Help! CPU Running waaay too hot (80 degrees celsius)

Hey everyone,

I found this website after trying desperately to get help for my problem. My Computer gets upto 80* celsius (if not more) when I run games!! This is my system specs:

Asus P4P800-S
Pentium 4 3.2GHz (800MHz FSB, 512kb cache)
My fan is a: VANTEC VP4-C7040 TMD (URL: http://www.newegg.com/Product/Product.asp?Item=35-110-008&depa=0
1GB DDR Ram

The problem is: A few months ago, my computer started restarting unexpectedly while running PC games. It was an every once-in-a-while thing but then it became more frequent and now I can?t play games for more than 15 minutes before it restarts. I have never overclocked my computer in any way nor tampered around with the settings. ALSO: Sometimes, when my computer would unexpectedly restart, it would take about 15-20 seconds for windows to start loading up again and sometimes, it would display weird messages during booting that said stuff like

"Overclocking failed!..."

and some other very rare times, would also say something about the voltage being too high, very strange because I never have messed with the settings. I called Intel, they had me re-apply thermal grease to the CPU because they claimed the grease was probably dry after 2 years of me owning the computer. But since im not using their factory fan, thats all they were willing to help me on. I reapplied some thermal grease and it helped out a bit, cooled my comp by about 8*c max, but it still gets up to almost 80 Celsius. I use SpeedFan v4.28 to detect temperatures and it tells me the following information for my CPU voltage:

Fan: 5192 RPM
Vcore: 1.62v
+12V: 12.40V
3.3V: 3.34V
Vcc: 5.04V
Vin2: 0.00
5Vsb; 5.01V
Vbat: 0.00V


HELP! I don't know if on one of those unexpected restarts, maybe the computer's voltage settings got changed somehow and now it runs with more voltages. Is that possible? Any clues as to how I may fix this? I have cleaned out the dust VERY well from my tower and I reapplied thermal grease on the CPU. Is it a fan problem? Maybe I can get a Zalman fan...

Thank you VERY much for your input, I am very worried about my system.. it's just not the same system I once built anymore.

Just a quick thought, and I don't know if it relates, but have you checked your CMOS to see if the board is still recognizing the chip correctly? If the FSB, multiplier or another setting got changed, it may be attempting to overclocked, even though you don't know about it.

If that happened, try clearing your CMOS with the jumper and resetting your preferences.

Good luck. 🙂
 
Thank you very much for your reply =)

I do not know how to go about checking the CMOS or what it is. Is it possible that it could have gotten changed simply by my computer restarting unexpectedly in the past?
 
Yes, it's possible. To get to the CMOS, when the machine first starts, you should see a message, usually at the bottom of the wake up screen, that says something like Hit Del to enter Setup. Some brands use F1 or another key, but Asus usually uses Del.

Tap whichever key is called for several times as soon as you see anything on the screen. You'll find several pages showing how your system is set. For the CPU, make sure the FSB and multiplier are correct, or that it's set for the default or Auto setting.

If anything looks out of line, there should be options to reset to the default or fail safe settings. If that gets you back to normal operation, you can then reset the rest of it to your preferences.

If all else fails, try clearing the CMOS with the jumper. If you don't have the manual, you may be able to download it from Asus as a PDF, or you can just look for the jumper closest to the battery. Don't forget to replace the jumper back to the normal operating position before you restart the machine.
 
I tried doing just that, I looked at the manual for my motherboard and did the proper procedures for refreshing/resetting the CMOS but still, my processor runs just as hot :-(

I don't know, I imagine that my heatsink is good enough, but then again I don't know much about good heatsinks. I was looking into buying a Zalman CNPS7700 CU, it's the all-copper one and also adding a few fan cards to my tower. But I am not sure if that will resolve the problem. Any ideas?

Likely reasons the CPU would get that hot:

1) the heatsink's fan is stalling. Do a reality check to make sure it doesn't take naps on the job.

2) the thermal-interface material between the CPU's heatspreader and the base of the heatsink is absent, or dried out, or poor quality.

3) the heatsink is no longer making effective contact with the CPU's heatspreader because of a broken heatsink clip or a broken retainer frame, or the heatsink simply came unclipped from the frame. This can appear to be OK until you look very closely. Check all four corners.

Adding to the list ...

4) Heatsink fins are dirty and no longer allow for enough airflow to cool the CPU down.

5) Heatsink fan may be unplugged from the motherboard.

The first thing I would do would be to reseat the heatsink using new, high quality thermal interface material or Arctic Silver 5. I would also clean the heatsink fins of any dirt/lint/hair that may be impeding airflow. Make sure your fan is plugged into the motherboard and that nothing is stopping it from spinning.

Addressing those 5 things on the list above should bring your temps down. Although, maybe not enough. I'd consider some extra case fans to improve airflow through the case if you're still experiencing heat related issues.

 
Thank you all for your help! I will try out the suggestions and will inform you of how it goes. Thanks again!

I just went ahead and bought a Zalman CNPS7700-Cu (All copper) and my CPU now runs at 41 celsiusidle! Amazing, before it was at 60 celsius, eek. I used Arctic Silver 5 and I made sure I spread it all over the top of the processor, there wasn't a space that didn't have goo on it. I think my old fan was just not cutting it anymore and I am really happy with my purchase of the Zalman! =)

Thank you all for your input!
