Added v4 version.
There is new frame for 120x120mm PC FAN to improve suction.
For mounting fan to the frame i have used four pc fan rubber holders, but you can use screws or whatever you want. As BOFA main unit is noisy there is no need to use those rubber holders for damping vibrations, but i have had them around so i just have used them:)
Also small PC fan PWM controller is added so you can choose RPM you need (On/Off switch is integrated to potentiometer). For fan (and PWM controller) 12V 3A PSU is used.
Fan grill is glued to the frame with double sided tape as i wanted "cleaner" design and do not wanted use screws in front section.

I have added round version (v3), it has better efficiency (and better look for me) and it is closer to oiginal BOFA part.
Also i have created small stand for it, you can glue it, screw it or just use it freely withot mounting to anything.
