140mm PWM case fan for radiators

The Phanteks M25-140 is a single 140mm by 25mm case fan built for high static pressure. It targets builders who need strong airflow through dense fin stacks such as radiators or heatsinks. The hydraulic bearing and wide PWM range suit both quiet daily use and demanding cooling loads. It connects via a standard 4-pin header and includes no lighting.

Thermals noise and power at typical speeds

At lower RPM settings the fan moves air through restrictive filters and radiators while keeping motor and bearing noise low. The supplier rates noise at 36.57 dB(A) and airflow at 104.62 CFM when the fan runs at its 1800 RPM maximum. PWM control allows precise adjustment between 500 and 1800 RPM so acoustic output matches the thermal demand. A single 4-pin connector powers the unit.

Sustained load behaviour and daisy-chain limit

Under continuous high-load operation the fan maintains its rated speed to deliver consistent cooling for powerful components. The hydraulic bearing is designed for durability during prolonged use at elevated RPM. Daisy-chain cabling lets multiple fans share one PWM signal, though each additional unit adds to the total current draw on that single header. Buyers who need more than one fan per header should verify their motherboard's current limit.

Perguntas sobre este artigo

How do I connect the 4-pin PWM daisy-chain cable to the motherboard header?

Plug the first fan's 4-pin connector into the CPU or chassis fan header, then link additional fans using the daisy-chain leads; the motherboard controls all fans from that single header.

How often should the hydraulic bearing be serviced or the fan replaced?

The sealed hydraulic bearing is maintenance-free; replace the fan only if noise rises above 36.57 dB(A) or airflow drops below 104.62 CFM after years of continuous use.

At what point does the 1800 RPM limit become the bottleneck during sustained loads?

When the curve hits 1800 RPM the fan cannot spin faster, so any extra heat must be handled by adding more fans or improving case airflow instead.
