Intel 9920x temps reported wrong?

[Thingomy]

I have recently built a machine with an i9 9920x with Asus prime x299-a and a pair of RTX2070s.

 

The machine is to be used for heavy, long duration render jobs using cuda, hence the dual graphics cards that don't normally work together.

 

The machine is working great, and informal benchmarking puts it 3 times faster that our other graphics workstations for some real world workloads.

 

Only I'm moderately concerned about CPU temp reporting -- when I fired up speedfan a few minutes ago, it reported light workload CPU temps of about 11c -- Noctua air coolers are good, but getting more than 5c sub ambiant isn't really a thing, so it looks to me as if something is clearly wrong with the reporting here.

 

I'm currently running furmark; prime95 and a render job on the other GPU and the temps have stabilised at CPU 70c-75c (read off the speedfan graphs) and GPUs 73 and 56 respectively (read off furmark)

 

Thoughts?

I've gotten weird results with SpeedFan in the past, try HWiNFO64 and read the temperature sensor data from there. If its still the same I'd suspect a busted temp sensor. Probably nothing to worry about, but you could try to RMA if it worries you.
