how do i clean inside my pc?

can i use something like a small paintbrush?

that would work. i personally use a shop vac on reverse and blow all that dust away do this outside though as it will make a mess inside. only caution is to hold any fans still while blowing directly on it so the fan does not break. spinning it to fast with the air can break the fins or the motor itself.

once bulk of stuff is out then the paintbrush or whatever else can do the detail work for you.

i do this a few times a day and it works great for me. never know how long it's been since a client has cleaned inside their pc (if ever) before they bring it to me to fix!!
