Replacement 12 V chassis fan

The Vszerda RDH1225S is a 120 x 120 x 25 mm brushless DC fan that runs on 12 V at 0.40 A. It spins at 5500 RPM and connects with a 2-pin power lead. The unit is sold new and intended for swapping out a worn or noisy chassis cooler.

Best for direct 12 V two-pin headers

This fan suits builds that power cooling directly from a 12 V two-pin header without speed signalling. It will not work for systems that need PWM control, tachometer feedback or a three-pin or four-pin connector. Buyers who need variable-speed operation or a different mounting pattern should look elsewhere.

120 x 120 x 25 mm two-pin mount

The decisive specification is the 120 x 120 x 25 mm frame with a 2-pin power connector. If the chassis or heatsink uses that exact footprint and a two-pin header, the RDH1225S fits; otherwise it cannot be installed.

Questions about this item

Does the RDH1225S ship with mounting screws or do I need to supply my own?

Only the fan itself is included; standard 120 mm case screws must be purchased separately if your chassis does not already have them.

The listing shows a single 12 V 0.40 A version — is there any reason to look for a different voltage or speed?

This model is fixed at 12 V, 0.40 A and 5500 RPM; no alternative voltage or speed variants exist for the RDH1225S.

What does 5500 RPM actually deliver in a typical 120 mm case slot?

At 5500 RPM the fan moves a high volume of air through a standard 120 mm opening, making it suitable for CPU heatsinks or chassis exhaust where strong airflow is needed.
