My guide on how to clean your ENTIRE computer Keyboard, Monitors, Case, Computer, etc.(r/buildapc)
DO NOT use a vacuum cleaner in a computer. You’re just asking for problems since vacuums will generate static electricity.
If you want a good clean computer, buy yourself a Metro Datavac, take your computer outside, and turn it on. You should either uninstall your fans or hold onto them when using it so that they don’t overspin.
