New miner her, just bought 2 x NewPac in addition to the 2Pac I already got last week.  I'm enjoying the potential modding possibilities here as a pet project and wanted to ask if anyone can share experience in replacing the heatsink or other fun mods?  I would rather not try to drill a hole in aluminum, I'm a horrible driller and have an old corded drill.  I think my options are either a single hole or using thermal adhesive compounds, not sure if there is enough surface area on the chip to hold a bigger heatsink.

My experiment is putting these stick miners completely on mini solar panels with the Pi Zero W and see what they can do.  So far I have the Pi Zero W with the current 2Pac running at around 4-5w at the wall,  waiting for solar panel and meter (and NewPacs) to measure more accurately DC draw.

Some discoveries of interest are the Pi 3b has a current limit,  was only able to go to 143Mhz before power maxed out, on the Pi Zero I actually got it to hit 300Mhz and was drawing 12w from the wall.  Got scared was gonna burned out my Pi Zero and turned it back down,  but interesting nevertheless that the Pi Zero will pull a lot more power and apparently as much as you can give it.  That's why a larger passive heatsink is something I'm pursuing.  Also, found out the Pi 3b has a controllable USB HUB, you can use uhubctl to turn off power to the port.  My plan was to put some solar panels on the back of my car and program a pi to automatically turn on/off mining as it detects open Wifi signal, or go into power saving mode by turning off the ASIC.

If anyone has any experience or suggestions to share, would appreciate it.
