ASIC Miner Blower Silencer 2nd Gen | Low Noise Cooling Fan

Home mining gets loud fast, and the stock fans on most ASIC units are the main culprit. The 2nd Gen Blower Silencer takes that problem on directly. It pairs a brushless DC motor with a turbo fan and a stepless speed dial, so you can push airflow when your rig runs hot and ease off when you want some quiet. It sits at around 70 dB, moves up to 1100 m³ of air, and pulls anywhere from 70W to 300W depending on how hard you drive it.
The housing is heat-resistant engineering plastic, which keeps the 7 kg unit light enough to mount without extra bracing. Fitment is broad: Antminer S21, S19, T21, L9, KA3, KS5, D7 and L7, Whatsminer M60 through M20, most Avalon A series boards, and Iceriver KS3, KS5, AL1 and AL3. Set it up in minutes and get your workspace back.

Product Details :
1. Space-Saving & Portable Design
Built with a compact footprint, this blower silencer is easy to install, transport, and maintain. Its lightweight construction also helps lower shipping expenses and simplifies handling.
2. Continuously Adjustable Fan Speed
Featuring a stepless speed controller, the blower allows precise airflow adjustment to suit different operating conditions. This ensures effective cooling while improving energy efficiency and helping protect your ASIC miner from excessive heat.
3. Energy Efficient Brushless DC Motor
Equipped with an advanced brushless DC motor, the blower provides reliable airflow with lower power consumption and quieter operation compared to traditional AC motors. It supports both 50Hz and 60Hz electrical systems and can reduce energy usage by up to 50%.
4. Wide Miner Compatibility
Designed to fit a broad range of ASIC mining equipment using 120mm or 140mm cooling fans, making it compatible with leading brands such as Bitmain Antminer, Whatsminer, Avalon, and Iceeiver.
5. Fast & Simple Installation
The installation process requires only a few steps. Replace the original cooling fan, connect the included fan simulator, attach the blower, and your miner is ready for stable operation.
6. Low Noise Airflow System
Upgrade from noisy stock fans to a blower that produces smoother airflow with significantly lower sound levels, creating a quieter and more comfortable mining environment.
