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 heak 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 damge 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 collong 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.About The Author
