My MOBO seems to be reading the wrong CPU temperature (sensor issues)
Hi, all.
Before I start, my CPU is an A8-5600K and the mobo is FM2A75M-DGS. What I think is happening is the mobo is reading the CPU socket temp where it should be reading the core and/or package temp.
So, a while ago I was having some CPU overheating issues so bought a new cooler and all is well now. Tonight I decided to play around with my fan control and used my mobo utility program.
Here's my issue. In this pic you can see a comparison between the utility and HWiNFO64. My mobo is going by the green ~25C temperature, but there's also the temp marked in red, which is the same one I get in Speccy and my Afterburner overlay when playing games.
I started adjusting this a couple of days ago when I set up my fan control in BIOS and then noticed that the CPU fan never got louder, not even while playing a game and the overlay was showing temps at around ~68C which is way over my set 45 one after which the fan should kick it up a notch or two. I then switched it back to full power and the temp readings normalized.
So, going back to today, I decided to do the same thing in the utility program and find it hard to believe that my CPU temp is 25C with room temperature of around 22 and a bunch of programs open. Not to mention my case which is terrible airflow-wise. The temp also didn't change at all in a period of about 5 minutes, when normally CPU temps keep changing, even if just a little.
Basically, I'm just looking for confirmation that the bios/mobo readings are wrong and I should run my fan at full speed instead of trusting my mobo to properly control it.
I ordered a new case that comes with a fan controller for the case fans and I guess I should use that one instead of plugging them into the mobo as well, right?
I also wanted to ask if there's any fix to an issue like this? Anything I could do, any settings to change in the BIOS or is it just a faulty mobo/sensors and I will never get any automatic fan control out of it?
Thanks for reading. :)
