Compact 40 mm DC fan for Cisco switches

This 40 x 40 x 20 mm fan runs on 5 V DC at 0.36 A and carries the NIDEC TA150DC B34658-55 designation. It is built for network equipment that requires a low-profile 4020 form factor and direct current power. The unit suits administrators maintaining compatible Cisco switches or similar rack gear.

Two-wire lead fits standard 5 V headers

Installation is a matter of aligning the 40 mm mounting holes and connecting the two-pin plug to a 5 V fan header. The main difficulty arises when the target device expects a three- or four-wire PWM signal or a different voltage, because this model supplies only a basic two-wire 5 V connection. Verify the switch pin-out before fitting.

Questions about this item

How can I verify the fan is spinning at the rated speed after installation?

The model TA150DC is specified at 150 (RPM reference) and 0.36 A at 5 V; measure current draw or RPM with a tachometer to confirm it matches those figures.

What connectors or mounting hardware are included with the 40×40×20 mm unit?

The fan ships as the bare 4020 frame with lead wires; no screws, adapters or Molex connectors are supplied, so provide your own M3 hardware and 5 V header.
