Every summer my house gets hot, and my PC just made it worse. I wanted a way to collect the exhaust heat from the case and port it directly out the nearby window, and I wanted to not take up too much space doing it. This simple design covers the two fan vents on the top of the case, as well as the upper rear fan and the graphics card exhaust. It has a 4" diameter output designed to interface with standard dryer ventalation hose. Holes have been modeled into the top to allow for the use of 6x2mm magnets. The bottom of the rear portion has been purposely left open to allow the cables to run out. I have provided a full version of this model, as well as a 4 segment version that will fit on a 220mm square bed. For reference, this was designed to interface specifically with my case, which is a Corsair Vengeance C70.
