Antminer Dual 120mm to 6-Inch Shroud V4
This Antminer dual 120mm to 6-inch shroud connects both stock exhaust fans to one 6-inch duct. Printed in PETG with the V4 design, it mounts with the miner’s existing fan screws. Use it to route the main ASIC exhaust into a supported duct run rather than leaving it to discharge directly into the room.
Fit rule: This design fits every Antminer model that uses two 120mm exhaust fans. Confirm the fan frame measures approximately 120mm edge-to-edge before ordering. This product does not capture PSU exhaust.
Built for a clean home-mining exhaust path
Both fans captured
One shroud covers the complete dual-fan ASIC exhaust bank instead of leaving hot air in the room.
Stock-screw mounting
Remove and reuse the existing fan screws. No separate brackets or mounting kit are required.
Printed in PETG
Designed and printed by CryptoCloaks in Colorado for the warm exhaust side of Bitcoin mining hardware.

Frequently asked questions
Which Antminer model names does this fit?
Compatibility is determined by the hardware, not a limited model-name list. If your Antminer has two 120mm exhaust fans, this is the correct 6-inch design.
Does it capture PSU heat?
No. This shroud is intentionally designed for the main dual-fan ASIC exhaust bank.
Are the duct and clamp included?
No. The listing is for the printed shroud. Supply a compatible 6-inch duct and clamp for your installation.
Should I choose 6-inch or 8-inch?
Match an existing duct system. When building a new high-volume exhaust route, consider the 8-inch version for more duct area and fewer restrictions from long runs or bends.
Installation note: Never work on an energized miner. Keep duct runs open and supported, avoid sharp restrictions, and monitor temperatures and fan behavior after any airflow change.
Still checking your fan size?
Use the CryptoCloaks ASIC Shroud Finder to choose by brand, fan count, measured fan frame, and duct diameter.

The dual to 6 inch adapter is exactly what I needed for my Antminer window unit. The part was printed perfectly and all measurements were accurate. Bolted on with the existing hardware in under 5 minutes.

I have been a client for a couple of years now. I’m really satisfied with the quality of the work. This last piece that was purchased seems more sturdy than previous models. It looks like it will withstand time and heat really well. Will definitely keep purchasing from cryptocloaks.

Fit like a glove, or should I say a cloak.
