Fans 4006 5V .45W 4CM Ultra-thin DC Fan

SKU CH-KGXR-A9GH1

A 4 cm ultra-thin DC case fan running at 5 V and 0.45 W for tight-space cooling

  • Ultra-thin profile fits tight 4006 spaces
  • 5 V .45 W draw keeps power use low
  • 1000 model code identifies exact spec
  • Brand-new SUNON build ensures reliable operation
  • Compact DC design suits small chassis builds

Compact 4006 form factor

This 4006 ultra-thin DC fan is designed for tight chassis spaces where airflow must be added without increasing component height. It suits builders who need a low-profile cooling option for small form factor systems or dense component layouts. The 5 V supply makes it compatible with standard motherboard headers and controller hubs. Buyers who require higher static pressure for restrictive radiators should look elsewhere.

Low power draw at .45 W

Rated at .45 W, the fan draws minimal current from a 5 V header, keeping total system power impact negligible. The ultra-thin profile allows installation in slim enclosures where conventional thicker fans would interfere with adjacent hardware. Acoustic output remains modest during typical desktop workloads. Users who need PWM speed control or tachometer feedback will not find those features on this model.

Steady airflow at 1000 RPM

The motor spins at 1000 RPM to deliver consistent airflow during extended operation without thermal throttling. Bearing construction is intended for continuous duty in industrial and embedded environments as well as PC cases. Vibration stays low enough for noise-sensitive positions such as HTPC or office workstations. Applications demanding variable speed curves tied to temperature sensors are not supported by this fixed-speed design.

Questions about this item

How do I install the 4006 5V fan and what step is commonly missed?

Connect the 5V power lead to a compatible header and secure the 40 mm frame with four screws; the step often missed is verifying the 0.45 W draw does not exceed the header limit.

What maintenance or replacement will the 4006 fan need later?

Dust the blades periodically; if bearing noise appears after extended running, replace the unit as the motor is not serviceable.

What limit appears first on the 4006 fan under sustained use?

The 0.45 W power ceiling caps airflow, so the motor hits its thermal limit before the 5V supply becomes a constraint.
