Motherboard Reading Fahrenheit rather than Celsius?

Recently I updated my motherboard's (which is an Intel DG31PR) BIOS and other drivers mainly to get it functioning with newer CPUs, which at the moment is using an Intel Core 2 Duo E8500. I had swapped processors before and still the same thing happens.
The main issue is that the fan is going on incredibly high speeds to the point where it's annoying. I tried plugging the fan into different slots, and still it continues to go to very high rpm speeds, about 3000rpm.
It reads about 98 degrees, which could not be Celsius as the CPU's max temperature is about 80 Celsius or so. I deducted that it's reading the wrong thing, and this is on the actual BIOS screen, not any free-ware. Freeware like SpeedFan does read the Fahrenheit reading as well.
I couldn't seem to find an option on the BIOS screen to change the reading from Fahrenheit to Celsius, so I assume this is some kind of drive bug. I really would like to fix this soon too, thanks.
Also one more thing to mention is that the fan runs normally only before the BIOS screen comes up.
 
Motherboards always measure temps in C, so I would go with that the reading is real. The fan is trying to cool it- unsuccessfully.

The first thing is to open the case, and clean out any and all dust. Pay special attention to the grates and fans.

Also, did you apply thermal paste to the top of the CPU? A thin layer is what is needed, as more than that can work to insulate.

The E8500, which I used in a work computer at one point, did not run superhot, but was not exactly ice either.

Of course. When it first happened I took it out and re-applied it and tightly fit the cpu fan over it. Still same thing even when I swapped CPU's from an E8400 to an E8500.
An E8500's max temp is around mid-70's according to others. If those temps were real I'm sure the cpu would have died by then, even when running the OS I assigned to the hard drive its connected to.

Late reply, havn't been on here as much, but I believe it's a stock cooler from when a Pentium 4 at 3.0 GHZ was on it. With the pentium 4 it cooled it enough, and this had netbursting archetecture. I'd assume an Intel Core 2 Duo wouldn't be as hot to get to 96c with it. Moreso, I don't understand how it's a 96C when it should have melted through the motherboard at the temperature.

I'll try that route. But, what ones do you reccomend? I'm using an HP Pavillion case so it's smallish.

Yeah that one is too big, I tried using that in this case before when it was my main computer, with different hardware and stuff.

The width of the tower is about 6.5 inches roughly.
