I have not overclocked my system. Just recently my PC CPU is extremely hot, it's 91C, I have amd3000, it has never been this hot before, just over the last week. It's been reseting it self, all my fans appear to be working, any suggestions or help?
thanks
 
When you say appear to be working do you mean you opened up your case and the cpu fan is actually spinning?


And btw over 75c is damaging your cpu so dont run that system.


Here's what a 1.2ghz duron looks like after dust clogs the fan causing it to stop spinning and melting the fan... Blah blah blah :D

It still works though :p
 
Definately go into the bios and set it to default settings. Hopefully the temp sensor is wrong? Check your airflow. I've seen some cases that have two fans competeing with each other.
 
Sounds like one of three things has happened:

1) you cpu fan has died, open the case and see if it's spinning.

2) your heatsink has clogged with dust

or

3) your thermal material has dried out a turned into an insulator rather than a conductor of heat. If your CPU fan is spinning then this is probably it, especially if it's more than a year or two old. Take off your heatsink. Clean the top of your CPU and the bottom of the heatsink to make sure all the material is gone. Then reapply a new layer of thermal material and put your heatsink back on. Fire it up and see if your temps go back down.
 
Well I opened up my case, all my fans seem to be running. I even downloaded SpeedFan, it now says my temp is 62C, I haven't compared that to my bios, but I'm going to do that right now? Which temp would be more actuarate, SpeedFan or the bios reading? Ok I will take off my fan and see if my thermal is ok, just worried cause my fan was a bitch to get on lol.

Go into my bios and set to default settings, what do you mean, I think they are at default settings already but i will check

Thanks guys

Remember, if you take your heatsink off you have to repkace the thermal material.

I'd like to add.. That means you can't try and reuse the old stuff especially if your cpu is running that hot it probably needs new thermal grease\pad anyway because of the extreme heat.
 
I actually took off my heat sink, and there is no thermal paste on it. I cleaned out the fan, ass well as the heatsink and i know run at 64C is that still high? I'm getting paste tomorow, how do I actually apply it? what do i put it on, the silver chip in the middle of the cpu?

thanks
 
Make sure your HS/F is attached properly! My C2D hit 90c+ and kept shutting down. I put on AC5 and attached the HSF properly, now its down to upper 40s.

Holy crap man wherever you got your computer or whoever put it together for you is an idiot. Do not go back to them or even let them touch your computer again. Yes an idle of 64c is really high.
 
I checked my fans again, put on thermal paste, my cpu fand and heat sink are on properly, clean out all the dust and i still run at 61C... any suggestions?
 
Throw up what processor/heatsink/mobo you are using atleast so someone can tailor the information for you situation. Take a picture if you can also. Those temps are pretty high.

What paste did you end up with?

Are you cleaning the heatsink base and processor before applying the thermal paste?
 
I cleaned everything, a generic paste brand, here are my specs:

Remount it again and go slow this time. Make sure you press evenly on the top of the HS when pushing in the clips.

Did you by any chance use all the paste in the small packet they give with heatsinks?

The way I apply the paste is to apply a bit (use the artic silver website for instructions) and then spread it with my finger wrapped in saran wrap. Then I even it out using a card or blade.

What are you using to clean the surfaces? Maybe that is your problem.
 
Well actually I didn't put much paste on, I was told not to over do it or it can conduct heat itself, how much past should I put on and how thick? It 10g tube of thermal paste

Actually you'll want the paste to conduct heat, so too much and it'll become an insulator and trap the heat in the processor (bad). The amount you use depends oon whether it's an open core processor or an lidded processor.

For open die processors I just put a small dot about the size of half a grain of rice in the center of the die and let the heatsink spread it out.

For lidded processors I use a dot the size of a full grain of rice and spreed it out with the edge of a credit card or razor until it smoothly cover the whole lid.

Other people will tell you differently, but that's what has worked best for me.
 
It's an open core proccesor, I did what you said, and I'm still running at 55C, it seems weather my pc is working or not, it stays around 55C... I remeber when I first had my pc build it was around 47C, now it's a even higher, not sure I'm running out of options

Is the heatsink full of dust and dirt? That'll impact your temps. Also how is the airflow in the case, is you PSU the only source of ventilation?

If you're heatsink is celan and there's pelnty of ventilation, I'd say that the thermal sensor under the cpu has gone bad.
 
We started carrying AS5 at my little Radioshack store, so others may be carrying it now.. If there are no other PC type stores around hit up the shack.. its like 10$ for the tube, but you DEFINANTLY need to get some paste on there..
 
Now that I think about it, my mom's Compaq Presario iwth an XP 2400+ idles around 50c and load temps are close to 60c. I've done everything I can to get it down, but it just won't get any cooler. May just be that those AXP's are hot running processors? I know the thunderbirds were scorchers, but I though they fixed that by the time Thoroughbreds came out.
