Anet A8 Controlboard Case with 70mm Fan
thingiverse
I'm using a 70mm fan from an old computer to cool the controller board of my Anet A8. The fan lowers the temperature of the onboard MOS-FETs by ca. 10 degrees. So, I don't see a need for addional MOS-FETs any more. FreeCAD v0.16 source files included. Feel free to modiy to your needs.
