Oh, and here's an updated pict (before the A6 arrived) of my S5 with the 3D printed parts on (intake fan duct, top and bottom heat sink covers, I did not use the exhaust fan duct) and I added a pull fan.  I also got some clear acrylic side covers because they are neat.  At 400 freq and 60% fan setting it runs about 50-53*C.
