Replacement fan for Dell Optiplex SFF
This 4-pin radiator fan is a new original spare part built for Dell Optiplex 3050, 5050 and 7050 small-form-factor desktops. It matches the manufacturer part number 7D86K and the AVC model BAZB0925R2U. The unit suits owners or technicians who need a direct drop-in replacement for a worn or noisy cooler in these specific chassis.
Installation notes and common issues
The fan connects via a standard 4-wire PWM header and runs on 12 V DC at 1.0 A, so it fits the existing motherboard connector without adapters. Because the SFF layout is tight, the radiator must be removed from the case before the fan can be swapped; forcing it in place often cracks the plastic shroud. Reusing the original mounting screws avoids thread mismatch, and the cable should be routed clear of the side-panel latch.
Limits of the 4-pin PWM interface
The 4-pin connector allows the motherboard to vary speed through pulse-width modulation, but the firmware on these Optiplex models caps the maximum duty cycle, so the fan cannot exceed its rated 24 CFM even under heavy load. The control loop also lacks a user-accessible curve editor, meaning acoustic behaviour is fixed by the BIOS. Builders who want higher airflow or manual speed profiles will find the interface restrictive.
