GFB0412EHSD is a highspeed 40x40x56mm server cooling fan crosscompatible with part number 32030159003. Powered by DC12V with 1.82A current rating, this 40mm fan delivers strong airflow and high static pressure to dissipate heat generated by CPU, memory and power modules inside compact 1U rackmount servers.
The 4pin interface provides PWM speed control and tachometer signal output, allowing the server mainboard to read fan status and adjust rotational speed dynamically according to internal temperature. Engineered for roundtheclock datacenter operation, it maintains reliable performance under heavyload conditions. This fan works as an ideal substitute when original unit triggers fan fault alarms, produces abnormal rattling noise or loses cooling capacity. Please confirm fan model, dimension, voltage and pin definition before ordering to ensure correct compatibility.
