High-airflow 120 mm server fan

The Zyvpee 4715KL-04W-B56 is a 120 mm by 38 mm case fan built for server chassis. It runs on 12 V DC at 1.3 A and uses a four-pin power connector for speed control. Dual ball bearings support a speed range of 3500 to 3999 RPM and deliver more than 80 CFM of airflow. The black frame carries no lighting.

Suited for dense server racks

This fan fits builds that need high static pressure in a 38 mm thick slot and can supply a four-pin header at 12 V. It is not for systems limited to thinner fan bays or for quiet desktop environments where lower RPM is preferred.

Deciding specification: 38 mm thickness

The 38 mm frame depth is the single dimension that determines whether the fan will mount in your chassis. Verify that your case or tray accepts this thickness before ordering.

Questions about this item

Will the 4-pin PWM connector on the 4715KL-04W-B56 let my older motherboard control its 3500-3999 RPM speed range?

Yes, the 4-pin connector provides PWM control so a compatible motherboard can regulate the fan across its full 3500-3999 RPM range.

How can I confirm the 4715KL-04W-B56 is delivering its rated >80 CFM airflow after installation?

Monitor fan speed in BIOS or software to verify it reaches 3500-3999 RPM, and check that case temperatures drop under load.

Does the 120x38mm 4715KL-04W-B56 ship with mounting screws, or must I source them separately?

The fan includes mounting screws for standard 120mm case positions; no extra hardware is required for typical installation.
