Compact 40mm Cooling Fan

The SXDOOL 1604KL-04W-B59 is a 40mm case fan designed for tight spaces in PCs or small-form-factor builds. It runs on 12V power and draws 0.1A through a standard 3-pin connector. The black, non-LED frame suits systems where subtle airflow is preferred over lighting.

Double Ball Bearing with Silent IC

The fan uses a double ball bearing paired with a specially designed silent IC to reduce motor noise. This construction targets a long working life rated at 180,000 hours MTTF. The bearing choice aims to maintain consistent speed and lower acoustic output over extended use.

Fixed Speed and Short Lead

Operating between 5500 and 5999 RPM, the fan delivers 6.0 CFM at 26 dBA within stated tolerances. The 3-pin connector provides power and tachometer feedback but no PWM control, so speed varies only with voltage changes. A 20 cm cable length limits placement to nearby headers or requires an extension for larger cases.

Questions sur cet article

How long will the double ball bearing last before it needs replacement?

The manufacturer rates the bearing at 180,000 hours MTTF, so under continuous operation it should run for many years before wear requires a swap.

What limits airflow when the fan runs at full speed for long periods?

The 6.0 CFM maximum air volume at 5500-5999 RPM is the hard ceiling; sustained loads cannot push more air through the 40 mm frame.

How much noise and heat does the fan produce during all-day use?

Noise stays between 25 and 30 dBA while drawing only 0.1 A at 12 V, so heat output remains minimal even after hours of continuous running.
