processor overheating

tacotanker27 · #1 (**permalink**) 02-13-2007, 11:42 PM

Is there a program that can tell if your computer is overheating? Whenever I play a game my computer gets louder and louder until it can't get any louder. At that point, the lag comes. Is this a sign of overheating?

Wanted to add that I found a program that tells your temperature, and harddrive, CPU, and memory use. Are these stats normal? :
-CPU:62 degrees C
-Harddrive: 36 degrees C
-AUX: 46 degrees C
-Memory usage:54%

I ran a game while I used this program and got:
-CPU 87' C
-Aux 65' C
-HDO 36' C

Is this too hot?

What kind of CPU do you have? 87C is very very high--is it a Pentium D or Prescott P4? No current CPU should be run at those high temps--but if you have an older cpu, it might be okay. Let us know your CPU and we can tell you if indeed that might be the case. But either way, 87C is very high.

dude it doesnt matter what kind of processor it is thats REALLY high!! First of all do you have a vid card? if not then the problem might be that your overclocking your cpu bigtime by using the onboard chipset for your graphics and your game itself. VERY BAD!! lol if that is the case i suggest getting a half decent vid card. if your in north america you can get a good one for around 100 bucks. now if you already have one then im gonna suggest trying to open your case while playing the game and seeing if its still loud like it was. if not then your problem is improper ventilation. you can solve this by getting a extra fan and putting it on the case so it blows the hot air out the back. if that wasnt the problem then look at the fan itself when your playing and see if its even moving. it might not be. if so get a new fan. anyways if any of theses awnsers didnt help let me know.

Yeah, I think that the thermal limit for the Pentium-D and prescott cores is something like 70C. I'm thinking that the sensor on the motherboard must be bad/reporting the wrong value--because I think at those temperatures, the dielectric of the resistors and transistors would break down, and the CPU would fry. But on the other hand, 36C for a hard drive isn't out of the ordinary. Odd. I would recommend trying another program--give speedfan a shot if you weren't using it already and see what it reads. you can download it here: http://www.almico.com/speedfan431.exe

Let us know what it reports.

I have a Radeon 9200/9250 chip set vid card, and a Intel(R) Pentium(R) 4 1.7 ghz. It has the standard fans and case, but I might get a faster fan if overheating is the problem.

It looks like the thermal limit for the P4 1.7GHz is 76C. Likely if the temp that the program reports is correct, the CPU would have failed by now--or (if the setting is enabled in the BIOS) the computer would have powered off by that temp. But it's possible that the CPU is still cranking away at that temp. Not sure if it's accurate--try another temp monitoring program like Speedfan that I mentioned.

Either way, it is a bit weird. Typically if you can hear the fans start cranking up when you do CPU-intensive tasks (like gaming), it is getting a bit hot. Simply getting a faster fan to blow on the heat sink might not be the most optimal way to go--if you plan on sticking with that computer for a while, you might as well just upgrade the heat sink as well.

Hmm, 87C would likely fry the Processor, but, maybe not. Plus, if it really is 87C, your motherboard should be detecting that and restarting (or shutting off) your computer to prevent damage. Unless, the Temp for shutoff, in the BIOS, was set to high? Shove a couple of fans in there, like one pointing in (at the front or side) and one pointing out (at the back). Maybe even add a couple of more. Or, it could be that the heatsink (the "gel" type stuff under the processor, between the Motherboard and the CPU) has worn down. Maybe you should try replacing that, but don't cheap out on the stuff, although it can get expensive...

I ran Call of duty and got a max temp of 78 C on Speedfan. What do you guys recommend for fans on this computer?

guyladouche · #9 (**permalink**) 02-15-2007, 03:18 AM

I would recommend this: Disassemble the heatsink/fan from the processor (clamps on the motherboard), remove the processor from the mobo and clean off all of the existing thermal compound from both surfaces--isopropyl alcohol is a good thing to use here. Let them thoroughly dry, and apply a good thermal compound--Arctic Silver 5 or something of the like. Reassemble the heatsink/fan and CPU (there are many guides and how-to's on this process on the net--just google it if you don't know what to do for your specific cpu/mobo). After everything, if the temps are "normal" (like below 65C) then it was probably the thermal compound breaking down, or was not applied properly in the first place. That's probably the cheapest solution. Otherwise, if you want to upgrade the heatsink/fan, we'd have to know the specific socket of the processor and your motherboard to be able to recommend a product.

Thermal compound, that was the word I was looking for in my post before.

Also, you might as well get a nice fan to get some air circulation. Try getting installing 2 fans (one in the front, pointing inward, and one in the back, pointing outward) that are at least 2000RPM. That'll make a nice air circulation in your case. Also try replacing your thermal compound.

Yeah, I figured you were talking about thermal compound--it was pretty easy to tell what you were talking about, so no big deal.

The fans are a good idea--and a cheap way to cool your system and see if proper airflow is the problem. Give that a try too.
