Brand new original cooling fan from FOXCONN, model PVA092G12M-P14-05, DC12V 0.55A, 92×92×25mm with 4-pin PWM speed control connector. It features balanced airflow and static pressure, low vibration and moderate noise output. The anti-aging durable bearing enables stable 24/7 long-term continuous operation, widely applied in thermal management for servers, industrial controllers and power supply units. It is an ideal replacement for original fans with abnormal noise, bearing wear, stuck rotation or degraded cooling efficiency. Fan speed can be automatically adjusted by mainboard according to temperature, efficiently dissipating internal accumulated heat and fixing issues including overheating alarm, thermal throttling, system stuttering and unexpected reboot or shutdown. Important Compatibility & Wiring Notice Multiple OEM wiring variants exist for this model. Pinout sequence for power, ground, speed signal and PWM control line may differ between versions. Direct plug-in swap is not allowed, which may lead to fan failure to rotate, abnormal speed reading or driver circuit burnout. Please carefully match wiring order with your original fan before installation. You may send front & back photos of your old fan for compatibility check to prevent hardware damage induced by incorrect wiring.
