Inconsistent CPU temperatures

DevPete · 1 Jul 2023 at 21:38

I'm using the Gigabyte AORUS System Information Viewer for my Gigabyte motherboard and trying to configure the fan curves. I've noticed that the CPU temperatures in this tool don't match what is in the Ryzen Master tool :confused:

Any ideas why? For example, I have a screenshot with 49.37C in Ryzen Master and 62C in SIV.

I'm finding that the fan keeps spin up to high speeds and then spinning down. If I ramp up the fan curve, then it becomes very noisy at idle. Given that Ryzen Master is showing less than 50C, it doesn't look like it needs more fan speed. Case temperatures are between 33C and 36C. GPU temperature is around 45C (at idle).

I never noticed this problem previously and all I've done is upgraded the GPU (this will make things a little warmer), removed one case fan, moved it to another room, and done a clean install of Windows 11. I might try adding another case fan although I'm not sure that the extra fan was useful.

One of them might be referencing a different sensor or might simply be miss reporting.

I'd suggest downloading coretemp or HWmonitor and see what temps they report.

I switched it back to the normal mode at the end and it all settled down. I think Windows was doing indexing and updates etc. as it was a fresh system. Once that stopped the temperatures dropped by about 5C and the fans were ok.

I'm getting BSOD all the time now though (not temperature/fan related) :mad:

Run a benchmark like Cinebench R23 & use CoreTemp to monitor the actual temperatures from the CPU. You should be able to also have RyzenMaster or HWINFO64 sensors open at same time to see which one is reporting the correct values (just noticed that this has been mentioned a couple of posts above as well). Also set the fan curve you want from directly within the BIOS of your board if the fans are connected directly to the motherboard fan headers rather than a piece of software (ensure that the fan headers are set to PWM rather than DC unless using a separate fan controller where you may have to set the curves in that instead (ie like Corsair iCUE is required for full control of fans connected to a Commander Pro etc)
