Speedfan CPU temperature monitor problems

'Bbutter Smith' I have a new computer so though it would be cool to see what the CPU temperature was. Anyways I download a program called speedfan which does such lofty thing apparently. It gave several temperatures, I am unsure for what but they were something like:- Ambient 24C CPU 27C CPU2 104C (with a little flame icon deside it!!). I found that rather worrying!! 104 seems very hot. I am not sure what this means I don't thinkI have a CPU2 but I also read that CPU2 was the main CPU!!!

There are several types of temperature sensors. The two most common in PCs are thermistors and diodes. Thermistors don't use the same conversion factor as diodes. Usually when you have a completely unreasonable temperature, the conversion factor is set incorrectly in the display program. The 105 C reading is likely caused by a setting for a thermistor, when the sensor is actually a diode.

Just looking at your three sensor readings, if 24 C is the room temperature:

the 27 C is likely the motherboard temperature, not the CPU temperature

the 104 C is likely the CPU, but with the wrong conversion factor - it is reading about 50 C too high.

A CPU temperature when the CPU is not under a heavy processing load is too high, especially if you are interested in overclocking.

Getting the CPU temperature from the BIOS is not a very good indication of running temperature, because you have just booted up the computer, and very little processing is going on.

You should check your cooling: ventilation of the system case dust in the heatsink fins thermal compound and mating of the CPU to the heatsink.

Anywaywhen I exited the program I noticed it speeded up the fan mbuttively (my computer was nice and quiet before hand). Bare audible. Anyway I rebooted and all was back to normal nice and quiet no roaring fan. I am pretty sure my CPU was not at 104C, I tried another similar program, Hmonitor which reported similar results, ie CPU2 at 104. I just tried hmonitor again and it says 109C!! Surely this is a wrong reading. Not willing to use Speedfan again cos I eblieve it is 'unsafe'.
