Ya I know, its a Compaq computer from 4 years ago...5 maybe, I had to get it a new case because my PSU died, and lame compaq made their cases so that only their PSU fit, anyways its a $20 case, as why it is a 35C cpu and 64C case....I have noooooo idea, its badly ventilated, I only have the heat sink fan and a cheap 80mm on side panel facing the heatsink.
