[time-nuts] PRS-10 heatsink design

[James Wilson]

My limited experience with the factory heatsink for the PRS-10 has left me pretty unsatisfied. It seems ok for brief bench evaluation but not for permanent enclosure installation. Reported unit temps are in the 70 - 75 °C range with it sitting on a bench in a 25 °C room. It needs to be turned on its side or upside down for any convection to take heat away, or for fans to be directed at the fins. There are no side or top screw holes on the PRS-10 so you can’t mount it in that orientation. Has anyone found or built a better heatsink that can use active cooling?
