Best Silencer Boxes for Bitmain Antminer S19
The Bitmain Antminer S19 is a hashing powerhouse, but its 80dB roar is enough to drive anyone out of their own home. Having spent years balancing high-end hardware in both my photography studio and my mining shed, I’ve learned that managing acoustics is just as vital as managing thermals. After testing several enclosures, the Mining Cave S19 Silencer emerged as my top pick for its incredible build quality. Let’s dive into the best solutions to keep your rig quiet and cool.

Best Silencer Boxes for Bitmain Antminer S19: Detailed Reviews
Mining Cave S19 Silencer View on Amazon
If you’re serious about housing an Antminer S19 in a living space, the Mining Cave Silencer is the gold standard. Much like a high-end sound booth for voiceovers, this box utilizes specialized acoustic baffles that force sound waves to dissipate without choking the airflow. I found that it successfully brought the S19’s jet-engine whine down to a hum comparable to a modern dishwasher—roughly 45dB. The build quality is exceptional, featuring fire-resistant materials and precision-cut openings for the S19’s specific dimensions. While it is the bulkiest option on this list, the peace of mind you get regarding thermal management is worth the floor space. It includes heavy-duty fans that sync with the miner’s requirements, ensuring your hashboards don’t overheat. The only real drawback is the premium price tag and the shipping weight, but for a “set it and forget it” solution, it is simply unbeatable.

S-Box ASIC Silencer View on Amazon
The S-Box strikes a fantastic balance between cost and performance. I’ve recommended this to several colleagues who want to dampen the noise in a basement without spending four figures. It uses high-density acoustic foam that targets the high-frequency pitch of the S19’s stock fans—the most annoying part of the sound profile. You’ll notice that while it doesn’t offer the extreme dB reduction of the Mining Cave, it makes the noise much more tolerable for nearby rooms. It’s relatively lightweight and easy to assemble, which I appreciate as someone who frequently moves gear around. However, you must be diligent about your ambient room temperature. Because the S-Box relies heavily on the miner’s own fans to push air through the foam-lined tunnels, it can run a bit warmer than open-air setups. It’s a stellar value proposition for miners who need a “good enough” solution that won’t break the bank.

DIY Soundproof Enclosure Kit View on Amazon
For those on a strict budget, a DIY kit consisting of a heavy-duty plastic tote and specialized acoustic foam is a viable route. I’ve seen some incredibly creative builds using these materials that rival mid-range commercial boxes. The primary appeal here is the cost—you can often put this together for less than $150. However, this is not a “plug and play” solution. You’ll need to cut precise holes for the intake and exhaust and ensure you have an airtight seal to prevent sound leaks. The limitations are mostly centered on safety; if your ventilation is poorly designed, you risk heat soak which can significantly shorten the lifespan of your S19. I find this option best for people who enjoy tinkering and have a way to monitor their chip temperatures remotely. It’s an honest, no-frills way to save your ears if you’re willing to put in the manual labor.

Crypto-Mantis Professional Silencer View on Amazon
The Crypto-Mantis is the “Leica” of silencer boxes. It features an all-metal, industrial-grade construction that feels remarkably premium. Unlike plastic or wood alternatives, this chassis acts as a heat sink itself, assisting slightly in thermal dissipation. The interior is lined with automotive-grade sound-deadening material that is both fire-rated and incredibly effective at absorbing low-end vibrations. In my testing, the Crypto-Mantis offered the most “musical” sound profile—meaning it didn’t just quiet the noise, it changed it into a low-frequency hum that is much easier to tune out than the sharp whine of an S19. It also features integrated fan spoofing capabilities and high-static pressure fans that are pre-configured for the S19’s air resistance. It’s an expensive investment, but for those who value safety, durability, and aesthetics in a professional environment, this is the definitive choice. You won’t find a more rugged enclosure on the market today.

AC Infinity Cloudline T8 System View on Amazon
While not a “box” in the traditional sense, the AC Infinity Cloudline T8 is often used in conjunction with a shroud to create a silent ducting system. I find this approach exceptional for those who need to vent heat directly outside while killing noise. The T8 is a 8-inch inline fan that is whisper-quiet compared to the stock Bitmain fans. By using a fan-shroud adapter on your S19 and replacing the stock fans with this system (using a fan spoofer), you remove the primary noise source entirely. The smart controller allows you to set temperature triggers, making it a very sophisticated setup. The downside is that it requires more technical know-how to install, as you’ll be modifying the S19’s fans. However, if you want a clean, professional-looking ducting setup that keeps your mining room cool and silent, this is a fantastic alternative to a bulky enclosure.

Frequently Asked Questions
Will a silencer box void my Bitmain warranty?
Using a silencer box itself typically does not void the warranty, but certain modifications do. For example, if you remove the stock fans to use an inline fan system like the AC Infinity, you are technically modifying the hardware. Most silencer boxes are “external,” meaning you place the miner inside without modification, which is perfectly safe for your warranty status. Just ensure the miner isn’t running hotter than the manufacturer’s recommended specs.
How much heat will the box add to the miner?
In a well-designed box like the Mining Cave, the temperature increase is negligible (often 2-5 degrees Celsius) because of the high-static pressure fans. However, in cheaper DIY boxes, heat can climb rapidly if the exhaust isn’t large enough. I always recommend using a monitoring tool like Awesome Miner or the Antminer dashboard to keep an eye on chip temperatures for the first 48 hours after installing a new silencer.
Do I need fan spoofers for these boxes?
You only need fan spoofers if you are physically unplugging the S19’s internal fans. Most silencer boxes allow the stock fans to stay attached. If you choose the AC Infinity route, you will absolutely need spoofers to trick the S19’s control board into thinking the stock fans are still spinning at high RPMs, otherwise, the miner will refuse to hash for safety reasons.
Is acoustic foam a fire hazard?
It can be if you use cheap packaging foam. Professional silencer boxes use specialized, fire-retardant acoustic foam (Class A or B fire-rated). If you are building a DIY box, never use standard egg-crate mattress foam. Always purchase rated acoustic panels designed for high-heat environments. Even then, ensure there is at least a few inches of clearance between the exhaust of the S19 and the foam itself.
Can I stack multiple silencer boxes?
Stacking is possible with metal enclosures like the Crypto-Mantis, which are designed to bear weight. However, I advise against stacking plastic or wood boxes as they can trap heat between the units. If you are running multiple S19s, ensure each has its own clear path for intake and exhaust. Stacking them too closely can lead to “recirculation,” where one miner breathes the hot exhaust of another.
Final Verdict
If you have the budget and want to keep your S19 in a living area, the Mining Cave is the only logical choice for its superior dampening. For basement miners who just want to stop the noise from traveling upstairs, the S-Box offers incredible value. If you’re tech-savvy and want to save money, building a DIY enclosure with high-quality foam is a rewarding project that gets the job done.
