BTW, I still have all the parts for a LM2575-ADJ adjustable stepdown converter if you want them.

I did find some of the LM2576HV Chris was talking about on ebay for fairly cheap. But I kinda wanted to get what I have working, since, well you know, I have them

Well... actually one less now
 The LM2576HV i have works well, stays cool, and is able to step down from 48VDC. Most of the other dc/dc converters are limited to ~36v, but the biggest selling point is that they come pre-assembled.  Here's that schematic for the fan.

Hmmm, pic is too small to make out. I tried saving it and zooming in but it went all blurry... unless that's the aftermath of the exploding transformer

lol.... sounds like Bill Clinton. Tranformer smoked, but I didn't inhale. Why is everything so blurry?

Nope, didn't inhale. No really...
 Well I had a few minutes tonight so I finished soldering up one proto board and hooked up one of my waterproof temp sensors. After figuring out the address of it, modifying and re-laoding the sketch, all works well
