Lenovo K300 Series 120mm Top Fan Mount

thingiverse

This will replace the "handle" on top of the Lenovo Thinkcentre K300 series desktops with a 120mm fan. The graphics card in this K330 was replaced with a gtx 1060 and due to the poor airflow the whole case became warm to the touch and cpu and gpu temps under load were getting too high. The handle comes off without too much trouble by bending back the plastic tabs inside the case and pulling up on the top layer of the handle. There are a few phillips screws under the top layer that also need to be removed before the entire plastic part can be removed. Then drill out the aluminum rivets holding the metal box inside the case and a perfect 120mm case fan opening is revealed. The mount sits perfectly inside the indentation in the case and the fan clamps the whole thing tight when screwed together.
