I was just thinking, if you generally haven't looked inside the case of your computer, there's a very good chance you've got a ton of dust in there and I'd bet even money or better that its your problem. I forgot about this until just now, but last winter I had basically the same problem you had and after investigating a bit I realized my fan wasn't running at all. I started looking into new fans (and possibly new computers as well. My computer is only a little older than yours, but I bought it refurbished for like $500) but realized the fan was completely coated in dust. Blowing off the dust and fiddling with it a little got it back up to running like normal.

Even if dust is not clogging the fans completely, its probably all over everything, both making them less effective and also insulting your components, keeping them from bleeding off their heat. Try picking up a can of compressed air from J&R or Staples or where ever and using it on your motherboard, fan and just about anything else that looks dusty. They work surprisingly well and are fun to play with. Might want to cover your mouth/face if things are really bad, though.

If you haven't dusted your computer ever expect a large amount of bullshit to blow out. The most important thing to dust is going to be the cpu's heatsink. The heatsink will look something like this.

Heat is soaked up into the aluminum fins and the fan then blows air through the space inbetween them to dissipate the heat. If there is a bunch of dust between the fins then you aren't going to have the air flow you need to remove the heat. Start by dusting this son of a bitch out very thoroughly.

Yeah, I cleaned out the dust on the heatsink/fan last night, computer wouldn't start for a while. Let it sit overnight, and it boots up but still sitting at 100C during idle.

Going to try reapplying the thermal paste between the CPU and heatsink, and if that doesn't work I'll just get a new heat sink. And if that doesn't work I'll probably need to replace the CPU. Blargh.

If you go aftermarket I would suggest this guy. It's what I recently upgraded to on my cpu and was able to overclock from 3.2ghz to 3.8ghz and still have lower temps than the stock heatsink. The stock one is a major piece of garbage and should be replaced anyways because of how hard it sucks.

A new CPU won't help the fact that it's overheating. If the problem isn't heatsink/fan related my next guess would be the motherboard being screwy and not setting the proper voltage for the cpu. I think that cpuz can show you the voltage that your processor is running at. Check this against the stock voltage and make sure it's not too high.

Computer's already starting to crap out, so not looking good for being reliable tonight.

been running on windows xp and a 65 dollar best buy video card for like 3 years now.

you kids and your fancy heat sinks and big numbered video cards.

I've been tinkering with the BIOS, and ended up disabling hyper-threading and shutting down 2 of the cores. Has me down to 85C, so might be stable enough to at least stay online for raids until I get this crap resolved. Radio Shack didn't have any Arctic Silver 5 so I ordered some from newegg, hopefully should be here by Friday.

Keep hyperthreading on. It won't effect heat. Hyperthreading is there to balance work between cores. Also 85C is still processor damaging hot.

Eh, HT seems to make the i7 920s run hotter, by about 10-20 degrees depending on what it's doing:

What kind of case do you use sobie?

I would recommend this for your CPU
Corsair H60

get an extra 120mm fan and run 1 Fan on the back of your back fan grill pushing air in through the radiator and another on the inside pulling air through it. My I7 930 runs maybe 40-45c during full loads with this cooler and a full size tower so it has to be an issue of thermal paste/poor stock fan/small case with bad airflow.


also most video cards are set to ~40% fan so for anyone having heating issues with their cards I highly recommend using MSI Afterburner
this allows you to change a number of things on your video card however I would not advise anyone to touch voltage or clock speeds. I use this to change my fan speeds depending on what i'm doing. It also allows you to have on screen display of your card temps while in game so you don't have to go out of game to make sure your video card isn't getting too hot.

This is the case I use: http://www.newegg.co...N82E16811146054

Apparently I can add more fans, but I think replacing the heat sink will do the job. I don't overclock it and I'd prefer to keep the noise down as much as possible. I did overclock the GPU a bit (6950 2GB that I unlocked to a 6970) and it runs fine for most games, I was getting great frame rates in WoW until this heating issue - I think it's throttling the processor so it doesn't shut off.

case looks good, full size tower case is the only way to go in my opinion, extra room helps a lot with the heat. If you are planning on replacing the cooling on your CPU I would definitely urge you to go with the H60 or one of the Hxx series Corsair coolers, they are pretty much silent and take up little space really just the small unit on your chip and the hose running to the radiator panel that goes on the back vent.

So I finally got around to replacing the thermal paste and now I'm around 50 degrees with WoW, chrome, VLC, etc. going. Back to 50 fps in org and 150-200 flying around, woot.
