SpeedFan giving incorrect CPU temp?

[Nagarya]

I just built my first computer yesterday, and went to install SpeedFan to monitor the temperature of my i5-4670k processor. I start it up and it shows my processor at 128 degrees C. I quickly downloaded CPUID HWMonitor and then Core Temp, and those say I'm perfectly fine at ~32 degrees C. When I go into my bios, it shows my CPU temperature at 44 degrees C.

Is it safe to that assume SpeedFan is giving me an incorrect reading? I just want to be sure that I didn't incorrectly install my Cooler Master Hyper 212 EVO or something.

EDIT: The fan on my cooler was spinning with no problem. Also, I powered down and unplugged, opened up the case and put my hand an inch away from my CPU cooler's radiator and felt a slight warmth, but nothing hot by any means. I'm really hoping this is all pointing to a faulty reading by SpeedFan >_<

If the other two programs consistently gave you "more reasonable" measurements, then it's safe to assume that Speedfan, for whatever reason, was at fault.

CPUs will usually shut down long before they reach that temperature; it will start to do serious damage.
