Compact 40 mm CPU cooler fan

The Zyvpee 1611KL-04W-B29 is a 40 by 28 millimetre axial fan designed for CPU cooler compatibility. It operates on 12 volt DC power and draws 0.11 ampere through a three pin connector. The black non LED housing uses a ball bearing for rotation. This unit suits builders replacing a same size cooler fan or fitting tight spaces where a 40 millimetre frame is required.

Ball bearing thermals and low current draw

Ball bearing construction provides consistent airflow with reduced friction over sleeve alternatives. The 0.11 ampere rating at 12 volts indicates modest power consumption for a fan of this class. Three pin wiring allows voltage based speed control from a motherboard header. Noise and thermal output remain proportional to the voltage applied in normal operation.

Direct replacement for 4028 form factor coolers

This fan matches the 4028 footprint and three pin interface found on many compact CPU coolers. It upgrades worn or noisy units of identical dimensions and pinout without modification. The jump is worth it when the original bearing has failed or acoustic levels have risen beyond tolerance. Buyers needing larger frames, PWM control or LED lighting should look elsewhere.

Questions about this item

How do I install the 40 mm × 28 mm fan with its 3-pin connector?

Align the four mounting holes of the 40 mm frame with the CPU cooler bracket, secure with screws, then press the 3-pin plug onto the motherboard or cooler header — the keyed notch prevents reverse insertion.

What maintenance will the ball-bearing fan need over time?

The ball bearing is sealed; no lubrication is required. Clean dust from the blades and frame with compressed air every few months to maintain airflow.

At what point does the 12 V 0.11 A limit constrain sustained cooling?

The fan draws a fixed 0.11 A at 12 V, so its maximum speed and airflow are capped by that power envelope — sustained loads cannot push it beyond the rated current.
