Raspberry Pi 4b CryptoMining Rig

thingiverse

Remix of nirmaljangid's design. Just made a small change by increasing the spire height to allow for a standard 4010 fan to cool the pi. Edit 8/24/2021 - Added a new frame that holds the Cooling Tower in place. See new photos of white rack with purple frames. You only need a couple per rack to hold securely Edit: 11/18/2020 - Added a fan mount for the Fram_40 stack. Keeps the fan off of the micro SD card. Added two images showing both versions in full build mode. Edit: 11/17/2020-Added a flat top part, simply for aesthetics Edit: 11/16/2020- Added a Cooling tower for the original short spire design. One fan to cool all four Pi's in the stack. Uses a standard 4010 5v fan (I use this one: https://www.amazon.com/gp/product/B0836QHNTN/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 ) The tower sits behind the rack, I have it attached with double sided foam tape just to secure it. My testing: Ambient Room Temp 80F (26c) Using the redesigned Holder with tall spires for 4010 fan: Pi4 with full top heatsink (no fans) 129F (53c) Pi4 with full top heatsink (w/ fan) 104F (40c) Using the original Holder and the Cooling Tower with one 4010 fan: Pi4 with full top heatsink 113F (45c)
