Crypto Mining Shed Update – An In-Depth Look at Hardware and Airflow

It’s been a few weeks since the last crypto mining shed update, and there’s a lot of progress to report. In this article, we’ll discuss the current status of the shed, the hardware that has been purchased, and the airflow system that will keep the mining rigs cool and efficient.

Shed Progress and Upcoming Inspection

The custom lean-to style shed is being built by a local Amish company in Pennsylvania and is expected to be delivered and installed within the next two weeks. Before any work can begin on the electrical system, the shed will need to pass an inspection by the township. During this waiting period, work can begin on setting up the airflow system for the mining rigs.

Hardware and Electrical System Overview

A significant amount of hardware has been purchased in preparation for the crypto mining shed project. Three 30 amp 240 volt power sources will be installed in meter boxes, with 10-2 wiring being used for proper connection. Digital meters will help to monitor and balance power usage for the entire shed. Additionally, a 20 amp 120 volt connection will be installed for outlets, exhaust fans, and potential workspace needs.

Three Trip Lite PDUs will be utilized to provide power for the mining rigs, with 8-amp C13 to C14 connections for ASIC mining. For Internet connectivity, Ethernet cables will be run from an existing garage switch to a new switch within the shed, and then connected to the mining rigs with short three-foot cables.

Airflow and Cooling System

A key aspect of maintaining efficient mining operations is providing adequate airflow and cooling for the rig components. To achieve this, a combination of gable vents, shutter fans, and filter systems will be installed to create a wind tunnel effect within the shed. Initially, 12-inch shutter fans were considered for exhaust purposes, but concerns regarding airflow led to the decision to utilize four 16-inch AC Infinity T16 shutter fans instead, providing a total of 12,000 CFM.

These shutter fans will be connected to AC Infinity Controller 76’s to manage the fan speed based on temperature. The intake for the shed will be handled by six 12×16 gable vents, each containing blue and white air filters that will be replaced quarterly to maintain proper airflow.

Concerns about water being pulled in through the intake vents due to high exhaust rates have led to the potential addition of protective hoods for the gable vents, with a final decision to be made in the coming weeks.

ASIC Mining and Dedicated Airflow System

In addition to the extensive cooling system for GPU mining, a dedicated intake and exhaust system will be set up for an Antminer S19j Pro ASIC miner. An 8-inch inline hood will be mounted to the side of the shed, leading to a small run of 8-inch ductwork and then through an AC Infinity inline MERV filter box. The placement of the inline fan, whether before or after the intake box, is still under consideration and feedback from the community would be appreciated.

After passing through the filter box, the intake air will be directed into a soundproofing box from Cryptology Consulting, which houses the ASIC miner. This box will be connected to 3D printed adapters by Crypto Cloaks, then ductwork, and finally, an exhaust vent mounted on the outside of the shed.

Upcoming Shed Installation and Tour

With the shed expected to arrive and be installed within the next two weeks, the next video and article will provide a tour of the finished structure. In the meantime, any questions, comments, or suggestions regarding the hardware, airflow, and setup of the crypto mining shed are welcomed and can be left in the comments below.

This project has been an exciting and challenging journey, and the valuable input from the mining community helps ensure its success. Be sure to check back for updates and the upcoming shed installation and tour, and hit “subscribe” to stay informed on this fascinating project.

  1. @The Hobbyist Miner

    1) MERV Filter before the motor to protect the motor from dirt – intake hood, filter box, fan ASIC then exhaust.

    2) your plastic discharge vent for the ASIC will restrict the airflow too much better to use the same intake and exhaust hood – you want unrestricted flow as much as possible for maximum CFM

  2. You are not thinking about the air that is being blocked by the filters, if the air outside is 100 degrees you can blow as much airflow across the cards they will all be over 110 due to the dissipation degradation of the heat sinks

    You need to create a hot and cold isle but the cold isle needs to be cooled with air conditioning. If it’s 105 out all your cards are dead no matter how much air flow you have, blowing 105 degrees across the cards is useless

  3. You are going to need way more intakes than those tiny things. Source you some large louvers, with the mess backing, and you will be good to go. I use 6 24WX32L for my 15GH octominer farm as reference, and it is barely enough. I do use a hot/cold isle setup that is mostly sealed.

  4. Excited to see how your shed turns out. Looking to do the same thing. I currently have a mining attic and am running out of space. Getting harder to manage temps in there!

  5. Are you doing any sound proofing of the shed? Even a layer of spray in foam would help with the sound. Of course it also traps heats so double edge sword…

  6. THM awesome update, man looks like it’s going to be one pretty shed! Man I have 12 bitmain BTC miners and I do nothing for the intake, just hot and cold setup, the most important is good exhaust, not allow one bit of the exhaust to enter your environment, large intake on the garage (well shed for you) no support fans to pull anything in just pull cool air from one side and exhaust on the other side..

    However base on the design of that box I can see the exhaust of the miner and the PSU will just heat up that box, if you can seal off the PSU and miner exhaust/fan in that box from the intake area of the box the box should not get hot, some miner design changes would make that sound proof box a ton better .. still you got the right idea, best to get air in/out of that box quickly or make the design change by sealing off the exhaust side of the miner / PSU in the box from the intake side of that box and you are good to go.

  7. I saw a video of a shed a while ago when the intake was just a big grid on the ground it makes a lot of sense the air is cool under the shed (only works if its standing "freely") and the air would get pulled in on the lowest spot

  8. Everyone has an opinion this would be mine. If you put the fan before the filter you would be building up pressure inside that filter possible limiting the air flow by creating a vortex? If you put that fan on the exit side you would be creating a negative pressure (sucking) making air flow possible better.? just a thought…

  9. Great equipment and ideas. My only suggestion would be to bring some of the intake air in through pvc (or some other pipe) which would be underground. This way your intake air temp would be around 70 f.

  10. I did after the intake box mostly because I'm thinking about the lifespan of the fan. So that the air it's pulling is already filtered which should cut back on the dust and debris that may cause issues for the fan.

  11. fan after filter so you dont have to clean it.. ventilation systems have fan after filters and fan on inntake and out air . cfm will change if you dont have 2.
