PSU low profile fan adapter (60mm to 120mm)

Mind you, buying a new power supply unit is probably your best bet, but if you're as stubborn as I am, read on... I wanted to replace my noisy CTC power supply unit fan with a quieter one, but I couldn't find a 60mm 24V fan in my price range that matched the sound levels of normal quiet 120mm PC fans. Since I already had a 120mm fan, I decided to create this adapter to mount it outside over the PSU vent after removing the original fan. You'll need your 3D printer on high feet like mine (see http://www.thingiverse.com/thing:1957836) to ensure enough space. I attached a step-down controller from a 24V power supply to get 12V for my standard 120mm silent PC fan. Even with the adapter's low profile potentially reducing the fan's capacity, the temperature inside my PSU was excellent, even lower than when using the original 60mm fan.

I put the controller in an enclosure (http://www.thingiverse.com/thing:1306586) and cut some connector cable from an old PC PSU with the same type of connector as on the fans.
