SKU CH-BRCX-FY3DV

A 5 V, 0.18 A miniature case fan with three-wire control for compact cooling

  • Compact 2.5 cm frame fits tight chassis spaces
  • 5 V operation runs directly from motherboard headers
  • Three-wire design enables speed monitoring
  • Low 0.18 A draw minimises power load

Miniature 5 V case fan

The ASB02505HHA is a 2.5 cm three-wire fan that runs on 5 V and draws .18 A. Its compact frame is designed for tight spaces where a standard cooler cannot be installed. The unit delivers targeted airflow for component-level heat dissipation.

Builders needing focused spot cooling

This fan suits projects that require a tiny 5 V blower for chipset heatsinks, router enclosures or portable devices. Buyers who need higher static pressure, PWM speed control or a larger frame for case ventilation should look at other options.

Questions about this item

What mounting-hole spacing does the 2.5 cm frame require?

The 2.5 cm square frame uses the standard spacing for that size; measure the four corner holes on your chassis or heatsink to confirm alignment before ordering.

Which wire on the three-wire lead is the tach signal so I plug it in correctly?

The three-wire lead follows the usual colour code — red for 5 V, black for ground, and the third wire (typically yellow) carries the speed signal to the header.
