Compact 50 mm case fan

The Zyvpee D50SM-12C is a 50 mm square frame fan designed for tight case clearances. It runs on a 12 V DC supply and draws .21 A through a two-wire power connector. The black, non-LED housing suits builders who prefer a neutral look without lighting.

Thermals noise and power

At speeds between 2500 and 2999 RPM the fan produces a noise level of 20 to 25 dBA. The low current draw of .21 A keeps power consumption minimal in normal operation. DC square cooler construction provides steady airflow for confined spaces.

Sustained load behaviour

The two-wire design runs at a fixed voltage so speed remains constant during extended use. Noise output stays within the 20 to 25 dBA range without ramping. Continuous 12 V operation is supported by the DC motor for reliable long-term cooling.

Questions about this item

How do I install this 50×20 mm fan and which step is often missed?

Mount the 50 mm square frame with four screws, connect the two-wire 12 V lead to a motherboard header or fan controller, and verify the 0.21 A draw does not exceed the header limit.

What maintenance will this 2500-2999 RPM fan need later?

The sleeve bearing runs at 20-25 dBA; when noise rises or speed drops, replace the entire 50 mm unit as bearings are not serviceable.

What limit appears first during continuous 12 V operation?

The 0.21 A current ceiling and 2500-2999 RPM range cap airflow; sustained load hits thermal equilibrium at 20-25 dBA before any higher speed is possible.
