Fans KF0410B1HMAR 12V .8W 3-line mute case fan

SKU CH-FWN1-KAPHK

A 12 V case fan drawing .8 W with a 3-line connector for mute operation

  • Low power draw at just 0.8 watts
  • Runs on standard 12 volt supply
  • Three-wire connection enables speed control
  • Quiet operation for silent builds

Compact 12 V case fan for tight builds

This 5 cm frame fan draws 0.8 W from a standard 12 V header and uses a three-wire connection for speed reporting. The low power draw makes it suitable for small-form-factor chassis or auxiliary cooling spots where a larger fan will not fit. Buyers who need higher static pressure or greater airflow for dense radiators should look elsewhere.

Three-wire speed signal simplifies control

The third wire feeds a tachometer signal to the motherboard so fan curves can respond to actual RPM without extra controllers. No lighting, PWM header or mounting hardware is mentioned in the data, so builders who want addressable RGB or screw packs must source them separately.

Questions about this item

Will the 3-line connector on this fan need a different header later?

The 3-line connector fits standard 12 V fan headers; no adapter is required unless the board only offers 4-pin PWM headers.

What limits continuous running at 12 V and .8 W?

Sustained operation is limited by the motor's rated power draw and the bearing's design life at the specified voltage.
