It can work, I know someone who uses a box fan for a laptop cooler, lol.

But it shouldn't hurt anything at all as long as it don't touch any component inside the computer. But there is always other solutions to fix a Overheating problem then using a box fan which might take up some room.

Ok,i was just wondering. I do plan on buying some components to cool things down. Someone told me before that doing that could lead to a lot of dust build up and stuff. Is that true?
 


Yeah, dust build-up is about the only issue. It'll work wonderfully besides that though, for a short while (I've done it myself before, lol).

Ok,thanks for the reply. Was there anything you used to clean the dust build-up?
