High fluctuations in CPU temp

[Assoul]

Hello,


I installed my CPU last week with a Noctua NH-D14. I used about a pea-sized amount of thermal paste that came with the Noctua and mounted the fan on top of that the best I could, but I may have smeared some of it around the CPU heat spreader since it wasn't perfectly above it when installing. I screwed the mounting bracket in by hand and then used a power drill on a very low torque setting to tighten it.

About a week later, I'm looking at my CPU temperatures in HWMonitor and, at idle, the CPU temps fluctuate from a low of 17C to a high of 46C, and the real-time reading jumps all over the place.

Any thoughts? I'm running an AMD-8350.


Thanks.

It's normal for temperatures to fluctuate when sitting idle on the Windows desktop, because various things will be running in the background, using CPU cycles.

46c is definitely not concerning.

17C seems very unlikely to me?

AMD sensors are not calibrated. So whatever they report is meaningless in terms of compare to anything else than their internal table.

They could just as well report in bananas.
