135 mm Dual Ball Bearing Fan

The SXDOOL RL4Z S1352512H is a 135 mm square case fan built with a dual ball bearing for long service life. It runs on 12 V and draws a rated current of 0.25 A with a maximum of 0.33 A. The frame measures 135 x 135 x 25 mm and the reference speed is 1700 rpm ±10 %.

Check mounting holes and power header

Verify that your chassis or power supply has the 120 mm parallel hole spacing or the 171 mm diagonal hole spacing used by this fan. Ensure the motherboard or fan controller provides a standard 2 pin header for the power connector. Confirm the 12 V supply can deliver the rated current for stable operation.

Suited for PSU and tight chassis cooling

This fan suits builders replacing a noisy power supply cooler or adding airflow to a compact enclosure that accepts the 135 mm footprint. It is not for systems that require PWM speed control or a 3 pin or 4 pin connector. Buyers needing higher static pressure or variable speed profiles should consider alternative models.
