Canaan Q Exhaust Shroud: Duct Your Miner Like a Pro
Running a Canaan Avalon Q at home is powerful. It’s also loud and hot. The shroud solves both problems — it captures the exhaust air and lets you duct it out a window instead of into your living room. This guide walks you through why ducting matters, how to install it, and when to choose 6-inch vs 8-inch.
Why Duct Your Miner’s Exhaust?
The Canaan Q pulls 3,300W of power and converts nearly all of it to heat. Without ducting, that heat stays in your room. Your AC runs harder. Your electric bill climbs. The noise compounds because your AC kicks into overdrive.
With a shroud and duct, you’re solving three problems at once:
- Temperature control: Hot air exits the house, not your living room. Room stays 10-15°F cooler.
- Noise reduction: Ducting dampens the acoustic signature by 8-10 dB. Significant difference in a home setting.
- Electric cost: Less AC load = lower cooling costs. Breaks even in 2-3 months of mining.

- Duct adapter ring (6″ or 8″ bore)
- Installation guide with photos
What you provide:
- Flexible aluminum ducting: 6-inch options or 8-inch options, 25-50 feet recommended
- Window exit adapter or wall vent (depends on your setup)
- Zip ties or stainless-steel duct hose clamps

Installation time: 20-30 minutes, no special tools needed.
6-Inch vs 8-Inch Ductwork: Which Should You Choose?
The difference is airflow and noise. Larger ducts move air more freely, which means quieter operation and less backpressure on the miner’s fan.
| Spec | 6-Inch | 8-Inch |
|---|---|---|
| Airflow (CFM) | ~650 CFM | ~1,100 CFM |
| Noise Level | ~55 dB | ~48 dB |
| Cost (ductwork) | $30-50 | $45-80 |
| Installation Ease | Easy (more flexible) | Medium (stiffer, more rigid) |
| Best for | Tight spaces, basements | Primary noise/cooling priority |
Our recommendation: Start with 8-inch if you have the space. The noise reduction is worth it, and you’re only paying $15-30 more for ductwork. If your room is tight or you’re threading ducts through walls, 6-inch works fine.
Step-by-Step Installation
Step 1: Prepare the Miner
Power down the Canaan Q completely. Unplug it. Let it cool for 10 minutes — the exhaust area will be hot. Once cool, inspect the rear exhaust port for dust or debris. Wipe it clean with a dry cloth.
Step 2: Attach the Shroud
The shroud bolts directly to the exhaust port. Align the mounting holes and insert the bolts from the kit. Tighten firmly but not aggressively — you’re not stripping aluminum here. The shroud should sit flush against the rear of the miner.
Step 3: Connect the Duct Adapter
The duct adapter ring is integrated into the shroud. If you ordered 8-inch, the adapter is sized for 8-inch flex duct. Slide your flex duct over the adapter and secure with a hose clamp. Tighten the clamp until snug — the duct should not slide.
Step 4: Route the Duct
Plan your duct run. The shortest path wins — long ducts with many bends increase backpressure and noise. Ideal setup:
- Straight shot out a window (best)
- Through a wall vent
- Along a baseboard to an external exhaust port
Avoid sharp bends. If you must bend, use a 6-inch bend radius (flexible duct handles this). Support the duct every 4-6 feet with clips or ties to prevent sagging.
Step 5: Seal the Exit
Where the duct exits the house, use a window adapter or wall vent. These prevent hot air from backing up and moisture from entering. Standard hardware store vents work fine — aluminum or plastic, doesn’t matter. Seal any gaps with weather stripping or caulk.
Step 6: Power On and Listen
Turn the miner back on. Let it run for 5 minutes. Listen for any rattles or vibrations in the ductwork. The sound should be a steady, low hum with air moving. If you hear squealing, the duct adapter might be too tight on the flex duct — loosen the clamp slightly.
Maintenance and Longevity
The shroud and ductwork are passive systems — no moving parts, no filters, nothing to wear out. Annual maintenance is minimal.
- Every 3 months: Visually inspect the duct for any kinks or damage. Flex duct can degrade over years of sun exposure, so if your external duct is outside, consider shade or UV-protective wrap.
- Every 6 months: Check the shroud bolts to ensure they’re still tight. Vibration can loosen fasteners over time.
- Annually: Inspect the exterior vent for dust or blockage. Clear any debris.
The aluminum shroud will last as long as your miner. The flex duct typically lasts 5-7 years before UV degradation becomes noticeable.
Real-World Impact: Numbers
Let’s run the math. Assume a Canaan Q running in your home office, 12 hours/day, without ducting vs. with ducting.
Without ducting:
- Miner heat: 3,300W into the room
- Room temperature rise: +12°F over ambient
- AC runs harder to cool the room
- Added cooling cost (estimate): +$40-60/month
- Noise: 65 dB (constant, noticeable even with door closed)
With 8-inch ducting:
- Heat exits the house, room stays cool
- AC minimal extra load
- Added cooling cost: +$5-10/month (passive cooling loss)
- Noise: 48 dB (quiet enough for a home office)
Net savings: $30-50/month in cooling costs. The shroud + duct pays for itself in 1-2 months.
Noise Reduction in Practice
The Canaan Q at full throttle is loud — 65 dB is roughly equivalent to a garbage disposal or a busy restaurant. With the 8-inch shroud and duct, you drop to 48 dB, which is comparable to normal office background noise or a refrigerator. The difference is the miner becomes acceptable in a bedroom or office setting.
If you’re mining in a basement or garage, ducting is optional but still recommended for temperature control and electricity savings.
Where to Get Everything
Shroud and adapter: Canaan Q Exhaust Shroud (6″ or 8″) — CryptoCloaks
Flex duct: Use the supporting-supply links above or buy locally. You need 25-50 feet of aluminum or foil flex duct sized to your adapter (6″ or 8″ diameter).
Window/wall vent: Hardware store, $15-30. Standard dryer vent or flexible aluminum duct exit.
Hose clamps: Standard stainless-steel clamps, usually $2-5. Get 2-3 for your duct run.
Optional cooling upgrade: Pair your shroud with a Canaan Q stand for better airflow underneath the miner.
FAQ
Q: Can I use the shroud without ductwork?
A: Yes, but you lose the benefit. The shroud still cools the miner slightly, but heat stays in your room. Ducting is where the magic happens.
Q: Will the duct vibrate or rattle?
A: Flex duct naturally resonates at certain frequencies. If you hear buzzing, secure the duct more firmly to walls or use rubber isolation clamps where the duct attaches to the shroud.
Q: What if I can’t duct outside?
A: You’re stuck with room cooling loss. The shroud still helps by directing heat in a controlled manner, but it won’t exit the house. Consider a portable AC unit in your mining room if heat is a problem.
Q: How often do I need to replace the flex duct?
A: 5-7 years depending on sun exposure. Interior ductwork lasts longer. If you notice tears or significant degradation, replace it. Efficiency drops with duct damage.
Q: Does the shroud affect miner performance?
A: No. The shroud and duct are purely passive. Hashrate, efficiency, and power draw remain unchanged. You’re just managing the heat output better.
The Bottom Line
The Canaan Q is a serious piece of hardware — 3,300W of power, serious hashrate, serious heat. Ducting that heat out of your home is the simplest way to run it comfortably. You save on cooling costs, reduce noise, and keep your space livable. Installation is straightforward, cost is low, and the payback is fast.
If you’re running an Avalon Q at home, the shroud is not optional. It’s the one accessory that transforms the experience from “hot and loud” to “manageable and efficient.”
