ASIC Miner Blower Silencer Kit GEN 2
Blower Silencer 2nd Gen for ASIC Miners
The Blower Silencer 2nd Gen is an upgraded noise-management and airflow solution designed for ASIC miners, including Antminer, Whatsminer, Avalon, and Iceriver models. Built with a compact engineering-plastic shell, high-power brushless DC motor, internal turbo fan, and stepless speed controller, it helps reduce harsh miner fan noise while maintaining strong airflow for stable cooling.
Key Features
- Durable engineering-plastic shell: compact, lightweight, high-temperature resistant, and suitable for continuous mining environments.
- High-power brushless DC motor: lower operating power, smaller size, wider speed range, and reduced operating noise compared with traditional AC blower designs.
- Energy-saving operation: brushless DC motor design can reduce power usage while maintaining airflow performance.
- Internal turbo fan structure: provides strong air movement while helping soften the sharp, high-frequency sound produced by standard ASIC miner fans.
- Stepless speed controller: large control knob allows smooth airflow adjustment based on miner temperature and ambient conditions.
- Wide frequency compatibility: brushless DC motor design is suitable for 50 Hz and 60 Hz power environments.
- Noise management: helps reduce loud, harsh miner fan noise and produces a smoother, lower-frequency sound profile.
- Improved cooling support: designed to maintain stable airflow and may reduce miner operating temperature, depending on environment and installation.
- Easy installation: remove the original miner fans, install the fan speed simulators, fit the model-specific shroud, and connect the blower.

Advantages
- More compact than traditional silencer boxes.
- Helps reduce sharp ASIC miner fan noise.
- Maintains strong airflow for miner cooling.
- Stepless airflow adjustment for different mining environments.
- Energy-saving brushless DC motor design.
- Suitable for 50 Hz and 60 Hz power environments.
- Easy to install with model-specific shroud and fan simulator setup.
Important Notes
- Noise levels depend on miner model, room layout, ambient temperature, ducting, and installation method.
- A fan speed simulator is required for proper miner operation when replacing the original fans.
- Cooling performance depends on the miner model, airflow path, ambient temperature, and installation quality.
- Ensure the selected blower and shroud option matches the miner model and fan connector type.
Installation Instructions
- Power down your ASIC miner and disconnect it from mains electricity.
- Remove the original cooling fans from the miner.
- Install the provided fan speed simulator in place of the removed fans so the miner recognizes normal fan operation.
- Fit the model-specific blower shroud to the miner.
- Position the Blower Silencer 2nd Gen securely.
- Connect the blower to a suitable 220 V power source.
- Use the speed control knob to adjust airflow to the required level.
- Check that airflow is moving correctly through the outlet.
- Power the miner back on and monitor temperature, hashrate, and stability.
Installation typically takes around 5–10 minutes, depending on miner model and setup.
