CPU temp reported, anyway.
So it's that 32C core temp that is actually suspicious!
Lemee see now, an E6420 @ 2.4GHz I have running here is ~53C right now (doing stuff) and each core is reporting ~56C...
I've never heard of a stuck temp gauge before,
There is such thing, search the internet and you will see its quite common with the newer 45nm intel processors. Also it shouldnt be that suspicious, im using speedstep so the processor drops its voltage while idle and the multiplier drops to X6
