FYI, ordered a few more from SWC tonight:


Hoping the delta follows a similar good cfm/dbA routine of it's VHE counterpart, and the other two for some additional PWM options. I've been working on my PWM controller, the 4 pin is working great (Modified it with a 5V VRM so I can just feed it 12V only) and now I'm attempting to build a 3 pin version to hopefully try if all goes well.

This is the 3pin PWM version I'm going to attempt...
