Phanteks M25-140 D-RGB Review

Phanteks M25-140 D-RGB is a 140 mm, 25 mm thick PWM case fan with 12 addressable D-RGB LEDs, daisy-chain support, a 500 RPM minimum speed and a 5 year warranty.

The M25-140 D-RGB is the 140 mm size of Phanteks' M25 lighting fan. It has 12 LEDs, a 4-pin PWM connector for speed control and daisy-chain support, so several fans can share one cable run. Speed can drop to 500 RPM, which helps for quiet idle behaviour, and power draw is 2.4 W. It weighs 195 g, is black, and has a 140 mm cable and a 5 year warranty. As a D-RGB fan, it needs a matching D-RGB header or controller, and it only fits mounts that accept 140 mm fans.

Scaling the M25

Phanteks keeps the M25's blade design and D-RGB ring consistent between the 120mm and 140mm versions, so mixed-size fan walls stay visually matched on the same hub.

Comparison to Alternatives

The Phanteks M25-120 D-RGB already in this catalog is the natural pairing for cases with mixed mount sizes; buy the 140mm version wherever the case supports it for slightly better airflow at a similar noise level. Against the Lian Li UNI FAN SL140 new to this catalog, the two compete closely on both performance and lighting quality, so the choice mostly comes down to which fan hub ecosystem the rest of the build already uses.
