Zyvpee DFS3010SLS 30*10mm DC5V .6W 2-wire sleeve bearing mini case fan

Compact 30 mm cooling fan

The Zyvpee DFS3010SLS is a 30 mm square DC fan built for tight spaces such as small-form-factor CPU coolers. It runs on 5 V and draws only .6 W, making it suitable for low-power headers on compact boards. The two-wire sleeve-bearing design keeps the unit simple and affordable for basic airflow needs. Black, non-LED housing blends into any build without adding visual clutter.

Sustained airflow in confined layouts

At 10 mm thick the fan fits slim heatsink stacks where taller units cannot mount. Sleeve bearings run quietly at first but can develop a faint whine after extended continuous use, especially when oriented horizontally. The low .6 W draw means heat output stays minimal, so the fan itself does not add noticeable thermal load to the cooler. Expect steady, modest airflow rather than high static pressure for dense fin arrays.

Two-wire mounting and common pitfalls

Installation is straightforward: align the 30 mm screw holes and connect the two leads to a 5 V header or adapter. Polarity matters — reversing the wires will prevent the fan from spinning. The short lead length may require an extension in larger enclosures. Sleeve bearings are not serviceable; once noise appears the whole unit must be replaced.
