Use something called a CPU cooler. They have it at any reputable PC store or online at Newegg or CompGeeks. They work but make sure you know what you're doing before trying them.
to reduce the heat. its acts as a coolant
to modify the clock speed as needed to reduce power consumption and heat.
Quite simple find out what socket your previous cpu is, buy one that fits your motherboard. To install, remove fan/heat sink. Then remove old cpu, replace it and apply thermal grease, put the fan/heat sink in position and its done.
If you have a laptop and you have vista go to power option and cusimize, otherwise search for a program (and download it) that will do the job for you.
It is important to double check the bottom of heat sink before attaching it to the CPU socket so as to ensure proper insulation. This one of the basic safety precautions in connecting a CPU.
Heatsink compount or special heat pad. The reason for this is to form a tight thermal bond between the processor (CPU = Central Processing Unit) and heatsink for the best transfer of heat away from the CPU.
Most heat is dispersed from the CPU by the heat sink - a large aluminium blob stuck onto the actual CPU. The fan is there to assist in the distribution of heat away from the CPU and into the surrounding atmosphere. So CPU's run so cool - laptops, phones etc, don't have a fan as the CPU's run relatively cool, and the heat generated can be dispersed by convection.
CPU fan is attached together with a heat sink on the mother board, CPU fan is used to prevent overheating of the processor on the motheboard
Thermal grease to allow heat to transfer to the heat sink.
If you hear a long beep sound with no display from CPU.
dissipate heat
what is the function of the heat sink fan? *well the CPU generates heat and in order for the CPU to remain in a safe temperature zone a haet sink is added on top of the CPU.
