Sunon PSD1206PMBX-A 6038 60x60x38mm 12V Double Ball Bearing Cooling Fan, High Speed PWM 4Pin Fan Replacement for Antminer S7 S9 Shenma M3 Miner Power Supply Heat Dissipation

This is a high-performance industrial cooling fan with official Sunon model PSD1206PMBX-A, dimensioned 60mm × 60mm × 38mm, specially customized as an aftermarket replacement cooling solution for cryptocurrency mining rig power units, widely compatible with Bitmain Antminer S7, S9 series miners and Shenma M3 mining equipment power supply modules.

Running on DC 12V rated voltage with 1.5A input current and 18W rated power, this fan delivers massive airflow and strong wind pressure at high rotational speed, rapidly expels accumulated high-temperature hot air sealed inside the mining machine power supply shell. It effectively solves common faults caused by poor heat dissipation, including power overheating protection, automatic shutdown, hash rate drop, component burnout and shortened power adapter lifespan during 24/7 non-stop mining operation.

Adopting premium double ball bearing internal mechanism instead of sleeve bearing, the fan greatly reduces friction loss and wear during long-term continuous running, boasting a rated lifespan of 50,000 working hours, stable operation with low vibration and durable anti-failure performance even in dusty, high-temperature mining farm environments.

Equipped with a 4-wire 4Pin motherboard interface, it supports real-time fan speed feedback detection and PWM intelligent temperature speed regulation. The mining machine mainboard can automatically adjust fan rotation speed according to internal temperature: running at low speed for quiet operation under light load, and boosting to full speed for maximum cooling under heavy load, balancing cooling efficiency and noise control perfectly. For simple direct power connection, you only need to connect the positive and negative two core wires for basic startup.

The rugged reinforced black plastic frame features anti-cracking, compression-resistant and dust-proof properties, with precision screw mounting holes for seamless installation on the original fan bracket of S7, S9 and Shenma M3 power supplies without any drilling or modification. Strictly tested for balance, wind volume and stability before delivery, it is a cost-effective and reliable spare cooling part for miner maintenance, power supply repair and mining farm equipment overhaul, greatly improving the overall running stability and safety of your entire mining system.
