With Opensuse Tumbleweed (20211116) installed I get temperature readings jumping from say 34c to 84c and then back to 34c. I logged it and it would stay at a normal lower temp (30c or so) and then spike for 84c for 10 to 80 seconds before jumping back to the lower temp, no pattern I could see. There was no temperature transition in-between the 84c and the normal temperature. It did not feel hot to the touch when it was logging 84c. Very low disk activity during logging. The MB is an Asus X570P
I have a Samsung 970 with win11 on the same machine. No problem with spiking. I installed Opensuse Leap 15.3 on the 980 and did not see the spiking problem. I decided to migrate the win11 os to the 980 and install Tumbleweed on the 970. Tumbleweed is not spiking to 84c on the 970 and I don’t see any spiking on the 980 with windows.
I’m thinking it is a software problem and not a temperature problem.
I posted this info on the Samsung site in reply to someone else who noticed this and decided to post it here to get more linux eyes on it and see if someone knows what could be happening with this temperature reading problem. It seems it is happening on the latest Arch installs also.
Hmm temp rise goes with usage.Which temp are you monitoring??? CPU/GPU? Maybe run top to see what application/process is putting on the load. I see high GPU temp when I run Windows in VBox and it decides to do an update
That is what I thought. I added heat sinks and blew a fan on the drives and it did not make any difference.
It is a sudden jump to 84c with very little disk activity and they feel cool to the touch. There is no gradual rise to
the 84c temperature it just starts reporting it. Like this test every 10 seconds.
This is the current output of [FONT=monospace]sudo nvme smart-log /dev/nvme0n1p3 with the cooling off so it does help.
Temperature Sensor 1 : 39 C (312 Kelvin)
Temperature Sensor 2 : 49 C (322 Kelvin)
Thermal Management T1 Trans Count : 0
Thermal Management T2 Trans Count : 374
Thermal Management T1 Total Time : 0
Thermal Management T2 Total Time : 1326
I solved it by running windows on the 980 and Linux on the 970. The 970 does not have this problem for me.
The problem is now being reported by another on a 1tb Samsung 980 drive with Debian Kernel 5.14. Always
a sudden reported spike to 84c.
Again, thank you for taking you time to suggest a solution.
