Three-fan pack for filtered chassis

The Phanteks M25-120 three-pack delivers three 120mm by 25mm case fans with hydraulic bearings and PWM control. Each unit spins between 500 and 2000 RPM, pushing 84.26 CFM at a listed 35.7 dB(A). The fans are designed for high static pressure across fine mesh filters, heatsinks and radiators, and include daisy-chain cables for tidy single-header wiring.

Replaces single-header multi-fan setups

Builders who currently run several fans from splitters or separate headers can consolidate to one PWM signal using the supplied daisy-chain leads. The jump is worthwhile when cable routing space is tight and the motherboard offers limited 4-pin headers, because the chain reduces clutter without sacrificing individual speed control across the trio.

Sustained load behaviour

At continuous 2000 RPM the fans maintain their rated airflow to keep demanding components cool, while the hydraulic bearing and high airflow-to-RPM ratio limit motor and bearing noise over long sessions. The wide 500 RPM floor also allows near-silent idling when thermal headroom returns, so acoustic output scales with actual cooling demand rather than staying fixed.

Questions about this item

Will three 120mm by 25mm fans fit my case fan mounts?

Each fan measures 120mm square and 25mm thick, so verify your chassis has three 120mm mounting positions with at least 25mm clearance per slot.

How do I connect the three fans using the daisy-chain cables?

Plug the first fan's 4-pin PWM connector into the motherboard header, then link the second and third fans in series using the supplied daisy-chain cables; a common mistake is forgetting to seat each connector fully, which breaks the PWM signal chain.

When should I expect to replace the hydraulic bearings?

Hydraulic bearings typically run for years, but if noise rises above the rated 35.7 dB(A) or RPM drops below the 500-2000 range, plan to swap the affected fan.
