Compact 40 mm fan for tight spaces

This 40 by 20 mm axial fan runs on 24 V at 0.14 A through a two-pin connector. It uses ball bearings and has no LED lighting, making it a straightforward replacement for small-form-factor or industrial chassis.

Suits 24 V systems with two-pin headers

Builders working on 24 V platforms that provide a simple two-pin header can drop this unit in directly. It does not suit systems that require PWM speed control or a different voltage supply.

24 V 0.14 A two-pin power requirement

The cooler draws 0.14 A at 24 V over a two-pin connection, so the host must deliver that exact voltage and connector type. Verify the header specification before purchasing.

Questions about this item

What comes in the box with the FD2440-S1142D and is a mounting kit included?

The package contains the 40 mm ball-bearing fan with its 2-pin 24 V 0.14 A lead; no screws, brackets or adapters are supplied, so you will need to source suitable 40 mm mounting hardware separately.

The title mentions 40*20 mm and 4020 — are these different versions or the same cooler?

They refer to the identical 40 mm square, 20 mm thick frame; 4020 and 40*20 mm are simply alternative ways of writing the same physical dimensions.

With a 24 V 0.14 A rating, what airflow or cooling performance can I expect once installed?

The electrical rating is 24 V at 0.14 A; actual airflow and temperature reduction will vary with case restriction, heatsink design and ambient conditions.
