Compact 40mm axial fan for 24V systems
The Zyvpee KF0420B2SR-R is a 40 by 40 by 20 millimetre case fan built for equipment that runs on a 24 volt DC supply. It draws 2.6 watts through a simple two wire lead and uses a ball bearing for consistent rotation in tight chassis spaces.
Ball bearing sustains steady airflow under
The ball bearing design maintains stable speed and acoustic profile during prolonged operation without the wear pattern that affects sleeve alternatives. Rated at 2.6 watts the motor delivers reliable torque for inverter or industrial cooling loops that run for extended periods without shutdown cycles.
Verify 24 volt header
Confirm that your board or controller provides a 24 volt DC header with two pin spacing that matches the supplied wires. The 40 by 40 millimetre footprint and 20 millimetre depth must fit the available mounting holes and surrounding component height in your enclosure.

Questions about this item
How much heat and noise does the 2.6 W KF0420B2SR-R produce when running 24/7?
The fan draws 2.6 W at 24 V and uses a ball bearing; expect a low but audible hum and minimal heat from the motor itself.
What power source must I already have to run this 24 V axial fan?
You need a 24 V DC supply capable of at least 2.6 W with a two-wire connection.
Will the 40 × 40 × 20 mm KF0420B2SR-R fit the same mounting holes as my older 4020 fans?
Yes — the 40 mm square frame and 20 mm thickness match the standard 4020 footprint.
