Antminer Dual 120mm to 8-Inch Shroud V4
This Antminer dual 120mm to 8-inch shroud connects both stock exhaust fans to one 8-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.
8-inch outlet
The larger connection provides more duct area for high-volume airflow, especially when a setup has longer runs or bends.
Printed in PETG
Designed and printed by CryptoCloaks in Colorado for the warm exhaust side of Bitcoin mining hardware.

Choose the outlet that matches your duct
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 8-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 8-inch duct and clamp for your installation.
Does an 8-inch outlet guarantee lower temperatures?
No single part can guarantee a temperature change. Results depend on ambient temperature, duct length, bends, restrictions, and external fans. Monitor the miner after installation.
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.
