Zyvpee PMD1238PKB2-A 40×20 mm 12 V 0.21 A 2.5 W 40 dBA 13000 RPM 2-wire case fan

Compact 40 × 20 mm case fan

The Zyvpee PMD1238PKB2-A is a 12 V DC fan measuring 40 by 20 mm with a 38 mm mounting pattern. It draws 0.21 A for 2.5 W and spins at 13000 RPM using a ball bearing. The two-wire connector provides power without speed reporting or PWM control.

Suits tight 40 mm mounts needing high airflow

Builders fitting a 40 mm CPU cooler, GPU shroud or small-form-factor chassis can use this fan where space is limited. The 40 dBA rating at full speed makes it less appropriate for silence-focused systems or noise-sensitive environments. Buyers needing PWM speed regulation or a three- or four-pin header should look elsewhere.

13000 RPM speed defines cooling capability

The fixed 13000 RPM determines the peak airflow and static pressure this fan can deliver. At 2.5 W it moves more air than slower 40 mm alternatives but generates 40 dBA doing so. Match this speed to your thermal target before purchasing.
