At a Glance
Contents: 1× exhaust shroud, 1× PSU adapter, 2× screw set (8 short and 8 long screws), 1× hose clamp
Size options: 8 inch (200mm) or 10 inch (250mm)
Function: Captures hot exhaust air from the hashboards and PSU and directs it into a duct hose
Why an Exhaust Shroud?
Without a shroud, the miner blows hot air freely into the room. The exhaust shroud directs all heat into a duct hose — outside, to another room, or into a heating system. Works with stock fans as well as with external inline fan cooling.
8 or 10 Inch?
10 inch offers less air resistance and is generally the quieter option: The fans have less backpressure to work against and run quieter as a result. Ideal for longer duct runs or bends. 8 inch is sufficient for short, straight runs and is more compact.
