Ive been testing the performance of fans and have some really interesting data. Compared the Attwood Turbo 4000 blower to the 140mm and 120mm Noctua 3000rpm fans. 
The data i got yesterday was not what i expected, so i tested it all again today a second time.
Heres a video from yesterday still early in the testing. This is the Attwood blower. While getting 13.5v input it was able to dim down to 0.25amps on lowest PWM setting. I had not tested the computer fans at this point.
