Clean fans with compressed air

Canister air made for electronics is the best option to clean computer fans and other computer parts. This canned air is static-free, which helps prevent damage to computer parts. Cleaning electronics with canned air is the safest and most economical. Use compressed air to ensure that dust and dirt don’t move around in your computer case.

Clean with electronic vacuum

A small electronic vacuum cleaner or electronic duster CPU cleaner is the second choice. These devices reduce static generation and discharge to protect electronic equipment like canned air.

Be careful when plugging a vacuum into a wall. These vacuums can produce ESD, which could cause damage to your computer. When using these vacuums, make sure to remove the fan.

Clean with a damp cloth

The fan might look similar to the one in this image if the computer is near a smoker. If this is the case, you can moisten a damp cloth with water and rub down the fan. Also, we recommend that you remove the fan from your computer using a damp cloth.
