40 mm ball-bearing case fan

The Zyvpee 1606KL-04W-B40 is a 40 mm square case fan with a 10 mm thickness. It runs on 12 V DC power and uses a two-pin connector for simple polarity connection. The black frame houses a ball-bearing motor rated for CPU cooling duties. This non-LED unit suits compact builds or replacement cooling in tight spaces.

Replaces noisy or failed 40 mm fans

Swap this in when an existing 4015-size fan becomes loud, vibrates or stops spinning. The ball bearing handles continuous operation better than sleeve alternatives in similar footprints. The jump is worth it if the current fan runs hot or the bearing whine is audible. It matches the standard 40 mm mounting pattern for direct substitution.

Two-pin plug fits most headers

Installation requires aligning the two-pin connector with a matching header on the board or controller. Polarity must be observed so the fan spins in the correct direction. The 10 mm depth fits most 40 mm mounts but verify clearance against nearby components. A common issue is reversed wires causing the fan to run backwards or not start.

Questions about this item

Will the 40 mm by 10 mm frame fit a standard 40 mm fan mount?

Yes, the 40 mm square frame with 10 mm thickness matches the common 40 mm mounting pattern used on many small-form-factor cases and heatsinks.

How do I connect the 2-pin power lead to a 3-pin or 4-pin motherboard header?

Align the two pins with the outer two pins of the header — usually ground and 12 V — leaving the sense or PWM pin empty; the fan will run at full 12 V speed.

When should I expect the ball bearing to need replacement?

Ball bearings typically last several years of continuous 12 V operation; replace the fan when noise increases or airflow drops noticeably.
