Re: µB FT8 Success!

I went a slightly different direction and picked up a cheap temp fan relay from Amazon:

I superglued the probe to one of the finals heatsink and then played with ON temp and hysteresis temp, I settled on 50deg ON and 35deg OFF.  It was $5 for the fan relay + probe and ~$8 for a 12v 2wire fan.  Works great.
