Dell server replacement fan

This 120 mm DC fan is built for Dell servers that require the 4715KL-04W-B86 model. It delivers 12 V operation at 2.50 A through a four-pin connector designed for temperature-controlled speed regulation. The double ball bearing supports a speed range from 1500 rpm up to 7800 rpm. Noise output spans 20 dB at low speed to 75 dB at maximum. Rated life is 50000 hours.

Check connector and clearance before ordering

Verify that your server chassis accepts a 12038 form-factor fan with a four-wire PWM interface keyed for Dell pinouts. Confirm the mounting hole pattern matches the 120 mm spacing used in the target Dell model. Ensure the system fan header can supply 12 V at 2.50 A without current limiting. No LED lighting is present, so the unit will not add visual indication.

Replaces worn or failed OEM Dell cooler

This unit directly substitutes the original NMB 4715KL-04W-B86 when bearings degrade or airflow drops below specification. The upgrade is worthwhile when the existing fan reaches end of life or runs at 75 dB under load. It is not suited for builds needing a heatsink assembly, liquid cooling integration, or standard consumer motherboard headers.

Questions about this item

Does the 4715KL-04W-B86 ship with mounting hardware or just the 120mm fan unit?

The product is listed as fan only, so only the 120mm 4-pin fan is included; any brackets or screws for a specific Dell server must be sourced separately.

Which speed range suits a quiet Dell server versus a high-airflow build using this 1500-7800 rpm fan?

At 1500 rpm the noise is near 20 dB for quiet operation; at 7800 rpm it reaches 75 dB for maximum airflow, so choose the lower end for silence and the upper end for cooling headroom.

What does the 2.50 A current draw mean for a Dell server 12 V 4-pin header?

The fan draws 2.50 A at 12 V, so the server's 4-pin temperature-control header must be rated for at least that current to run the fan at its full 7800 rpm speed.
