Bios reporting insanely high cpu temp

Hello!
First I'll start by mentioning temperature monitoring is fairly new territory for me so please correct me if I seem to misunderstand anything.

Anyway, just recently I noticed my fans making more noise than usual so downloaded speedfan to check it out and astonishingly it revealed it was reaching 90 degrees celcius under load. Naturally I invested in a new cpu fan. (arctic cooler 13)
Simple install, cleaned off old thermal paste on cpu and initially just went with what was pre applied to new cooler.
Everything boots up fine, I check the bios and now see 127 degrees celcius... This is after a cold start, computer had been off all day before I made the switch so in the couple of seconds booting in to bios the cpu thinks its heated up to 127 degrees. I would like to think that I can safely assume this should be impossible, but you never know.

So since then I've tried going back to stock cooler and still it's 127 degrees with speedfan giving the same reading.
To rule out that I had been sloppy, I have since cleaned up the cpu and heatsink with some isopropyl and applied some new thermal paste (arctic mx-4). This made no difference to the reading I got. I have since repeated the cleaning and re-applying process with varying amounts of paste in the hope that my definition of "thin layer" would match that which works best. Still no change.

Anyway I have since downloaded CPUID HWMonitor and CoreTemp. Rather pleasingly they both report 33 degrees as I type this.
So does anyone have any idea what's going on here? I understand that bios gets its reading from the socket, so I was wondering if there's anyway to test for faults or if I can simply reset the reading in anyway. On that note, returning the default or optimized settings through bios has no effect.

I'd be grateful to anyone that has any ideas as I don't know what to do.

I'm trusting HWInfo as I'm feeling nice and breezy cool air flowing around my system. I would just like to know if there's a way to bring that 127 C down as I believe it's causing my cpu to throttle the clock multiplier to 7 instead of 18. I'm losing a huge amount of processor due to this.
 


If the CPU is heating up too high it means that the CPU/heatsink installation is not right and in the case of a radiator the pump is going bad.

It is always an inadequate heat transfer problem.
