So I am running a MSI 990FXA-GD80V2 motherboard with an AMD FX 6300 CPU. I just finished the build and have yet to load any software what-so-ever. I am having a severe problem with my BIOS CPU Temperature monitor though. According to the read-out, the CPU temperature goes from 60-70 degrees Celsius to 92-93 degrees Celsius within a 45-60 seconds. For one, I don't think the laws of physics allow a piece of metal to heat up that fast without exploding or soldering to the motherboard (I have checked the CPU is fine) but the BIOS says otherwise. I can't run the computer long enough to flash the BIOS (I am running a back-up of the original BIOS off a flash drive) before it "overheats". What the heck is going on here?

Just for note, I have the side of the case open with an oscillating fan blowing cool air into the system, the front case CPU Temperature readout never goes above 30 degrees Celsius (it starts at 25), I have not messed with any kind of overclocking or anything to possibly get it up to that temperature, and the motherboard termperature is around 25-30 degree Celsius. I used the stock fan and thermal paste.

In summary, 1) Are temperatures like that even possible (just out of curiosity), and 2) How do I fix a faulty BIOS Temperature read-out?

Think I'd first look at checking voltages in the BIOS if possible, but regarless, pull the cooler and re-install, may have too much thermal compound or way to little

yes they are possible. check the cooler fan speed, and the voltages.

The thermal compound came pre-applied to the heatsink when I got it. When I do check the voltages, what should they be at for normal operation?

Less than 1.3 anyway

Okay so now I have run into a new problem. It is giving me a 19 POST LED error code. I think that is a lack of BIOS to boot up. I tried to reset the CMOS but nothing happened.

I contacted MSI and the POST 19 error means there is an early southbridge initialization which most likely means a bad board. I have to RMA it, just putting this here for anyone else who has the same problem so they can read it.

Thanks for the update, let us know when you get a replacement
