I was messing around with my old computer when i noticed my 1.5 foot, around 23 cm(i think, i dont feel like doing real math) for you metric people, fan sitting next to my pc. So putting 2 and 2 together i opened up the side of my pc case and blew that air in there. It cooled my case from 112*F to 58*F. Is there anything bad that could happen rather than more dust from doing this?
