Hi Guys. Im having a problem with my computers CPU overheating. The computer keeps turning off because of it overheating. So i tried cleaning out the inside of the case, and still no help. So i went out and purchsed a new Heatsink and fan thinking that maybe my old fan went bad. The new Heatsink and Fan is much bigger so i thought it should work pretty good (atleast better than the stock). But the temperatures are still way to High. It idles at about 60 Degrees Celcius.
Does anyone know why my CPU is overheating. Also, my powersupply went bad. The computer still turned on but the powersupply was giving out the wrong voltages. I know this because i tested it with a power supply tester. Since then i changed the power supply but do you think it is possible that the power supply damaged my CPU and that is why it is overheating? Do you think a new CPU will solve my problem? Thanks for the help in advance guys.

Make sure you didn't install the heatsink backwards, it's a common mistake. Did you use thermal paste or was there a thermal pad pre-installed on the heatsink? If you used paste, you should be careful not to use too much. A dab the size of a grain of rice should have been put on the CPU core, then spread thinly & evenly.
You say the voltages were wrong on your PSU, then don't list them. The ATX spec allows for a 5% +/- tolerance, so for instance, the +12v could range anywhere from 11.4v to 12.6v & still be considered "normal". However, eMachines is notorious for using crappy PSUs...usually Bestec. Your replacement PSU should have cost at least $40-50 otherwise you probably replaced one piece of garbage with another.

I have installed the Heatsink and fan the correct way. I doubled checked. Also i used Antec Silver 5 Thermal greese. I applied the correct amount as you stated.
And also, on my old power supply, the -5V was reading -0.0V in the bios. And my tester also agreed that the -5V was not working. I replaced it with a power supply from Antec, $50. Do you think i fried my CPU?

"on my old power supply, the -5V was reading -0.0V in the bios"
Can you tell me what the -5v rail is used for? I didn't think so....
"I have installed the Heatsink and fan the correct way"
OK, just to be sure, you realize that there's a "notch" in the heatsink that must be placed over the raised portion of the CPU socket?

"Do you think i fried my CPU?"
No. I think you have the heatsink installed incorrectly. Either that or your BIOS is reporting the CPU temp incorrectly.

Did you thoroughly clean the CPU before installing the new HS/fan? Did you buy a HS/fan that is rated for the processor you have? Are you running the processor at stock settings? What is the case tempurature?

Too Jam, Yes i have the notch on the Heatsink in the right direction. And for the third time the heatsink is placed correctly. This is not my first time building a computer. And no i dont know what the -5v rail is used for, i never said i did, so dont be such a smart ass about it.
Too OtheHill, yes i did everything you said. Any other ideas. Thanks

"What is the case (system) tempurature"?
We here at Computing.net have NO clue what your abilities are. Don't take thing so personal.

Case temp is 25 Degrees Celcius. Thanks for the help, didnt mean to be rude, i was irritated by something else this morning. Didnt mean to take it out on anyone else. My appologies.

The -5v rail is rarely used. If (as is mostly) it is not available it often gets misreported.
A case temperature of 25C sounds quite reasonable.

If your case temp is 25c and the CPU 60c either the sensor is wrong or the cooler is not big enough. I asked before about stock settings. Emachines probably don't have many, if any, BIOS options but are you sure the settings for processor are correct? 25c = 77F. That is almost too good to be right. My rig is running at 36c & 41C right now. At any rate 35c difference is excessive.

AMD CPU's tend to run a bit hotter than intel's.
Nevermind about reading the temperatures: touch the heatsink. If your fingers feel like they're burning after 2 seconds, it's too hot. If however after 10 seconds you feel burning then they're not too hot ! Go to your BIOS and change your shutdown temperature to about 85 or 90
warning temperature should be 80
Try to get some ventilation into your case. Usually cases have an extractor fan at the back of them and they draw air in from underneath/front. Try taking one of the 5 1/2" drive bays out and letting air come from front. Make sure you are using heatsink silicon paste, but not too much of it, only a small spot between CPU and mainboard. Try adding a fan to your case that blows air from the side to the heatsink. Also try touching the heatsink of the north bridge to test the heat of that. It could be due to that. If capacitors on your mainboard are beggining to budge, you have heatsink problem.if all else fails, try down clocking your computer to see if it heats up.
SpeedFan helps find information about your Fan and temperatures, and even lets you increase/decrease fan speed on some mainboards.386 WITH Math co-processor eat your heart out! 25 Mega Hertz
