Default cpu temperature 80 C_>>is it normal?

hi. i have a problem with my cpu temperature.i have a intel pantium 4 at 3GHZ running at dual core...and my fan speed is about 2385 RPM ,but the cpu temperature is about 75-80 C.is that normal...?i mean even if when i'm in BIOS ,and my CPU status in idle...the tempertature is still 75 C 3500 RPM.
there is also o problem with my fan cooler speed cuz it fluctuates all the time.
noe i know that my fan speed is auto but...is it normal to change at any 2 seconds....and it does this strange sound.besides...when i'm playing a game that recuires my cpu activity ,and also gpu activity ...my screen turns suddenly blue ("beginning phisycal memory dump....window has encoured a problem and needs to close ...or smth") thank u all...and i appologise for my desastrous english

Physically, if is not dust in the fan or heatsink fins, it could be an ill-fitted heatsink which can be remedied by carefully re-seating it with thermal paste, having throughly cleaned the heatsink and CPU surface (checking the bracket is itself in position.)

What is your motherboard make and model?

It could be a BIOS setting like thermal throttling or target temperature.

Also, is the case well cooled?

If you are running a HT cpu, you will have divide the temperature by 2 (if HT is enabled). Try to disable HT in the bios and check the temp again.

In the bios, there should be a temperature indicator, please check this.

why would you divide the temperature by 2 considering the thermal sensor is under the cpu in the center of the socket.

also

try getting a better heat sink make sure it has a copper core and find something called arctic silver 5 its available at your local computer shop.

I got this reading in Windows with a program.
Don't remember which program. When I swithced to non-HT the temp went back to 40°c instead of 80°c. I could not make out of the original post that temperature was measured from within the BIOS or Windows/ Linux.

Sorry for try to help out.

No, I believe that temp is well above normal: 55-60° C, 65° C at most would be sustainable in a medium term period. I've a dual Xeon 3 Ghz set to turn itself off @ 70°C...

I also find strange that fan speed is lower at higher temps (2400 rpm @ 75-80° under charge, and 3500 rpm @ 75°, idle). To monitor your temp, and eventually control your fan, you might use some freeware utilities. Speedfan (http://www.almico.com/sfdownload.php) might be one of those.

Have fun (and chill!)

i had an intresting issue with a cpu reporting 80 c it seamed that the heatsink was of poor quality the thermal compound was very porly done causing it to over heat. luckly it was only for a short while on my semi bench / floor -_- i will be purchasing this pc as a trail factoring machine... older p4 manly i think is the core.

Your problem sounds familiar.

i've seen 70c+ P4s before, both had broken mounting brackets (its particularly hard to detect on socket 423). This prevented the heatsink from contacting the cpu correctly. Super-glue fixed the problem. Since you described an LGA 775 cpu, this may not pertain to you.

this is a socket 478 mounting i put a new heatsink it runs arround my other p4 at 122 to im guessing 130 degrees F so 49 - 53 degrees C
