BIOS is reporting very high temps for my CPU

Ok so this morning i turned on my computer after it was off all night, and within a few seconds of it powering up, it started beeping and said on the screen "CPU temp too high" or something like that. So i went into the BIOS screen and checked the temp, it said 79°C, how could this be, the computer was only on for less than a minute.

Also ASUS PC probe II reports temps of the same magnitude.

BUT, when i use coreTemp to meausre the temps, its gives me a much more reasonable temperature of between 30 - 35°C.

What might be a factor is, a few weeks ago, i was in a rush to get out of the house, so in my haste, as my computer was shutting down, i turned it off at the wall, As soon as i did this i realised my error. And since then the BIOS has been giving these high temps, which seem to get higher every week, but coreTemp is giving the more realistic (and constant) values.

my question is, why is this happening, and what can i do to stop it, because i had to torn off the setting to give me a warning because, well i dont want a false warning everytime i start my computer

The heating in the room my computer is in is broken and constanly on, so its quite warm in here, so thats why coreTemp is giving 30+°C value, but before the healing was broke, CPU temp would give values like 24-27°C.

Specs:
CPU : see picture not overlocked
MoBo: ASUS M4N82 deluxe
Ram: 4gb
cooler on CPU : Zalman CNPS10X Extreme
 
Chances are its full of dust , one of your fans has failed or the heatsink is no longer secured properly on the chip.

Clean it , check the fans and if they do not fix it reseat the CPU heatsink and fan.
 
but, the fan, CPU,and motherboard are only a month old, i ordered tham all of overclockers last month. and i have already re-set the heatsink a few times.
 
Hey P-o-r-k-y,

that's a good one, having read your description of events above I think maybe you did something to the BIOS when you powered it off in haste? . . . dunno, the fact Core temp is still reading normally means your chip isn't frying (I assume the Core temp readings actually move?), what you could do for a quick bit of piece of mind is open the side panel of your computer and carefully touch the heatsink and CPU socket area to see if its sizzling! take care just in case it is . . .

If you touch it and its not particularly hot then thats kinda points to the BIOS sensors going awol! :p

Um, you could try reloading the BIOS defaults to see if that jiggles it back good, if that doesn't work you could then try clearing the CMOS with the hardware jumper, if that didn't work and acting on the premise that it is indeed a BIOS code related issue the last thing you could try is Re-Flashing the BIOS . . .

Nothing else leaps out at me, let us know how you get on! :cool:

Thanks for the reply

I took off the side panel and i put my finger down at the base of the headsink, where it meets the CPU, and its just feels room temperature, its definitley not what the BIOS reports it as, which is a relief.


So how do i reload the BIOS?
I updated it earlier today using the ASUSUpdate utility that came with the motherboard, but its still the same reading

well if your heatsink isnt hot that could indicate its not making good contact, not the other way as you seem to think if the heatsink is cool so is your cpu, dont think it works that way;)

hyperst is right but I thought I made that clear in my post above, sorry if any confusion caused! :)

What I mean by "CPU socket area" is the area directly around the CPU socket, like the heatsinks, VRM's, PCB, Capacitors etc . . . . if the heatsink isn't fitted correctly all the surrounding area will be extremely hot!!!! :cool:
 
Ignore the bios temps, core temp is more reliable since it reads directly from the CPU, but just to be safe download Real Temp for a double check. My Striker Extreme shows 128 in the bios but the CPU hasn't fried yet.
