VF40281BX-D190-S9H: 40 x 40 x 28mm Axial Fan

Use the full VF40281BX-D190-S9H part number when comparing this fan with an existing component. The 28mm depth distinguishes it from thinner 40mm fans and must fit the available space.

Can I select a replacement just by frame size?

No. Compare the supply rating, connector, pin assignment and control requirements as well as the frame. A 40mm fan with a different depth or connection is not automatically interchangeable.

Is this suitable for a noise-sensitive installation?

Review the speed and acoustic information in the original specification below against your installation's requirements. Do not treat the small frame as evidence of quiet operation. Check the exact connector and control interface before ordering multiple units.
