Compact 40 mm server fan
The Zyvpee 1611RL-04W-B86 B02 is a 40 x 28 mm case fan built for 12 V server environments. It targets administrators maintaining or repairing compatible rack units where a direct-replacement cooler is required.
0.75 A draw and ball bearing life
The unit pulls 0.75 A on a 4-pin connector, giving enough airflow for dense 1U power-supply bays. Headroom drops quickly if static pressure rises beyond the original chassis design, so it suits stock configurations rather than modified airflow paths.
Replaces LITEON PS-2751-2F cooler
This model matches the original fan used in the R520G7 platform, making the swap straightforward when the factory unit fails or grows noisy. The jump is worth it only when the existing 4028 frame size and 4-wire pinout must stay identical.

Questions about this item
Will this 40×28 mm ball-bearing fan fit the same mounting holes as my existing 40 mm cooler?
Yes, the 40 mm square frame matches standard 40 mm mounting spacing, so it aligns with the holes used by your current 40 mm fan.
How can I confirm the 4-pin PWM control is functioning after installation?
In BIOS or fan-control software the fan should appear as a PWM device; its speed will scale with the duty-cycle curve you set, proving the fourth wire is active.
Does the package include mounting screws or only the bare 1611RL-04W-B86 unit?
Only the fan itself is supplied; you will need four 40 mm case-fan screws or rubber mounts separately.
