Dell SFF Compatibility
This Foxconn blower fan is built for Dell OptiPlex 390, 790 and 990 small-form-factor desktops. It matches the original DP/N J50GH and 0J50GH part numbers used in those chassis. The 12 V, 0.75 A four-wire design plugs directly into the motherboard header. It restores factory cooling for systems that shipped with the PVB120G12H-P01 unit.
Ball Bearing Durability
The fan uses a ball bearing instead of a sleeve bearing, giving longer life under continuous server or desktop loads. Ball bearings resist dust ingress and maintain consistent speed over time. The non-LED housing keeps the focus on airflow without light distraction. Five blades move air through the blower duct efficiently.
Four-Wire PWM Control
A standard four-wire connector enables pulse-width-modulation speed control from the system BIOS or fan software. The motherboard can ramp the blower up under load and drop it to near-silent speeds at idle. No adapter cables or proprietary headers are required. The unit fits the existing screw pattern in the SFF cabinet.

Questions about this item
What does the 12V 0.75A rating mean for power draw in my system?
The fan runs at 12 volts and draws 0.75 amps, so it uses about 9 watts from the motherboard or fan-controller header.
How does the 4-wire PWM connector control the blower speed?
The fourth wire carries a PWM signal that lets the motherboard vary the blower speed precisely instead of just switching voltage levels.
Will this blower fit the mounting holes on a Dell OptiPlex 390 790 990 SFF chassis?
Yes, it is the original Foxconn DFB652512PN0T/PVB120G12H-P01 used in those Dell SFF models, so the screw pattern and shroud align directly.
