Compatible Mining Hardware
This fan is a direct replacement for cooling fans used in a wide range of Bitmain Antminer models including the S7, S9, S9i, S11, L3+, A3, D3, T9+, and ElphaPex DG1/DG1+. It also fits other ASIC miners that use standard 120x38mm fans with a 4-pin PWM connector.
Why You Need This Fan
Cooling fan failure is one of the most common causes of miner downtime and hashboard damage. When a fan fails or degrades, temperatures spike, causing the miner to throttle performance or shut down entirely. Worse, prolonged overheating can permanently damage expensive hashboards and ASIC chips. Keeping spare fans on hand is essential preventive maintenance for any serious mining operation.
The SG121238BS uses high-precision dual ball bearings for reliable long-term operation, even under the continuous 24/7 demands of mining. The PWM speed control allows the miner firmware to automatically adjust fan speed based on temperature, balancing cooling performance with noise levels.
