If there is room in my usb hub, I'm going to stick small heatsinks on the Erupter's UART (CP2021), the regulator (AOZ1021) and the BE chip (BE100).

My intention is to extend the life of the device by bringing down the overall PCB temperature. The components that get hot may be ok with it, but the whole USB is getting very hot, and all the components will be cooking.

I have a small, quiet USB fan from ebay for $2 that will be running 24/7.

My neighbour has a FLIR camera, when I get my Erupters I will ask him for a picture or two and post them here.

I'll do before and after heatsinks.

Just wanna get my Erupters!
