Wanhao PSU vented cover

thingiverse

I added the Wanhao 120mm PSU cover http://www.thingiverse.com/thing:1590987, but still had a lot of noise from my power supply fan. The 120mm should provide enough airflow for control box and power supply, so I took the cover the power supply and removed the fan. I replaced the cover with this vented cover to keep stray wires out of the power supply and to keep a good airflow. There is a 3mm thing version of the case hooks and a 1mm version. I used 3mm, since I wanted to have a more solid cover. I just bent out the tabs on the case to hook into the hooks. Messing with a power supply will void its warranty and contains a risk of shock. Be very wary of this upgrade and only do it if the unit is unplugged from power and you know what you are doing. Make sure to transfer your wiring diagram sticker from the old cover to the new cover if you want to keep the diagram. I included the 123d files if you want to tweak.
