127 mm 48 V Server Fan

The SXDOOL 5015KL-07W-B49 is a 127 mm square frame fan designed for 48 V DC server and inverter cooling. It draws 0.46 A and spins at 4000 RPM with a tolerance of ±10 %. The two-ball bearing supports continuous high-speed operation in industrial environments.

Three-Pin Power Limitation

The fan uses a three-pin power connector that supplies voltage without a dedicated PWM control wire. Speed is therefore managed by varying the supply voltage rather than a duty-cycle signal. Motherboards or fan controllers without voltage-regulation capability will run the fan at a fixed 48 V and maximum RPM.

Replaces Lower-Airflow 127 mm Units

This model delivers 180 CFM, well above the 80 CFM baseline for the size class, making it a direct upgrade for chassis that currently use quieter but weaker 127 mm fans. The jump is worth it when thermal headroom is exhausted and the 38 mm thickness fits the mounting points. Buyers who need speed reporting or PWM control should look elsewhere.

Questions about this item

Should I pick the 48 V model or a lower-voltage version for my server chassis?

This fan runs on 48 V DC at 0.46 A; choose it only if your power supply or backplane delivers 48 V.

What does the 180 CFM rating mean once the fan is installed in a real server?

At 4000 RPM it moves 180 CFM of air, giving strong throughput for dense 127 mm inverter or server cooling.

The fan uses a 3-pin connector — what does that cap in practice?

The 3-pin power connector supplies 48 V DC and tachometer feedback but does not support PWM speed control.
