I'm running an AMD 5900X, Gigabyte X570 AORUS ULTRA motherboard and a be quiet! Silent Loop 2 360 High Performance CPU Water Cooler
Over the weekend I noticed that the CPU cooler fans were spinning up frequently and getting quite noisy while sitting on the desktop (with just Chrome and Firefox open but minimised), not something it had been doing before.
In this fairly idle state, CPU temp was going going up and down a lot, moving between ~65c and up to ~80c (even the odd spike to 90c at one point). During this, CPU utilisation was around 5 to 10%, however 1 core was often around 100% utilisation. I tracked that usage to a Microsoft search process and killed it, however even at virtually no CPU utilisation the temps were still going up to the ~75c regularly.
Even when the CPU was showing 90c temps, the air coming out of the radiator was still cold (not even warm)
Based on what is happening, my guess is that it could be one of two issues:
AIO cooler pump is not pumping correctly, therefore not removing heat effectively (I checked the 'fan speed' for the pump via Open Hardware Monitor the rate looked normal, though can't remember off the top of my head what it was... ~2500rpnm maybe?)
or
The CPU temperature sensor is not correct, resulting the fan curve kicking in when it's not really needed.
Based on the air being cold coming out of the AIO radiator and the fact that other temp readings (Core Average and CPU package) were barely over 60c when main temp sensor was reporting 75c, I'm leaning towards the issue being the sensor, even though I'd would expect that the the likelyhood of the AIO pump failing is probably much more likely than a temp sensor failure.
Does anyone have any experience of this behaviour, or any suggestions of other things to check?
