SKU CH-VXSQ-ZK0GH MPN PIA040H12PSize

A 40x40x28mm 12V case fan spins at 18000 RPM with double ball bearings, PWM control and 24.03 CFM airflow at 55.00dB

  • Double-ball bearings extend service life
  • 18000 RPM delivers 24.03 CFM airflow
  • PWM enables intelligent temperature-based speed control
  • 00 dB noise at full 12 V operation
  • 40x40x28 mm fits tight chassis spaces

Compact 40 mm PWM fan for tight spaces

This SXDOOL 40x40x28 mm case fan delivers 24.03 CFM at 18000 RPM using a 12 V, 0.81 A double ball bearing motor. It fits chassis heat dissipation, CPU radiator, power supply modification, water cooling assistance, and high-reliability server applications where a larger frame cannot be installed.

Suits builds that need high airflow in a 40 mm frame

Buyers who require lower acoustic output should note the 55.00 dB(A) noise rating at full speed. The 3-pin connector supports PWM speed control and RPM monitoring, so systems without a 4-pin header can still regulate the fan curve. It is not intended for silent-focused builds or installations that demand a larger mounting pattern.

18000 RPM double ball bearing determines lifespan

The high-precision double ball bearing is rated for 10.0000 hours of continuous operation and enables the 18000 RPM top speed that produces the stated airflow and pressure. This bearing choice and speed rating are the primary factors that decide whether the fan matches the thermal and acoustic targets of the specific installation.

Questions about this item

How long can the 18000 RPM fan run continuously before bearing wear becomes the limiting factor?

The double ball bearings are rated for 10.0000 hours of optimal continuous running time at full speed.

What noise and power levels should I expect when the fan runs at 18000 RPM all day?

At maximum speed it produces 55.00 dB(A) and draws 0.81 A at 12 V.

Does my motherboard need a 3-pin or 4-pin header to use the PWM speed control?

The fan uses a 3-wire 3-pin connector that supports PWM intelligent temperature and speed control.
