Asus AC86U router fan housing

thingiverse

Housing to hold AC Infinity S5 USB fan to cool the Asus router. Print with the lip up so that you don't need support. Unscrew the four rubber legs from the Infinity fan then slip the fan into the housing then screw those legs back. The two antennae go through the top holes. The second version is thinner. I cut out the back of the router with an oscillating tool to get direct access to the heat sink. It is better but still could not cool beyond 55. I tried to take out the heat sink and add the thermal compound and it helped a bit more. However, there is limit if the room temperature is 80+ degrees.
