A 12 V ball-bearing blower with a 4-pin connector draws 6.84 W for server CPU cooling
The SUNON PFC0251BX-C010-S99 is a DC blower fan built for server environments. It runs on 12 V power and draws 6.84 W through a standard 4-pin connector. Ball bearings support continuous operation in rack-mounted chassis. The black frame fits typical server airflow paths.
Technicians replacing a failed blower in 1U or blade servers will match the 4-wire PWM interface and voltage. Builders needing a large heatsink tower or quiet desktop cooling should look elsewhere; this unit is a bare blower without mounting hardware for consumer sockets.
The 4-pin connector supplies tachometer feedback and PWM speed control to the motherboard header. If the target system uses a 3-pin voltage-controlled header only, the fan will run at full speed without regulation. Verify the board provides 4-pin PWM before ordering.

The ball-bearing design reduces wear, so the fan typically runs for years without service. Periodic dust removal with compressed air keeps airflow steady.
The 6.84 W power draw at 12 V is the primary constraint; sustained loads that push the motor past this rating will trigger thermal protection first.
At 6.84 W the blower generates modest heat and a low, steady airflow sound typical of server-grade ball-bearing fans.
