Is this a laptop or a desktop system? If it's a desktop, open the case and verify all fans are turning and there is no accumulated dust on the fans and CPU heatsink. Also verify the heatsink is properly fastened to the CPU.
As for the numbers you posted, they don't make sense.
2.52C is almost zero degrees (32F). Did you mean to enter 25.2C?
Also, you said Temp: 1: 1C which again is almost 0 degrees (32F)
Maybe posting a picture would be clearer. Let it run for 20 minutes or so then capture the screen and post it here following the direction at the link I gave you.
Edit: I just checked my HP Pavilion 750C and Temp1 and Temp2 both register as -120C so SpeedFan doesn't work with all system, too bad.
