Overheating, but wont work with new cpu fan??

Hi Guys,

My pc (approx 2 1/2 years old)started overheating a couple weeks ago, shutting down, fan whirring up and restarting, also showing a cpu temp of about 60deg C. I took the case off and gave fans, case vents etc a going over with compressed air which seemed to fix the problem. A couple nights ago same thing happened and on restarting it couldnt get into windows without it shutting down on me. It will however work fine with the case off so i can only assume its an overheat problem. I picked up a new cpu fan and fitted it today, (no problems like a glove), but on turning my computer on it fired up first time ok for a couple minutes then froze completly. Trying to restart it the only life it showed was the fans going. After a bit of head scratching and beer drinking, I refitted the old cpu fan and it is back up and running again (with side case off),but on start up got a message saying overclocking failed?? Any thoughts? i've changed basic components before and never had anything like this happen. Cpu is Intel Core 2 Q9550 quad 2.83ghz, and if it matter 4gb ddr2 ram, Radeon 4800 series graphics card, 1TB hard drive.

Any advice appreciated

There are two schools of thought on the way a fan should be facing on a cooler, some go for the drawing the heat away others go for the blowing the heat away.There is a third group of which I am a member and that is the push/pull setup with two fans attached to the cooler. But none of these apply to the OP as he is using a stock cooler and the fan is fixed and cannot installed anyway but the right way way.

Are you sure that you have not replaced a three wire (one being a going to a sensor) with a two wire.

go ito your bios and see how the fans xettings r. Double mke sure you have fie#rmly placed the fan sloted onto the motherboard and double check the fan in the power supply as well as the motherboard and the case fan.

Have you reapplied a good thermal paste artic silver is agood one, I remebr when i took off my motherboard fan to give it a good clean i messd#ed up the pins that slooted into the motherbaord which caused overheating to 99c.

Got a new fan and followed the instructions on the box and repllied artic silver.

Juist a thought the case is it a big case or a small case, the bigger the case the better, if you do decide to change the case make sure its comaputible with the motherboard
