40mm dual-motor case fan

This SXDOOL 40mm case fan uses a dual-motor design and 2-ball bearings to deliver high-speed airflow in a 40 by 40 by 56mm frame. It runs on a 12V supply and draws 1.75A, making it suitable for compact chassis or targeted component cooling where space is limited.

Build integration notes

The fan requires a 12V header or adapter capable of supplying 1.75A and a mounting area that accommodates its 56mm depth. Its small footprint frees up room around dense motherboard layouts or tight drive cages, but builders needing larger diameters or lower current draw should look elsewhere.

Highlights

  • Reliable 2-ball bearing for continuous operation

Questions about this item

How long will the 2 ball bearing last under continuous 12 V operation?

The dual ball bearing is rated for extended life at the specified 1.75 A current draw, reducing wear compared with sleeve alternatives.

What heat and noise level should I expect when the fan runs at full 1.75 A all day?

At 12 V and 1.75 A the dual motor moves a high volume of air through the 40 × 40 × 56 mm frame, so expect noticeable airflow noise and measurable exhaust heat.
