40 mm High-Speed Case Fan

The Sunon PMD1204PQBX-A is a 40 mm case fan built for systems that need concentrated airflow in a small frame. It spins at 19000 RPM and delivers 23.4 CFM through a dual ball bearing. The 3-pin connector provides basic voltage control for standard motherboard headers.

Suitable For And Not For

This fan suits builders who need targeted cooling in tight chassis spaces such as 1U servers, compact workstations or GPU shroud replacements. It is not for users who prefer quiet operation, as the 59.9 dBA noise level is audible under load. Buyers needing larger airflow volumes or silent running should look at larger frame sizes.

Deciding Specification

The 19000 RPM speed is the single figure that determines fit. It drives the 23.4 CFM airflow and the 59.9 dBA output, so the buyer must decide whether that performance envelope matches the thermal and acoustic limits of their build.
