Here are a couple of pictures of the new passive heatsink. Right now besides the pc case fans, I’ve got a desk fan pointed straight at the side of the pc blowing air through the side vent, and another fan at the front of the pc, blowing air into the intake holes. It’s been pretty warm the past couple of days and this room gets very stuffy, but the computer’s been running well with no stability problems so far, so fingers crossed I won’t need to rig up anymore internal fans.
