Supermicro 40mm Counter-Rotating Fan for GPU series

Supermicro 40mm Counter-Rotating Fan — Powerful GPU Case Cooler

For users of 1U chassis with four GPUs, cooling is a key factor in ensuring optimal performance and long-term reliability. Specially designed for Supermicro's 1U 4-GPU chassis, this Sunon fan (model PF40561BX-Q40U-S9H) delivers maximum airflow of 34.8 CFM, which is essential for cooling components with high thermal loads. With rotating speeds of up to 23,300 RPM (inlet) and 20,300 RPM (outlet), it efficiently dissipates heat even in demanding conditions. It has undergone thorough testing and validation by Supermicro, ensuring high quality and reliable performance.

Exceptional Cooling Performance

With a compact size of 40 x 40 x 56 mm, this fan is ideal for use in space-constrained chassis without compromising cooling efficiency. The acoustic noise level of 69.4 dBA corresponds to the high-speed design that ensures optimal airflow even under maximum load. This fan is indispensable for maintaining stable performance of GPU systems in critical applications.

Reliability and compatibility

Thanks to the 4-pin connector, it is compatible with most motherboards designed for 1U chassis. The fan complies with RoHS and REACH standards, confirming its environmental friendliness. With rated current of 1.9 A, it is designed to be energy efficient while providing sufficient power for demanding cooling.
