• CPU temp sensor broken. What to do?
    10 replies, posted
So I recently found out that the temperature sensor for my CPU cores are broken, all showing 0 degrees celsius. I know that the CPU fan is controlled by the CPU temperature, meaning if the temp is at 0, the fan will never go above low speed, correct? To counter this, I simply disabled Smart Fan in my BIOS but now it runs on 100% all the times, which causes a pretty annoying noise. Is my theory correct? Is there anything else I can do, like making the fan run off CPU usage % or something?
Where are you reading the CPU temp from?
[QUOTE=GiGaBiTe;44931048]Where are you reading the CPU temp from?[/QUOTE] Tried both HWMonitor and SpeedFan, both show 0 degrees Celsius.
You could keep the fan running at a speed which doesn't cause an annoying noise but still at a high enough speed that it shouldn't overheat
[QUOTE=Donkie;44932061]Tried both HWMonitor and SpeedFan, both show 0 degrees Celsius.[/QUOTE] Generic software sensors are often wrong. Use the BIOS to get the temperature readings, or the sensor suite that comes with your motherboard since it's configured to read the correct sensors.
I have a Gigabyte GA-970A-UD3. Im not sure what I should be looking for? Drivers? What's EasyTune?
EasyTune is the OC software, but it should show the proper temp readings as well.

They're notorious for their CPU sensors working incorrectly on most software like HWMonitor and CoreTemp. According to HWMonitor, my A8-4500M is allegedly idling at about 97C right now, which I know for a fact isn't true because my laptop does not feel warm at all, my fan isn't spinning noticeably fast, and my computer doesn't shut down if the value goes above the Tjmax of 115C, which HWMonitor says it does when I'm playing games. I know the actual temperature is somewhere around 47C because the integrated graphics chip inside the APU is, for whatever reason, far more accurate.

turn off the core unlocking in the bios, that disables temp sensors
IIRC amd sensors are inaccurate at low temps but that's probably not the case
It appears that the EasyTune software gives me correct readings. I find it abit weird because HWMonitor and such worked fine before. I've turned SmartFan back on and it now adjusts to the temp. Thanks everybody!
