127C in SpeedFan, normal?

I just installed SpeeFan. One of the 3 Temp is 127C!!! How can I tell which temp it is measuring?

 

Click the CONFIGURE button and it should pop up a list with more detailed info (look in the "Chip" column).

I'd bet dollars to donuts it's your display card (NVIDIA, I assume).

Mine runs 100C+ just at an idle Windows desktop and I've given up trying to figure out why.

 

The BIOS shows 43C for CPU and 37C for System.

Everest Free shows 88C for GPU and temps for all HDs. It doesn't show any other temps.

SpeedFan shows 88C for GPU, 50C for Temp1 (CPU?), 37C for Temp2 (System?), and 127C for Temp3.

 

I would ignore the 127°C. Your motherboard utilities disk should have a monitoring program (or check for a more recent version on your motherboard or PC maker's website). If none, I recommend CoreTemp for newer Intel and AMD64 CPUs. As noted, SpeedFan is a popular alternative, or you can try Motherboard Monitor, which is what I use. Unfortunately, I have found that these programs often have problems properly identifying and labeling the sensor they are reading. The temperatures shown are as accurate as the inexpensive, low-tech sensors will allow, but it may say System Fan instead of CPU Fan. So I use Everest to verify the temperatures (as it seems better at putting sensor to label correctly). If one program is not accurate, one of the other programs may be. SF does not accurately display my CPU temp so I use MBM. You might try all three (four counting one from the motherboard maker) and see which meets your needs best, then just run with that one. I like to keep my CPU temperature displayed in my system tray, MBM and SF will do that, I don't think CT will.

Fortunately, SF and MBM allow you to edit the labels. So you can use Everest, then edit the appropriate label. Everest does not minimize to the system tray, otherwise, I would use Everest instead of the others.

While checking the temps in the BIOS is a possible way to check the sensors, running the BIOS Setup Menu is probably the lease demanding task you can ask of a computer - so lower CPU temps in the BIOS are expected, and may not reveal a heat "under load" condition. This can make if difficult to verify labels with the windows based programs as typically everything gets warmer with Windows running, even when the computer is more or less "idle".
