Maximum PC

my PC has been overheating and doing an immediate shutdown. I downloaded cpuid monitor and speedfan to check my temps. Here's what cpuid found. speedfan is a couple deg. different
I'm running xp pro and have a coolermaster cosmos case. With the case closed the temps rise 15 to 25 deg. right now I keep the side panel off and have a 12 inch fan blowing into it. I also have central air AC in the house.

How do I go about diag. and fixing this?

If those CPU temps are taken at idle with the extra fan in the side then I'd say you definitely have a problem. You haven't said whether or not you tried to reseat (with new thermal paste) your CPU heatsink.

I would highly recommend giving us your complete system specs including both make and model numbers. Be sure to include your power supply.

I personally would be having a very hard look at that 10.37 volts on the +12volt supply. I've never seen mine go below 11.7 or 11.8.

Also give us arun down on what you have done maint wise and how old the sys is. Maybe Any recent repair history. I mean you wouldn't go th o the doctor and say I'm broke fix me and expect much help.

After a recent involuntary shut down I powered up and ran the speed-fan program. my system temp was over 120 deg Celsius. My rig is just over 2 years old and consists of :

Antec NeoPower 650 Blue 650W ATX12V / EPS12V SLI Certified CrossFire Ready Modular Active PFC Power Supply

Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775 Quad-Core Processor

COOLER MASTER COSMOS 1000 RC-1000-KSN1-GP Black/ Silver Steel ATX Full Tower Computer Case

EVGA 122-CK-NF67-T1 LGA 775 NVIDIA nForce 680i LT SLI ATX Intel Motherboard

I'm in the process of ordering an upgraded cpu cooler. I've been running stock since I built the computer. Should I/ can I upgrade the other case video and motherboard fans?

I think when the air hits the paste after you remove the heatsink to change things, if it sits there a few minutes, it makes part of the paste harder then it was, making it difficult to spread, and that can create small enough gaps where air gets in there, and creates micro-air bubbles, and that can explain why you can have a hot processor, even if there is paste on it, I know some of the factory paste is not very spreadable.

There are different types of grease, and you might have a type of paste or grease on there where it makes a difference.You need a solvent, 90% alchohol, or goo-remover, lighter fluid, or professional thermal paste solvent, and clean the processor and the heat sink.

You apply a new coat of thermal paste (a straw works wonders, it is nice and round, and can give you an even layer).

Don't put too much, or it will drip down into the pin area when you remove the processor the next time. Dropping the frequency down to 1000 Mhz and no temperature changes is a pretty good sign you need to clean the processor off and put a fresh coat on there. Remember to put the speed back to default settings before you break everything down (or you might forget).

If you haven't already solved your problem, could you post an actual screen shot of CPUID's Hw Mon that you mentioned in your 1st post? It is unclear just exactlly what you are calling ""system temp".

I thought I had a problem once when Everest continually reported one of my temps at like 125degC. It also showed up in HW Mon. Come to find out that depending on your mobo, cpu, and various chipsets, not all sensors are reporting and some may not be fully compatible with your monitoring program. When that happens, the programs will report some rediculously high temp just to get your attention. If your really concerned or just want confirmation for piece of mind, email your board mfr with the "exact" monitoring programs (name and ver nr), and the exact sensor name along with your mobo part nr and rev number. I did this with Asus and confirmed just that.

The temps that I would really be concerned with, is your cpu temps if those are in fact idle temps, you didn't confirm that. That is why the questions concerning the heat sink and paste.

I disagree with mach 9's method of applying thermal paste. I would draw your attention to these 2 links from the overclocking forums as starting points. The first is a really, really in-depth trial on these forums of the IC7 diamond Thermal paste. The folks got down and dirty with the best methods of application. I personally find the rice grain/pea size drop in the middle of a "clean" cpu works every time. I've only been at this a short time but these folks have been at for years and some are professionals. The second link covers direct contact heat pipe type coolers.

Applying thermal Paste to the Hyper 212+

Now about that voltage being reported for your +12v rail. You really need to get that checked out. Either do it yourself with a cheap digital voltmeter or take the psu to a shop. I understand some of them will check it for you for free or next to nothing. that voltage is way to low (I think). I just fired up a game on my Xfired ATI 4890's and played Crysis full eye candy for an hour and my +12v supply stayed steady at 11.93v.

Lastly, back to the cpu cooler. If your not overclocking you really shouldn't need to get a big fancy cooler. If you are in a hot room then just spend 30 on the Hyper 212. the stock should do fine as long as there is no problem with those push pin retainers.

Edit Why won't this damn thing post????

I bought a hyper 212 plus and installed it last weekend. Everything stays around 35 deg cel +\- at idle, except for my 2 8800 gt's. their around 68 deg.

The power supply is at 10.67V. I'll check it out and see what it get with my dmm,
