DIY Airflow System for Bitcoin Mining: A Cleaner and More Efficient Solution

Cryptocurrency mining has gained more attention and popularity over the last few years. With people becoming involved as hobbyists or small business owners, it’s important to find ways to optimize mining rigs and create a more efficient system. One such issue that is faced by miners is the dust and dirt accumulation in the filters, which need regular cleaning to ensure proper functionality. In this article, you’ll learn how you can build a DIY airflow system for your mining rig, specifically for the s19j Pro, and how this can improve your overall mining setup.

Why Airflow is Important for Cryptocurrency Mining

Cryptocurrency mining primarily relies on computer chips or GPUs (graphics processing units) that perform the various mathematical calculations required for mining. These units generate a tremendous amount of heat, and if not cooled properly, can hamper the efficiency and performance, leading to failures and loss in mining profitability.

A proper airflow system ensures that these units are cooled efficiently by providing adequate air circulation and ventilation. This helps in maintaining a stable temperature, avoiding overheating, and allowing for optimal mining performance.

Issues with Traditional Fan-Based Cooling systems

A majority of mining rigs come equipped with high-speed and high-pitched fans meant for cooling the units. However, these fans have their own set of issues, such as:

1. They generate a lot of noise, which can be disturbing and uncomfortable, especially in a home environment.
2. Being high RPM fans, they suck in a lot of dust, dirt, and even bugs, causing the filters to clog and require constant cleaning and maintenance.
3. Due to the small size of the fans, the airflow may not be sufficient to cool the entire rig, leading to performance drops and possible failures.

Upgrading the Cooling System with an AC Infinity Fan and a DIY Filter Box

A solution to these problems is to replace the high-speed fans with a more efficient cooling system. One such option is using an AC Infinity 8-inch fan, offering 800 CFM airflow, paired with a DIY filter box. This setup can be specifically beneficial for the s19j Pro, which lacks fans.

Features and Benefits of the AC Infinity Fan

The AC Infinity 8-inch fan has numerous advantages over the traditional high-speed fans used in mining rigs:
1. It is quieter than the smaller fans, reducing the noise levels significantly.
2. It can cool the rig more efficiently, thanks to the increased airflow, calculated at 800 CFM.
3. The fan can be connected to a temperature gauge, allowing it to adjust the airflow based on external temperature conditions, providing further customization and control over the cooling process.

Building a DIY Filter Box for Improved Cooling and Easier Maintenance

Along with the fan upgrade, a DIY filter box can help optimize the airflow in your mining rig while making maintenance easier.

Easy Filter Replacement and Maintenance

With the DIY filter box, after a month of usage, it’s much easier to replace and clean. The filter captures dirt, dust, and bugs, and can be easily removed and replaced when it becomes clogged. This allows for better airflow and prevents overheating in your mining rig.

Improved Air Flow and Cooling Efficiency

A proper filter box ensures that the AC Infinity fan’s airflow is maximized and cooling efficiency is enhanced. The filter box traps the dust and particles while allowing effective airflow, keeping the mining rig at optimal temperatures.


Cryptocurrency mining can be a profitable venture if done the right way. An essential aspect of a successful mining setup is having an effective cooling system that keeps your mining rig optimally functioning. By replacing the traditional high noise, high-speed fans with an AC Infinity 8-inch fan and building a DIY filter box, you can ensure efficient cooling, reduced noise levels, and easier maintenance of your mining rig, specifically the s19j Pro.

With this improved setup, you can relax knowing that your mining rig is functioning at its best, allowing you to focus on your mining ventures and ultimately achieve higher profitability.
