Post How To Change Your Computer's Heat Sink
How To Change Your Computer's Heat Sink
by: Otis Cooper

Everyone really want a fast hot computer when we want to do some business computing and when we want to play those high speed games.But we don't want a fast and Hot computer in the literal sense.

Heat will destroy any computer component if not removed in time.And the CPU Chip is one of the main components of your system that produces heat.

The heat sink has the all important task of keeping the CPU Chip cool so it does not overheat.And there may be times when the heat sink will fail to perform its job and must be changed.

Changing the heat sink on your central processing unit or CPU chip is a simple job.And the best part is that you only need a small screwdriver,cotton swabs,and some rubbing alcohol.

To change the heat sink remember to think safety first.This means that you want to be sure you have clean hands,a clean work place,and removing all static charge from your body by touching a door knob or any other metal object.

Once you have a suitable work area and clean hands you should now have a clean suitable mind as well. Allow this task to be both educational and fun.To change the heat sink perform the following.

Step 1.Unplug the computer and remove the cover from the System Unit case.

Step 2. Find the CPU Chip and the heat sink will be on top.Find the wires that go to the motherboard and very carefully unplug them.

Step 3. Remove the old heat sink and cooling fan assembly.Most Pentium based computers will have two levers that lock the heat sink in place.

On older Pentium computers,the AMD Athlon and the Duron processor,look for a ZIF or Zero Insertion Force socket where the processor is mounted.

Gently release the clips by sliding a very small screwdriver blade underneath it and lift the heat sink off the CPU.Take great care here do you don't damage the cpu chip in any way.

Step 4. Once the old heat sink has been removed, clean away the old thermal paste using cotton swabs and rubbing alcohol.Allow time for the CPU to dry.

Step 5. Grab some thermal paste and squeeze a little onto the top of the CPU.Only place enough to have a thin layer between the CPU and Heat Sink.

Step 6. Before installing the new heat sink, clean the bottom off with some warm, soapy water. Check to be sure the Heat Sink is dry before installing it.

Step 7. Carefully line it up over the ZIF socket and processor if so equipped.If the computer have the newer Pentium or Athlon based chip,lock the two clips holding the assembly.

Step 8. With the CPU and heat sink firmly in place, now its time to re-connect the fan wires for the cooling fan.Plug the assembly into the motherboard.

Step 9. Check,double check,and after that,check some more to be sure all connections are in place.See if the heat sink assembly is well secured in its socket.

Step 10. Now replace the system unit cover,plug any peripherals you disconnected.Start the PC and the computer should now realize it has a new device in its system.

Once the computer has been booted up,check to be sure the Operating System is working.If possible, look at rear of the computer to see if the fan is operating as it should.

The Central Processing Unit is not the only heat producing component in your computer.But since its the brains of any computer,you want to be sure the heat sink performs at its best.

Take the time to learn this procedure in detail by removing the case and looking at the heat sink in your own computer.Knowing how to perform this task can save you money should you need to change your heat sink in the future.
