Page 1 of amd cpu overheating

hi all have an amd athlon 2100+ xp cpu which is running at 65c in idle windows keeps freezing up and the pc keeps switching off! i have replaced the heatsink and fan with a new more powerful one but this makes no difference! does this mean the cpu is knackered?
help please
thanx dug

Should go up to that or more under load, but a tad high for idle!

Did you use a good quality thermal paste and apply it properly? If you got a heatsink with a pad on the bottom, did you install it the right way round? The cpu die sits slighty to one side and so does the pad on the heatsink - if you put the heatsink on the wrong way round (it still fits fine, so it`s an easy mistake) then only half the die is actually covered with the pad causing poor heat tranfer.

Apart from that the only thing I can suggest is running the machine with it`s side off, or adding some cooling fans internally!

hi i have checked all that and it is fine also have had side off and had a fan blowing in and the temp only drops to 62c
thanx dug

ive got an athlon xp 2600 and my cpu temp is between 55 and 60. ive been wondering about this for a while. i was advised to check obvious things like the inside isnt dusty and that the cpu fan is working. mine clocks in at around 4000rpm which i gather is ok. im considering getting some system fans i think they are called to go inside. i asked a friend recently with a similar setup to mine and he has five fans inside, including graphics. i only have two. they are cheap enough though.

i recently had to install a new motherboard and applied some of this thermal paste but it seemed to be ok, covered everything that needed covering, can that increase the temperature towards 60 degrees if not done right? the figures ive read suggest the cpu temperature should be more around 40 degrees.

No - 60/65 is fine for a cpu under load mate. The more powerful the more heat they generate. I personally wouldn`t worry unless it starts to shut down like Dugs. AMD cpu`s run especially hot.

doogey :)

Try a case exhaust fan, about £6-8 and they can make a marked difference to the temperature of the system as a whole.

Not always the case. The old Palomino cores (Athlon XP 1800+ etc) run much hotter than the newer T`bred or Barton cores. I think the max rated temp for an Athlon 1800+ is 90c (same for 2100+), while a 3000+ is 85c cause thy run cooler.

My old 1800+ used to run at 70c-80c+ with the stock AMD fan. My 2800+ and 3000+ run at around 50c-60c with better cooling.

Yeah - I was just trying to dispell the myth that anything over 50c is bad! As your figures suggest, they should run fine up to some ridiculous levels.

Where do you find the cpu temperature ?
never checked it before

A lot of newer motherboards have the ability to check it for you. My ASUS boards use a bit of software called Probe that tells me the voltage, fan RPMs and CPU temp among other things. You`ll also be able to check in the BIOS on some boards, but that won`t really give you an accurate reading of the temp under load.
