System is saying that CPU fan has failed and shuts system down. I just replaced the fan and heat sync it is still saying this.


Answers :

When you turn the computer watch the cpu fan. Does it turn at all? If it is not turning then there could be a power problem to the power connector on the motherboard. The thermal paste comes in a tube and looks like silicone. It usually comes with the new heatsink/fan combo. Sometimes the thermal paste is already installed on the heatsink. It goes on the surface where the heatsink makes contact with the top of the processor. If this stuff is not on there the cpu may overheat and get damaged. Usually the computer will do nothing if the cpu is burned up. Will not turn on or anything when the power button is pressed. Have you tried to re-set the BIOS? The other fan going out may have caused the BIOS to lock the computer up to protect the cpu from damage. Look on the motherboard for a set of tiny pins with a little tab on it. These are called jumper pins and they should be located somewhere near the watch battery on the board. The tabs needs to be removed and re-installed on opposite set of pins for 10 seconds then placed back onto the other pins.There is usually only 3 or 4 pins max. If you cannot find them you could try pulling the battery out for 10 seconds and then re-installing it. I advise you try the jumper before removing the battery. Make sure you are doing this with the power disconnected.
Thermal paste is applied between the heatsink and the cpu heat spreader or die. If you removed the heatsink to replace the fan you should have applied new thermal paste to the cpu or you may have burned it up. Try clearing the bios like dageezer said. Look for a jumper pin near the onboard battery to clear the cmos.
