Two fan shrouds in one set — one for the intake side, one for the exhaust side of your miner. Direct the entire airflow through duct hoses exactly where you need it: outside, into an adjacent room, or for heat recovery during winter.

What You Need This Set For
In standard operation, your miner blows hot exhaust air freely into the room — and draws in unfiltered room air on the other side. With the 2-piece set, you connect both sides to duct hoses. This lets you supply fresh air from outside and direct the heat wherever you need it — outdoors, into another room, or to supplement heating on cold days.
6 Inch or 8 Inch?
6 inch (150mm) is more compact and works for most setups with short, direct duct runs.
8 inch (200mm) offers less airflow resistance — fans run quieter, work less hard and last longer. Recommended for duct runs over 2 meters, bends or continuous operation.

Frequently Asked Questions
Can I cover just one side?
Yes, you can start with just the exhaust side and install the second shroud later. If you only need one side, the single shroud is the more affordable option.
Which duct hose do I need?
A flexible aluminum duct hose matching your chosen size — 150mm diameter for 6 inch, 200mm for 8 inch. Available in our hose selection or at your local hardware store.
Difference from the Universal Set S19-8?
The Universal Set (S19-8) additionally includes a PSU adapter that also ducts the power supply heat into the hose. It also supports operation without stock fans (external cooling with inline fan). This 2-piece set is the straightforward solution for covering both sides while keeping stock fans in place.
Does this set fit the S21+, S21 Pro or S21 XP?
No. These models use 140mm fans instead of 120mm. Find the S21+/Pro/XP set here.
