Product: HP Pavilion Elite m9517c Desktop PC
Operating System: Microsoft Windows 7 (64-bit)

My desktop motherboard is reporting that the temperature (TMPIN0) is 50 degrees C all the time, even when its at room temperature. This causes my power supply fan to annoyingly run full blast all the time. If I could find the manual for my motherboard, then maybe I could  find a loose temperature sensor or other problem. Can someone help me find the documentation for this motherboard? Pavillion Elite m9517c Ser No MXX91509DL Prod FQ574AA

 

Thanks, Mike

Unfortunately, there is no motherboard documentation available for your Pavilion Elite M9517c.

HP used to provide that, but now it is quite rare to see it.

The only documentation available is at the hyperlink below this.

There won't be a "loose" temperature sensor for you to find.
The temp sensors  are embedded in the processor chip and in the chipset.

 

 

50 deg C is actually running nice and cool.  

 

Check in the BIOS to see if the "always on" option is set and put it on auto instead.

Yes Erico you are right, 50C is not that hot. Maybe Im barking up the wrong tree, the fan mounted on the CPU is not the one blasting, its the one in the Pwr Sply. Now that you got me re-thinking this, I bet the fan in the PS is internally controlled probably by an internal temp sensor and the fan speed has nothing to do with the motherboard temperatures. You agree?

 

I couldnt find a FAN setting in my BIOS btw

 

Thanks again

Mike

The fan speed is controlled by a firmware algorithm in the BIOS ROM coding that uses a temperature sensor derived  trigger to ramp up fan speed when the temperature exceeds the processor maximum temperature.

 

There are at least two sensors between the processor and the motherboard.

 

You can probably find a setting in the OS to select other than a performance setting for the processor.

It will be in the Windows OS power settings.
