It’s no secret that a desktop PC must be upgraded from time to time if you want to keep up with the latest games. You won’t want to upgrade too often, but replacing the CPU and GPU every four to five years is probably the bare minimum. Of course, this is only necessary if you want to play the most demanding games.
However, replacing a CPU requires some PC-building knowledge; it isn’t as easy as swapping out a GPU (which can also be difficult if you don’t have any previous experience).
If you would like to swap out a CPU, you must clean the thermal compound from both the CPU and the heatsink/cooler.
To ensure the old thermal paste is completely removed, this guide will explain the best techniques to do so.

What You Will Need
Before starting the cleaning process, these are a few things you should have on hand:
- Microfiber cloth – This is best used for cleaning since it leaves no residue and reduces the risk of scratching.
- Isopropyl alcohol – Thermal paste reacts well with alcohol, making it much easier to remove. Alcohol is a covalent compound, meaning it isn’t electrically conductive.
- Toilet paper – Toilet paper is not as soft as microfiber cloth, but it is still a solid alternative. It is great for the first few wipes when there is still a lot of thermal paste.
- Cotton swabs – These are not mandatory but are very useful for the finishing touches.
- Thermal paste – You will need thermal paste to apply when you’re done removing the old batch.
That’s it! If you possess these things, you are prepared to commence.
Removing the Cooler
First things first!
When you upgrade your CPU, take off the heatsink/cooler from your computer.
If it’s a fan cooler, eliminating it is not challenging. Just unscrew the screws at the CPU corners and take it out.
Cleaning the CPU
With the heatsink removed, it’s time to get cleaning!
Grab a little bit of dry toilet paper and wipe away some of the excess thermal paste. Make a few swipes with the toilet paper to ensure you won’t smudge it around later when you use the alcohol.
With that done, you can grab the microfiber cloth. If you don’t have one, you can continue using toilet paper.
Dip a small amount of the alcohol onto the cloth or toilet paper. Making slow, smooth movements, start wiping the CPU. It will usually take a couple of isopropyl alcohol dips for the CPU’s IHS to be completely clean.
Don’t worry about making it pristine, as the thermal paste can sometimes stain the CPU; there is no point in scrubbing it too much.
Finally, you can use a pair of cotton swabs and dip them in the isopropanol to clean all the difficult-to-reach spots.
Next, it’s time to turn your attention to the cooler.
Cleaning The Cooler
If you plan to reuse the same cooler you’ve been using, it is important to clean the thermal paste from the heatsink as well.
The process is practically the same: a few wipes with toilet paper, rubbing with the alcohol-dampened microfiber cloth, cotton swab swipes, and you’re almost ready to start using your computer.
But, wait! First, you need to add the thermal paste to ensure proper thermal conduction between the cooler and the CPU.
Applying Thermal Paste
Putting thermal paste on a processor is easier than people think. But, it’s good to research before starting. Also, having good thermal paste is important for best outcome.
To help you do this, we have an informative and extensive guide on how to properly apply thermal paste to a CPU.
Here’s the short version:
- Remove the cap from the thermal paste syringe.
- Slowly and steadily push the thermal paste onto the CPU.
- The simplest method requires you to apply a pea-sized dot onto the middle of the processor.
- Add the heatsink, and start tightening the screws diagonally to ensure the pressure is as even as possible.
And now you can finally connect your computer and switch it on. Experience the power of your new CPU or the cooling provided by your new heatsink.
