Compact blower fan

The Fans BM4515-04W-B46 is a blower-style case fan built for directed airflow in tight chassis. It suits system builders who need focused cooling on a specific component or heatsink.

Builders with restricted clearance

This fan suits compact workstations or industrial enclosures where a radial design can push air through dense fin stacks. It is less suited for users who prefer quiet, high-volume axial airflow across an open case interior.

Targeted cooling capacity

The blower wheel delivers concentrated static pressure for heatsinks or restricted ducts. It runs out of steam when the build demands broad case-wide circulation or low-noise operation across large mesh panels.

Questions about this item

What power connector does the BM4515-04W-B46 blower need from my power supply?

The blower uses a 4-pin power connector, so your power supply must provide a matching 4-pin header or an adapter.

Can the BM4515-04W-B46 run alongside older 3-pin case fans on the same motherboard header?

Yes, the 4-pin blower will operate at full speed on a 3-pin header, while PWM control is only available on a 4-pin header.

How can I verify the BM4515-04W-B46 is spinning correctly after installation?

Check the fan speed reading in BIOS or monitoring software; a stable RPM value confirms the blower is powered and rotating.
