Whatsminer PSU Capture Shroud: Route Every BTU Out of Your Mining Space
Slip-on fan shrouds only solve half the problem. Your Whatsminer’s power supply keeps dumping heat into the room while everyone looks the other way. This Whatsminer PSU capture shroud from CryptoCloaks captures both exhaust streams at once, so your duct run is actually doing what you built it to do.

What Is the Whatsminer PSU Capture Shroud
The Whatsminer PSU capture shroud is a 3D-printed PETG duct adapter built specifically for MicroBT Whatsminer machines. It wraps around both the miner fan output and the integrated power supply exhaust port, combining those two heat streams into a single 140mm output. That output then connects to either a 6-inch or 8-inch duct run, letting you direct the full thermal load wherever your setup requires.
Generic fan shrouds sold on eBay and Amazon target only the miner fan exhaust. The PSU exhaust port sits right next to it, running just as hot during continuous operation, and it gets ignored completely. CryptoCloaks designed this shroud with a dedicated PSU capture section that closes that gap. The result is a cleaner thermal profile for your mining room and a more effective duct run from day one.
This design is tested on the Whatsminer M30s and Whatsminer M50s. Both models share a compatible fan and exhaust port layout, which is why the shroud fits either unit interchangeably without modification. M20s compatibility testing is currently in progress, and CryptoCloaks will update this listing once that confirmation is complete. For M30s and M50s operators, however, this is a verified, out-of-the-box fit.
The choice of PETG over PLA matters here more than it might seem on paper. PLA softens and begins to deform at temperatures that ASIC exhaust reaches routinely during sustained operation. PETG holds its structural shape under that same heat load. A shroud printed in PLA that sits against a running Whatsminer is a liability. A shroud printed in PETG is a long-term fix.
Why CryptoCloaks Builds the Right Whatsminer PSU Capture Shroud
Ricky founded CryptoCloaks in 2017, back when home bitcoin mining was a garage-and-extension-cord operation. He picks, prints, and ships every order himself from his shop in America. That means the Whatsminer PSU capture shroud you receive is not a warehouse-stocked generic unit. It is a purpose-built part made by someone who has worked with this hardware for years and knows exactly what a running Whatsminer puts out.
The mounting design is intentionally simple. No extra screws, no aftermarket brackets, no sourcing hardware before you can even start the install. The shroud uses the stock screws already attached to your Whatsminer unit. CryptoCloaks engineered the mount points around existing hardware so that setup stays quick and repeatable. That is a deliberate product decision, not an accident, and it separates this shroud from generic alternatives that arrive missing critical hardware.
Additionally, CryptoCloaks offers two duct connection sizes rather than locking you into one. The 6-inch option works for standard residential duct runs. The 8-inch option handles higher airflow demands or longer duct paths. Choose the size that matches your current infrastructure. If you are building a new exhaust run from scratch and want a complete solution, pair this with the Whatsminer slip-on exhaust fan shroud for a fully integrated duct system across your setup.

How It Compares
Searching for Whatsminer cooling accessories on eBay or Amazon turns up mostly whole-unit miner listings and a handful of fan-only shrouds. None of them address PSU exhaust. Here is how the Whatsminer PSU capture shroud stacks up against what else is available on the market right now.
| Feature | CryptoCloaks | Generic Competitors |
|---|---|---|
| PSU heat captured | Yes, dedicated PSU capture design | No, fan shrouds only capture miner fan exhaust |
| Extra hardware required | None, uses stock Whatsminer screws | Often requires separate bolts or brackets |
| Duct size options | 6-inch and 8-inch | Typically single size only |
| Material | PETG, heat-resistant | Often PLA, warps under sustained heat |
| Model-specific fit | Tested on M30s and M50s | Usually listed as universal or unverified fit |
Frequently Asked Questions
Does this shroud fit both the Whatsminer M30s and M50s without modification?
Yes. The Whatsminer PSU capture shroud is tested on both the M30s and M50s and mounts without any modification to the miner. Both models share a compatible fan and PSU exhaust port layout, which is why CryptoCloaks built this shroud to serve either unit interchangeably. You do not need to drill, cut, trim, or adapt anything on the shroud or on the miner. Line up the mount points, use the stock screws already on the unit, and connect your duct. That is the complete installation. If you run an M20s, compatibility testing is still in progress. CryptoCloaks will update this listing as soon as that confirmation is available. For M30s and M50s operators, this is a verified direct fit that takes minutes to set up.
Do I need to buy any extra screws or brackets to mount this shroud?
No additional hardware is required. The Whatsminer PSU capture shroud mounts using the stock screws already attached to your Whatsminer unit from the factory. Those screws are present on every M30s and M50s. CryptoCloaks engineered the mount points specifically around that existing hardware, so the installation process requires nothing from a hardware store. Generic shrouds available on Amazon or eBay frequently list separate bolts or aftermarket brackets as required accessories, which are not included in the product price. That adds both cost and setup friction. With this shroud, everything you need arrives in one package. Unbox it, align the mount points, fasten with the existing screws, and connect your duct. Nothing else is needed before you run.
What is the difference between choosing a 6-inch and 8-inch duct size?
The duct size you select at checkout should match the duct run you already have or plan to install. The Whatsminer PSU capture shroud is available in both 6-inch and 8-inch connection sizes. A 6-inch duct is the more common choice for residential and small-scale setups, easier to route through walls, ceilings, or tight spaces. An 8-inch duct moves a higher volume of air and performs better in setups with longer duct runs, multiple miners sharing a single exhaust line, or environments that need maximum airflow capacity. Neither size changes how the shroud mounts to the miner itself. The difference is only at the duct connection point. If your infrastructure is already in place, match what you have. If you are building a new run, 8-inch provides more headroom as your operation scales.
The Whatsminer PSU capture shroud is the only purpose-built option on the market that captures both miner fan exhaust and PSU heat in a single unit, at $29.99, using your existing screws, in PETG that holds up to continuous operation. If you want complete exhaust management for your Whatsminer M30s or M50s, this is where you start. Bitcoin accepted. Made in America. Ships in 2-3 business days.
