HI all

I have a PIII 500MHZ and i needed to flash my bios to use a 40 GB HDD i bought (my bios would only accept 32 GB). All went well but after upghrading my CPU temp is alway at 80C.
I have tried cleaning my PC (removing dust) with no luck... What else can i try ?
Thanks !

maybe you messed something up while you were installing the new hard drive? or maybe it runs hotter?

Actually I was already using the hard drive before with EZ-BIOS... The hard drive really runs hotter than the old one but since I was already using it, its not the problem...

Reapply the thermal paste between your CPU and its HSF.

You don't actually believe those wrong temps you get from the cheap thermisters they use on motherboards do you?

80c!!!! that would most likly melt the cpu socket....thats freekin hot man..touch the heatsink..does it burn you? if not then you not at 80C!!!!

right, 80c can melt metal, we're not talking about solder here....oh, and yes, the human finger is the best tool for determining temperature. Where do you get these thoughts???? Anyways, Bernard, even if you do or do not have that high temperature, if you're someone who doesn't take chances, just get a new HSF and fan, then maybe some additional case fans. So if you have the 80c, it'll drop with the new stuff, if you never did, doesn't matter, with all the cooling your PC will never overheat.

I got 81C once when my Volcano 7 wasn’t seated properly on the CPU core. Fortunately, it didn’t hurt the CPU. There was no smoke and nothing melted.

I just installed MBM 5 and it states my current CPU temp is 70C but in my bios it says 81C. Wich one is correct ? In MBM compensation for the sensor is set to zero.
Thanks

Which one is right? Probabley neither. Most AMD's will lock up around 70°C and stop functioning.

I wouldn’t trust either as accurate but both are too hot in my opinion. I’d have more faith in the BIOS temp.

Sterling_Aug : My processor is an Intel 500 MHZ ...

Can my problem be just the new BIOS reporting a wrong temp ? Cause it used to work fine before the upgrade... or can some change on the BIOS settings make my PC run hotter, since all my settings were erased during the flash ?

OH MY !!!

I left my PC playing a DVD for 15 mins and after that the temp was 90C !! I really cant believe this is possible.... Someone please help me...

just get a new heatsink and fan, like a thermalright ax-7 with a delta fan

Stop listening to some of these stupid posts - open your case up while the pc is running and make sure your fan is spinning on your CPU & if it is touch the heatsink to make sure its cool - also you will 'smell' the heat if the heatsink wasnt on properly, lay it on its side and put a hand pretty close to see if heat is being emitted, at 90oC you will feel it- if the cpu is cool then you may have flashed with a wrong version meaning it will not be able to convert the resistance from the NTC thermistor into a digital level causing the problems you describe - my monitor software says my 12 volt rail is at 99 Volts and if it was my board&cpu&hd would all be dead! it also claims my fan speed id 99999 Rpm LOL - Also u sure its not now reading in oF instead of oC?

Thanks mike.

Yes, I'm sure its 90C. I dont belive i flashed the wrong BIOS, since evrything is working fine (except for the system being too hot). What I dont know is if its just the BIOS reading the wrong temp or some change introduce in this BIOS version makes the system run hotter. I tried touching the heat sink and i couldnt hold it for too long... and the upper part of my CPU is hotter than it used to be (i can tell it from the outside). Can a change in the BIOS settings be causing this ? Cause all my BIOS settings after the upgrade were back to default (and I didnt write down the settings before upgrading)...

P.S. I'm using an AWARD BIOS.
Thanks

Geez, Mike is right, some of these replies are downright stupid! 80C can melt metal?? The melting point of rosin core 60% tin / 40% lead solder (the type most commonly used in electronics) is approx 185C (365F)!

The max safe temp for a P3 is 80-85C & the temps are reported by the thermal junction inside the CPU. If your temp is truly 90c (194F), I doubt you'd be able to touch the heatsink & hold it. Plus you're CPU would be causing you all types of problems (i.e. crashing, lockups, blue screens, auto reboots)...or worse, it could have fried!

yeah...90c is truly hard to believe and you are not experiencing any lockups. Just keep in mind that bios updates can solve one problem and cause another. If you are not locking up or computer not restarting then its probably not at 90c. like the other posts said open it up and touch the heatsink (make sure you are touching the case with the other hand before touching heatsink). Also keep in mind that intel chips slow down when they get very hot.

huh?- Thanks for helping me.

P4sucks- Yes, I can touch the heat sink and hold it for a short period of time, and Im not experiencing any sort of problems like blue sreens, self-restarts or lockups.
But I have a question : I heard that only Intel P4 chips slow down when too hot... does my P3 does it too ?

Thanks !

Yes, only the P4 slows down when it gets too hot. The P3 stops, and the Athlon/ Durons just melt.
