Hey folks i just wanted to find out if my cpu is overheating and what the problem could be.. my cpu is currently at 85 deg(while running a spyware scan) which seems really high :rolleyes:! My fan is running at about 2800 rpm? is that too low?
What is considered a high cpu temp?
I dnt know much about these things, any help would be appreciated. ( btw i have a fujitsu siemans comp, p4- 2.6 ghz,512 mb ram)
 
Hi,Firstly,what are you using to measure the temps with ?
Download HWMonitor or Realtemp.
These are probably the most accurate measurements were likely to get..
OPerhaps also open the case and have a look if the cooler is not all bunged up with fluff and dust..Usually this is the case..
 
What cpu is it , if its a quaddie e.g. q6600 see my thread on "q6600 users needed"

Ouch! Do you need to cook eggs on your heat sink? That is very high, if the reading is too be believed. I have a FS laptop that did the same thing, but being a laptop you could feel how hot the keyboard was getting.
 
Open case, get rid of the dust, remove heat sink, clean it (use isopropyl or even anil varnish remover) and then reapply thermal compound. Temps seem way way high even for a p4

You should be looking at a MAXIMUM (which is still high) of around 60 degrees! :eek: Mid 40s is best.
 
Thanks for the replies.
Im using sensor's view pro to check my temps.
Anyways,it seems a bit better now after removing a lot of dust from the heatsink(vacuumed it out) , idles at around 40 but still reached 80 at very high cpu usages :(! (80-100 %)
And its not a Q6600 by the way.

It also makes like a hissing noise at high temps(which it did previously too) :confused:
I tried to remove the heatsink, unhooked the latches etc but it was loose and not coming out(i dint see any screws ?)..anyways i dnt have any thermal paste so i'll have to get some and try to remove the heatsink again later.

You'd only need to apply thermal paste if there isn't any on already. If it reaches 80C, the heatsink is most likely just loose. Take it off (there are no screws) only plastic latches which lock into the motherboard's plastic "frame" or whatever you want to call it. If there is thermal paste on the cpu and heatsink, then it's fine. Just reattach the heatsink, make sure all 4 latches are locked in place and feel if the heatsink is locked nice and firmly to the motherboard.
The hissing noise is probably just the fan spinning extra fast since the motherboard senses the CPU getting so hot and tries to cool it down by spinning the fan faster. Wouldn't help much if the heatsink isn't firmly attached :)

If you're afraid of breaking something, get an experienced forumite in your area to help you out for free, else take it to a PC shop you trust and won't rip you off :)
 
I am amazed that your PC doesn't automatically shut down at those temps. They obscene!
Those P4's are known for running hot but 80C is too much. It definitely sounds like your CPU is not making full contact with your heatsink. I assume you using the stock Intel fan that came with the CPU. It sounds like the type with the levers on each side. Once you've loosened those you have to unhook the clips that are hooked into the groove on the side of the aluminum heatsink. That will remove the fan assembly and allow you to lift the heatsink off the CPU.

Wash the heatsink under the tap to get rid of all the dirt and dust. Make sure it's dry before re-installing. Try blow as much dirt out of the fan assembly that you can.

I highly recommend you get decent grade thermal paste. When you apply it to the surface of the CPU don't put it on too thick. It is designed to fill the hairline spaces between the CPU and heatsink. The best conductor is still metal on metal so an excessive layer of thermal paste is wasting and probably counter productive to cooling.

Make sure the mounting is not loose when you finished, by holding the fan assembly and wriggling it. There should be no movement.

I hope these tips help. Let us know how your maintenance went and if it helped with the temps.

ummm heat sink 101, if you ever remove your heatsink you must always clean both the cpu and heatsink then reapply thermal compound. Once thermal bond is broken no point in just putting the heat sink back on as it is basically doing bugger all then.

Probably only if you use something like Arctic Ceramique which actually gets super hard. I've seen plenty of CPUs just being remounted without any probs. Mind telling me what a "thermal bond" is?
 
lol it is the bond between the heat sink and the cpu pretty obvious.

I have never heard anyone before say yes remove the heat sink and then replace it if there appears to be some compound left over.

Ceramique you will prob not be able to break anyway as that is a pretty permanent bond.

Most of my info comes from Toms/Anand so if you have better sources then please post away i love learning :D

Nothing beats personal experience :p
 
no bad memories here, i would rather believe the countless peeps i have seen post about this particular subject than 1 persons "personal experiences"

Maybe he got lucky but i will not risk thousands of rands worth of hardware on a crap shoot because in his personal opinion it is right to do so :D
