I have bit of a cooling problem

My CPU is not cooling down properly.
I am using CoreTemp to measure my CPU load and temperatures.
My CPU is idling at around 57- 58 C. When it runs at 20-40%, it runs in the lower 70s. Any higher CPU load and I get anywhere from 76-84 C.

My computer has 3 case fans(I believe they are 120mm), one on top, one behind, and one in front. It has a large vent opposite the CPU fan/heatsink. It sits on a carpeted floor, but has several sheets of thick cardboard underneath it. It is also underneath a desk, but all case fans and the vent have at least 4-5 inches of clearance from the sides of the desk.

I built my computer around 4-5 years ago, and I am still using the fan/heatsink that came with the CPU. My CPU is an AMD Phenom II X4 960T @ 3Ghz. I have never applied thermal paste to the CPU or heatsink. If it means anything I also run Windows 7 home 64 bit, Service Pack 1.

I just dusted out my computer yesterday. I don't dust it out as religiously as I should, because canned air is expensive, but I have been doing it more than I used to.

For the first couple years I had my computer, the temperatures would stay in the 30s for idling and browsing the internet, and if I ran a program like Flight simulator X or some other game, it would go into the 40-50s. Now I don't open any game because I don't want to overheat my computer. If I browse the internet it will go into the 60s, if I run any computer program that puts 30% or higher CPU load I will get 70+.

What can I do to get the temperature down to a more comfortable level?

PS my CPU is at 56 now that I have been typing a while, but that when the computer has been basically idle for 5-10 minutes.

remove the heatsink from the CPU and the fan from the heatsink. CLean all around the fan, and remove the old thermal paste from the CPU (remove it as well) and heatsink using surgical spirit and hard paper towel. reapply CPU, heatsink and fan, you will notice a big difference in temps, let us know how you get on.
 


I'll second this idea. Stock thermal paste can dry after a few years.

Clean it with alcohol and use a lint free cloth on the final wipe. Something like eyeglass cloth works well.

Use quality replacement paste and don't apply too much. A pea size drop in the middle of the CPU is plenty.

Also make sure dust hasn't built up on the heatsinks and fan openings / filters.
