The Canaan Nano 3 / Nano 3S Cooler Box turns a messy home-mining stack into a clean, serviceable Bitcoin mining setup. It is built for the regular Canaan Avalon Nano 3 and the Avalon Nano 3S, with 2-unit and 4-unit versions available. Instead of letting tiny miners sit flat on a desk, fight for air, and drag cables everywhere, this box gives each unit a proper stand, a shared airflow path, and cable routing that looks intentional.

This product is the cooler box only. Canaan miners are not included. Choose the 2-unit or 4-unit layout, then select whether you want fans, controller, and an exhaust shroud included. Base pricing starts at $50 for the 2-unit cooler box without fans or shroud. Fan and shroud options change the final price in the selector above.

Canaan Nano 3 cooler box and Canaan Nano 3S cooler box compatibility

The CryptoCloaks cooler box fits both generations Ricky keeps getting asked about: the regular Canaan Avalon Nano 3 and the Canaan Avalon Nano 3S. Canaan lists the Avalon Nano 3 at up to 4 TH/s with configurable power modes and the Avalon Nano 3S at 6 TH/s and 140W. Both are small enough for desks, shelves, garages, offices, and mining corners, but both get cleaner when they are mounted with airflow and wire management in mind.

What this ASIC miner stand fixes

• Airflow: gives the Nano 3 or Nano 3S stack a cleaner cooling path than loose miners sitting flat on a table.
• Wire management: routes power, network, fan, and controller cables instead of letting everything pile up behind the miners.
• Multi-unit layout: supports 2 or 4 Canaan Nano 3 or Nano 3S units in one organized cooler box.
• Optional exhaust control: add a 6 inch or 8 inch exhaust shroud when you want to push warm air away from the shelf or desk.
• Shop-built parts: printed by CryptoCloaks in Colorado for home miners who care what the setup looks like.

Available options

• 2-unit cooler box: best for a small desk, shelf, bedroom, or starter home-mining setup.
• 4-unit cooler box: best for stacking multiple Nano miners in a cleaner garage, office, or shop corner.
• Fans and controller: optional. Select yes if you want a ready cooling package, or select no if you already have your own Noctua-style fan plan.
• Exhaust shroud: optional 6 inch or 8 inch shroud, color matched to the case when selected.

Specs and fitment

• Fits: Canaan Avalon Nano 3 and Canaan Avalon Nano 3S
• Capacity: 2 miners or 4 miners depending on selected version
• Cooling: 140mm fan mount support with optional fan/controller bundle
• Shroud options: none, 6 inch, or 8 inch exhaust shroud
• Product type: 3D printed cooler box, dock, stand, and wire-management enclosure
• Made by: CryptoCloaks in Colorado

Why not use a basic Nano 3 dock?

A basic Canaan Nano 3 dock or Nano 3S stand mostly holds one miner upright. That is better than nothing, but it does not solve the full home-mining mess. This cooler box is made for the way people actually run small Bitcoin miners at home: multiple units, power bricks, fans, controllers, Ethernet or Wi-Fi, and a limited amount of desk or shelf space. The goal is simple: cooler miners, cleaner cables, and a setup that does not look like a science project collapsed behind your monitor.

FAQ

Does this fit the regular Canaan Avalon Nano 3?

Yes. This cooler box fits the regular Canaan Avalon Nano 3 and the Canaan Avalon Nano 3S.

Are the Canaan miners included?

No. This product is the CryptoCloaks cooler box, dock, stand, and wire-management enclosure. Miners are sold separately unless you buy one of the complete bundle listings.

Should I choose the 2-unit or 4-unit version?

Choose 2-unit if you are running a small desk or shelf setup. Choose 4-unit if you already have multiple Nano miners or plan to expand the stack.

Do I need fans and a controller?

If you want the simplest cooling setup, choose the fan and controller option. If you already have your own fan plan, select the no-fans option and use your preferred 140mm fans.

What is the exhaust shroud for?

The exhaust shroud helps direct warm air away from the cooler box. It is useful when the miners sit near a wall, shelf, desk, or window vent path.

Your Avalon Q is dumping hot exhaust straight into your room, raising ambient inlet temps and quietly throttling performance before you ever check the dashboard. The Canaan Avalon Q exhaust shroud from CryptoCloaks is the direct fix: a precision-engineered PETG duct adapter that connects your miner’s rear exhaust to standard flex duct in under five minutes, with zero tools required.

What Is the Canaan Avalon Q Exhaust Shroud

The Canaan Avalon Q exhaust shroud is an in-house engineered duct adapter built specifically for the rear exhaust port of Canaan’s Avalon Q bitcoin miner. CryptoCloaks designed this part from scratch. It is the original shroud for this miner, not a copy of a competitor’s part or a scaled-up generic adapter. The shroud channels hot exhaust airflow directly into a 6-inch or 8-inch flex duct run, so you can push that heat outside, into a garage, or into a dedicated exhaust system.

Without a proper exhaust adapter, the Avalon Q pushes a high volume of hot air into the surrounding space. That heat recirculates as inlet air, raises operating temperatures, and forces the miner to work harder over time. The Canaan Avalon Q exhaust shroud creates a sealed, low-resistance exhaust path that keeps inlet temps stable and your miner running in its optimal thermal window.

Material selection is not an afterthought here. PLA softens at relatively low temperatures and can warp or deform when exposed to sustained hot exhaust from a running ASIC. PETG maintains structural integrity in exactly this kind of thermal environment. CryptoCloaks prints every Canaan Avalon Q exhaust shroud in PETG, not whatever thermoplastic is cheapest or easiest to run on a print farm.

Why CryptoCloaks

CryptoCloaks has been engineering bitcoin mining accessories since 2017. Ricky, the founder, personally designs, prints, and ships every order from his shop. When the Avalon Q reached the market, CryptoCloaks was the first to develop a dedicated exhaust shroud for it. That original design now carries 16 verified five-star reviews, with zero reported fitment issues or heat-related failures across all of them.

The Canaan Avalon Q exhaust shroud mounts directly onto two existing rear screws on the Avalon Q chassis. No drilling. No adhesive. No modification to your hardware, period. If you need to service the miner or move it to a new location, the shroud comes off in seconds. This reversible, tool-free approach is deliberate: home miners need parts that adapt to their setup, not parts that permanently alter expensive equipment.

CryptoCloaks also offers a full catalog of home mining accessories for ASIC miners, so you can build out your entire home mining setup with parts sourced from one proven, bitcoin-native maker. Every product in the line ships from the same hands that engineered it.

How It Compares

The Canaan Avalon Q exhaust shroud is the originator in this product category. Some copies have appeared since CryptoCloaks released the design, and a DIY print file exists on Reddit. Here is a direct comparison of what each option actually delivers:

The DIY Reddit file option requires you to own a printer, source PETG correctly, dial in print settings for a functional fit, and do your own quality control. The competing commercial copy ships an unverified design with no public review history and no named maker behind it. The CryptoCloaks version ships tested, proven, and backed by 16 customers who have already run it on their hardware.

Frequently Asked Questions

Does this shroud fit both 6-inch and 8-inch flex duct?

Yes. The Canaan Avalon Q exhaust shroud is offered in two distinct versions: one with a 6-inch outlet collar and one with an 8-inch outlet collar. You select your preferred duct size at checkout before adding to cart. Both versions share the same rear mounting interface and the same installation process, so the only practical difference between them is the collar diameter. Standard 6-inch and 8-inch flexible aluminum or insulated duct from any hardware store connects directly to the outlet without adapters. If you are unsure which size fits your setup, the 6-inch version suits most typical residential installs. The 8-inch version is the better choice for longer duct runs or where minimizing static pressure matters, since the larger diameter moves the same volume of air with less resistance.

How does the Canaan Avalon Q exhaust shroud attach, and does it require any drilling or tools?

The Canaan Avalon Q exhaust shroud slips directly onto two existing rear screws on the Avalon Q chassis. No drilling, no adhesive, and no tools are required at any step of the installation. The mounting points are the factory screws already present on the back of the miner, so the install does not modify your hardware in any way. The full process takes under five minutes from opening the package to having your flex duct connected and secured. Removal is equally fast. Because the shroud leaves no permanent mark on the miner, it is safe to use on units still under warranty or units you plan to resell. This tool-free, reversible mounting approach reflects how CryptoCloaks designs every product in its mining accessories line.

Is PETG safe to use near the heat output of the Avalon Q?

PETG is specifically well suited to this application. The material has a glass transition temperature well above what the Avalon Q’s exhaust air reaches under normal operating conditions. PLA, by contrast, has a significantly lower glass transition temperature and can soften, deform, or warp when exposed to sustained hot exhaust airflow from a running ASIC. This is not a hypothetical risk: PLA parts have failed in similar applications, causing ducts to detach or seal poorly over time. CryptoCloaks uses PETG across its ASIC accessory line precisely because it holds its shape in thermal environments where PLA cannot. Every Canaan Avalon Q exhaust shroud that leaves CryptoCloaks is printed in PETG, not substituted with a cheaper filament to reduce production cost.

Pick your size, pick your color, and put your Avalon Q’s exhaust where it belongs: outside your room. The Canaan Avalon Q exhaust shroud is in stock, engineered by the team that built the original design, and ships direct from Ricky’s shop. Bitcoin accepted. Made in America. Ships in 2-3 business days.
