So I usually open up my computer every other week and use those dust-off cans, or whatever it's called (compressed air). However, it seems that on my GPU underneath the fan the dust seems to be on there a bit "firmer" then dust around the case. Just wondering what I could use to rub it out, or get rid of it. I know to get thermalpaste off my CPU I used isopropanol and the cloth that came with my glasses, same thing for dust off the GPU??
