CPU Heating up too fast

Intel Core i7 i7-920 quad core processor

Specs: Windows 7 Professional, 8g Ram
I'm running a new air-cooled computer, which is having super bad CPU Heat problems. The CPU is heating up to 80ish degrees within 5 minutes, while the rest of it is fine. I'm on my Netbook right now, I can't tell what the CPU is exactly, I know it's an i7 quad-core though, and not that 1000 dollar extreme one.

I've got a Thermaltake heatsink, the one that looks like freaking saw blades, and it's securely attached. I applied the thermal compound evenly, used a card to spread it, maybe I put too little?

The fans I have for it: I've got 3 80mm, two on the side blowing air in, and one on the top blowing air out, as well as a 120mm blowing air out the back (And it's right next to the Heatsink, too). There's also the PSU fan, and the Video Card I have also has a fan on it, blowing up, so there's plenty of air movement in the case.

I honestly have no idea what's going on.

"I applied the thermal compound evenly, used a card to spread it, maybe I put too little?"

If anything, you used too much. Use the Arctic Silver instructions for applying paste to the Core i7. They should be followed exactly, regardless of the brand of paste you use:

"The fans I have for it: I've got 3 80mm, two on the side blowing air in, and one on the top blowing air out, as well as a 120mm blowing air out the back"

The side panel fans are useless, in fact, they disrupt the airflow...get rid of them. The top fan is probably unnecessary as well. All you really need is the PSU & the 120mm exhaust fan in the rear.

What are you using to c heck the cpu temps ? Does it heat up to 80 degrees(Centigrade, I assume) while in the bios ?

I agree with Jam. Side fans look nice especially if they are the flashing light variety, but they achieve very little. The idea is to establish an air flow from bottom front to top rear. A side fan will prevent that from happening and just cause pockets of stagnant air.

Jam can you help me? I have been playing a game for a few years and one time i even went to 6 hours straight. But when i send it for repair it came back with heat problems. In 30 minutes it will auto-shutdown

I also have the same problem. I am using a CT-522A model from Compaq(HP) home's edition. I played up to six hours and it didn't heat up. But when i send it for repair it came back with heat problems. Within 15 mins it will shut down

Start your own thread. Explain why it went out for repair originally. Include all details about the problem AND details about the system. OR take it back to where you had it repaired and have them fix it right.
Hijacking another thread for your own question is considered bad manors and many will just ignore it. PLEASE try again.

You have to be a little bit crazy to keep you from going insane.

Besides the thermal paste possibly being too thick, are you SURE you've got the heat sink properly installed; clips properly attached and even pressure across the CPU?

Also, and in line with another comment on fans, if you've got that many fans running in different directions you could be causing the problem. You want a smooth airflow from an intake in the front, across the board and then out the back. Also make sure you don't have a lot of wires etc blocking the air flow.
