The complete set for your Antminer — intake, exhaust and PSU adapters in one box. Two use cases with one set: Either with stock fans for duct connections on both sides, or without fans for external cooling with an inline fan. You don't need to decide beforehand — all parts for both setups are included.
At a Glance
Contents: 1× intake shroud, 1× exhaust shroud, 2× intake adapter (short + long), 1× exhaust PSU adapter, 2× screw set (16 screws each), 2× hose clamp
Variant: size selectable in 8 inch (200mm) or 10 inch (250mm), PSU distance selectable in 30mm, 60mm or 90mm
Use case 1: With stock fans — ducts on both sides, PSU heat captured as well
Use case 2: Without fans — external inline fan on intake side, exhaust via duct hose
Option 1: With Stock Fans
The fans stay in the miner. On the intake side, the shroud with the long intake adapter mounts over the fan and supplies fresh air via duct hose. On the exhaust side, the shroud together with the exhaust PSU adapter captures all the heat — hashboards and power supply — and directs everything into one hose. This way 100% of the heat goes exactly where you want it.
Option 2: External Cooling
The stock fans are removed entirely. On the intake side, the short intake adapter is mounted and a quiet inline fan plugs directly into the opening. On the exhaust side, the shroud with exhaust PSU adapter ducts the hot air away through a hose. The result: significantly less noise with equal or better cooling performance. Additionally required: inline fan and fan spoofer.
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.
Which PSU Distance Do I Need?
The PSU adapter bridges the gap between the hashboard fan and the power supply. This distance varies by miner model:
30mm — S19 Pro
60mm — S21, S19, S19k Pro, S19 XP, S19j, S19j Pro, S19a, S19a Pro (most common)
90mm — older S19 models (measure if unsure)
Not sure? Measure the depth difference between the PSU housing and the hashboard housing on the front side of your miner. Or contact us — we'll help you choose the right variant.
Compatible Miners
Fits all Antminer models with 2× 120mm fans: S21, S19, S19 Pro, S19k Pro, S19 XP, S19j, S19j Pro, S19a, S19a Pro.
Not compatible with S21+, S21 Pro, S21 XP (different fan size, 140mm) and not with T21 (different case).
Material and Quality
Made from PETG — heat-resistant, durable, and printed as solid material. Designed and manufactured in Germany.
Frequently Asked Questions
What's the difference from the regular 2-piece set?
The regular 2-piece set has no PSU adapter — PSU heat exhausts freely into the room. This universal set captures all heat including the power supply. It's also suitable for external cooling (without stock fans).
Do I need a fan spoofer?
Only for option 2 (external cooling). When you remove the stock fans, the miner reports an error. A fan spoofer emulates the PWM signal so the miner continues to run normally. For option 1 (with stock fans) no spoofer is needed.
Which duct hose do I need?
Two flexible aluminum duct hoses — one for intake, one for exhaust. Diameter matching the selected variant: 200mm (8 inch) or 250mm (10 inch). Available in our hose selection or at your local hardware store.
How do I find my PSU distance?
Measure the depth difference between the PSU housing and the hashboard housing on the front side of your miner. Most miners have 60mm. S19 Pro has 30mm, some older S19 models have 90mm. If in doubt, contact us with your miner model — we'll tell you which variant fits.
Installation guide available?
Yes — an illustrated guide for both setup options is available on our instructions page.
