This is great Fred!
I was able to add the always on fan without major mechanical effort (I had to drill a couple holes for the rubber isolation stakes in the heat sink cover sheet metal). If you care take a look in the Files->Mod section for my writeup. Can't hear the always-on fan running, and the primary fan only comes on when I am working a digital contest (like the RTTY Roundup with begins in a few hours).
