Post a Video

I'd like to see this fan spin on 45-60C 12s packs for a couple of minutes to be sure of the precision of this fine fan. They should make a video and share it so we can see and hear the sound.

Looks great. Jim put that sucker on a profile with some ducting and huck that sucker.

Yes I just saw that and then I realized the motor shaft is sticking out about a 1/4" which is great for chaffing your wires. Someone needs to get a dremel and some tape. One of the best tools ever created Dremel.
