Your miner is not the problem. Where the hot air goes is.
If you run a Canaan Avalon Q at home, a proper exhaust path is one of the cleanest upgrades you can make. This guide shows what a Canaan Q exhaust shroud does, how to choose 6-inch vs 8-inch, and what matters before you buy.
1674W air-cooled
~5,712 BTU/hr
$24.99 shroud
Canaan’s official shop lists the Avalon Q at 90T, 1674W, and 18.6 J/T with air-cooling. A miner pulling 1674 watts is also dumping roughly 5,712 BTU per hour of heat into the space around it. If you let that exhaust blow straight into the room, the miner is not just heating the room up. It is also heating the air it has to breathe next.
That is exactly why a Canaan Q exhaust shroud matters.
A proper shroud gives the Avalon Q a clean exhaust path into standard ducting, so you can route that heat out a window, into another exhaust path, or away from the room instead of letting it recirculate around the miner.
What a Canaan Q exhaust shroud actually does
A Canaan Q exhaust shroud is a duct adapter designed for the rear exhaust side of the Avalon Q. Its job is simple:
- capture the miner’s hot exhaust air
- transition that airflow into round flex duct
- let you move that heat somewhere more useful than the room the miner sits in
Without a shroud, the Avalon Q is pushing a high volume of hot air directly into the surrounding space. With a shroud, you get a controlled exhaust path instead of a heat cloud building up around the machine.
Why this matters in a home setup
On a home miner, airflow management is part of the setup. It is not some optional add-on you think about after the room starts getting miserable.
If the exhaust stays in the room, your ambient temperature rises. When room temperature rises, inlet temperature rises too. That is the opposite of what you want on an air-cooled miner.
That is why home miners keep looking for the same things:
- window vent setups
- garage exhaust routing
- short, low-resistance duct runs
- properly sized shrouds that actually fit the machine
- inline fan pairings for longer or more restrictive runs
Those are the real buyer questions around the Avalon Q, and they are exactly what a good shroud is supposed to solve.
- Will this actually move heat out of the room?
- Should I buy the 6-inch or 8-inch version?
- Do I need an inline fan too?
- Does it fit cleanly without hacking up the miner?
What to look for in a Canaan Q exhaust shroud
1. It should be made specifically for the Avalon Q
A generic duct adapter is not the same thing as a shroud designed around the actual rear exhaust port of the Canaan Avalon Q. Fit matters. A loose or sloppy fit means worse sealing and worse airflow control.
2. It should use the right material
This is not a decorative print. It lives on the hot exhaust side of a running miner. The current CryptoCloaks Canaan Avalon Q Exhaust Shroud is printed in PETG, which is exactly the kind of material choice you want for an application like this.
3. It should install fast
According to the current CryptoCloaks product page, the shroud installs in under 5 minutes, mounts using two existing rear screws, and requires no drilling. That is the right way to do a home mining accessory: clean, reversible, and simple.
4. It should offer the duct size you actually need
The current CryptoCloaks version is offered in 6-inch and 8-inch. That is not cosmetic. Duct size affects routing, resistance, and how cleanly the setup fits your actual space.
6-inch vs 8-inch: which one should you buy?
Choose 6-inch if:
- your duct run is short
- your routing is simple
- you already have 6-inch ventilation parts
- you want a more compact residential setup
Choose 8-inch if:
- your run is longer
- you want lower resistance
- you are pairing it with a larger exhaust setup
- you want to move the same exhaust volume with less restriction
There is direct review evidence on the product page supporting this. One verified buyer wrote that the 6-inch shroud works well for a short exhaust line. Another reported pairing the shroud with an 8-inch exhaust fan.
Simple answer: if you are not sure, 6-inch is the safer default for a short, basic home install. If you are building around a longer run or care more about minimizing restriction, 8-inch is the stronger choice.
Do you need an inline fan?
Not always. It depends on the duct run, bends, outlet path, and how restrictive the overall setup is.
What is verified is that the shroud itself is a duct adapter for standard ducting, and verified buyers have paired it with both simple duct routing and fan-assisted setups.
The safe, accurate answer is this: for a short, clean duct run, the shroud and duct may be enough. For longer or more restrictive runs, airflow resistance matters more, and larger ducting or fan assistance can make more sense.
Fit and installation
People do not want theory here. They want to know whether it fits and whether install is annoying.
The current CryptoCloaks product page shows 16 verified reviews with a current aggregate rating of 5.00 out of 5. Multiple reviews explicitly mention fit and easy installation.
- “Easy to install and a perfect fit.”
- “Fits Avalon Q well!”
- “Fits like a glove.”
- “Works as advertised.”
According to the current product page, the shroud mounts using two existing rear screws, requires no drilling, and installs in under five minutes.
Why PETG matters
This is not the kind of part where the cheapest printable plastic wins.
The shroud sits on the hot exhaust side of a working ASIC. The current CryptoCloaks listing is explicit that the shroud is printed in PETG. That matters.
If a part is going to live on the exhaust side of a miner, material choice is not a throwaway detail. “3D printed” alone does not tell you much. PETG is the kind of material choice you want to see for a hot-air application like this.

Is PETG the right material for this?
For a hot-air application on the exhaust side of a miner, PETG is the kind of material choice you want to see. The current CryptoCloaks listing specifies PETG.
Do I need an inline fan?
Not always. For short, simple duct runs, you may not. For longer or more restrictive runs, larger ducting or fan assistance can make more sense.
