120 mm brushless chassis fan

The Vszerda RDH1225S is a 120 x 120 x 25 mm brushless DC fan designed for chassis cooling. It runs on 12 V and draws 0.40 A, spinning at 5500 RPM. The two-pin connector supplies power without speed reporting.

Replacement cooling for standard mounts

This fan suits builders replacing a failed 120 mm unit in a case, CPU cooler or other 12 V two-pin header. It does not suit systems that require PWM control, tachometer feedback or a different voltage.

5500 RPM fixed speed

The single specification that decides fit is the fixed 5500 RPM speed on a two-pin connector. Buyers needing variable speed or lower noise should look at PWM models instead.
