[hpsdr] To Fan or Not to Fan

[g4fre at g4fre.com]

running my lpu off 13.8v to power penny, ozy and mercury, after 4 hours on 
receive i can burn my fingers on the lpu heatsink 

I have reverted to my  pico-psu 90 which hardly gets warm under such 
conditions. I dont get noise issues, or none i can notice in my urban 
environment

That was the case until I installoed the LPU which disapates significant heat when left on for extended periods. Assuming that we will be using LPU for a while it seems like a fan for Pandora may be necessary even with out a high output PA.
