Compact 40 mm case fan for targeted cooling

This Zyvpee 1604KL-04W-B50 is a 40 mm square case fan designed for CPU cooler compatibility. It runs on 12 V DC at 0.1 A and uses a ball bearing for durability. The black, non-LED frame measures 40 by 10 mm and suits small-form-factor builds or spot-cooling tasks.

Check connector and mounting before ordering

Verify that your motherboard or controller offers a 2 pin header for the 2 wire power connector. Confirm the mounting holes match a 40 mm fan pattern and that 10 mm thickness clears surrounding components. The fan draws 0.1 A at 12 V, so ensure the header can supply that current.

Replaces 40 mm sleeve-bearing or worn fans

This unit upgrades from older 40 mm fans that use sleeve bearings or have degraded airflow. The ball bearing and 12 V rating make the jump worthwhile when noise has increased or cooling performance has dropped. It is not for builders who need PWM speed control or larger fan frames.

Questions about this item

Does the 40 mm fan ship with mounting screws or do I need to buy them separately?

The unit is supplied as the fan only; mounting screws are not included and must be sourced separately.

Should I choose the 12 V 0.1 A 2-pin version or look for a different voltage?

This model runs on 12 V DC at 0.1 A with a 2-pin connector; select it only if your header matches those specs.

What does the 40 x 10 mm size mean for clearance inside a tight build?

At 40 mm square and 10 mm thick it fits narrow CPU cooler shrouds and small-form-factor cases where larger fans cannot.
