Phanteks SK123-140 D-RGB Review

Phanteks SK123-140 D-RGB is a 140 mm PWM case fan rated at 74.0 CFM, 1.9 mmH2O static pressure, 1500 RPM maximum and 29.7 dBA with a fluid dynamic bearing and D-RGB lighting.

The SK123-140 D-RGB is a 140 mm case fan with D-RGB lighting and a 4-pin PWM connector. It is rated at 74.0 CFM and 1.9 mmH2O at up to 1500 RPM and 29.7 dBA, and it uses a fluid dynamic bearing. That makes it a mainstream airflow fan for case intake or exhaust where lighting matters.

Comparison to Alternatives

Against the Phanteks M25-120 D-RGB already in our catalog, the SK123-140 pushes more raw airflow thanks to its larger 140mm frame, though at a lower static pressure. Compared with the Corsair AF140 Elite, the SK123 runs slightly louder at max speed but offers integrated D-RGB lighting the Elite lacks.
