How to Clean PC Heatsink
There’s more than one way to clean the PC heatsink, but the simplest way involves taking it out of where it’s installed then put it in hot soapy water. Let the heatsink soak for a while, especially if it has caked-in dirt. Actually, manually remove the caked-in dirt first then wash the rest in the water.
After soaking, rinse off then get some good flow between the heatsink fins to get rid of the sticky gunk for sure. Let the heatsink dry for a whole day or so. You should be good to go afterwards.
What about “Dry” Cleaning?
If the heatsink isn’t as dirty or doesn’t have as much wet gunk on it that requires watery rinsing with “extra wet” soap water (soap breaks down water surface tension that allows it to rinse things better or mix with things like oil), you “dry” clean your heatsink with a blast of compressed air.
- Disassemble: It’s better to still disassemble the heatsink then blast it with a can of compressed air so that the dust doesn’t end up in your other sensitive PC components like your motherboard, video card, sound card, graphics card, CPU, and so forth.
- Vacuum: Many guides warn against using a vacuum because it can eventually damage your PC rig when push comes to shove. You can use it lightly on your keyboard or to clear dust in your table, but your PC parts might suffer from vacuuming.

It Depends on How Dirty the Heatsink Is
It’s safe to clean your heatsink with soap and water, but have the common sense of taking it off the motherboard and CPU first! We’re stating this commonsensical fact regardless because some people are true novices about this and might actually put running water on their PC!
- Spray Quickly: It’s also fine to take your PC case outside every month to spray compressed air in multiple angles. To avoid dust-based scratching, you should spray the air into the fans and vents briefly or not to long, which makes them spin up too fast and get damaged.
- Use CPU Cooler Spray: Instead of using compressed air for your heatsink, you should instead spray what’s known as the CPU cooler spray. Also spray briefly at different angles to get the dust out of the gills of your heastink.

Does dust affect PC performance?
The build-up of dust can (and surely does) impact your computer’s performance for two main reasons: it causes the components of your computer to retain heat and it makes it more difficult for the internal fans to dissipate heat from the system, thereby decreasing the efficiency of the entire system.
The Final Judgment
You might need to only clean the heatsink but you might as well clean the fan along with it for good measure. You can save a lot of money on labor by learning how to do this yourself. Or you can have a technician teach it to you. Otherwise, have someone you trust do it at an affordable price.
It’s pretty simple to do when push comes to shove but many non-tech-savvy people who don’t know how to take apart and put back together their PC will have someone else do it for them.
