ARCTIC P9 PWM PST CO 92mm Fan - Dual Ball Bearing
The ARCTIC P9 PWM PST CO is a 92 mm cooling fan designed for case, radiator and heatsink airflow where high static pressure is needed. It runs from 200 to 3000 rpm under PWM control, drops to silent operation in low-load conditions, and uses Japanese dual ball bearings for 24/7 reliability.
Why this product
0 dB silent idle mode
The fan stops completely below 5% PWM signal, eliminating noise when your system is under no load. It then ramps smoothly from 200 rpm upward as cooling demand rises.
High static pressure design
At 3.12 mmH₂O, it pushes air effectively through dense obstacles—radiator fins, heatsinks, filters—where ordinary fans lose thrust.
Daisy-chain speed sync
PST (PWM Sharing Technology) lets you connect up to four additional fans in series, all controlled by a single PWM signal for coordinated speed ramps.
Japanese dual ball bearings
Built for continuous 24/7 operation, the premium bearing design resists heat, dust and vibration without wear.
6-year warranty
Backed by ARCTIC's long-term durability testing and a full 6-year manufacturer guarantee.

- PWM fan headers on PC motherboards (4-pin connector).
- Case, radiator and heatsink cooling applications where static pressure matters.
- Multi-fan setups via PST daisy-chain connection (up to 5 fans on one PWM line).
- Requires 12 V DC supply; will not spin below 5% PWM threshold but reaches full 3000 rpm range above it.
Best for
- Silent passive cooling
- High-density radiator and filter cooling
- Synchronized multi-fan systems
- 24/7 continuous operation
Trade-offs
- Large open-case airflow where airflow volume matters more than pressure—the 38.83 cfm rating is moderate, suited to resistance rather than volume.
- Systems without PWM fan control—it requires a PWM-capable motherboard header.
The P9 PWM PST CO is a powerful 92 mm fan with 200 to 3000 rpm. The fan delivers a static pressure of 3.12 mmH2O and generates an airflow of up to 38.83 cfm. It offers precise control of the fan speed via pulse width modulation (PWM) and is extremely efficient at 0.12 A. In addition, it has a 0 dB mode for silent operation in IDLE. The P9 PWM PST CO delivers a focused airflow and guarantees a good airflow even with particularly high static pressure. Therefore, the P9 PWM PST CO is also specially suitable for use on heat sinks, radiators, pinholes and filters. The speed of the fan can be throttled down to a standstill via PWM. This allows silent operation in IDLE and at the same time guarantees maximum performance when required.
This enables the P9 PWM PST CO to be extremely flexible in adjusting the speed to optimally regulate the airflow for every case.
The P9 PWM PST CO is equipped with two japanese ball bearings. This makes these fans particularly durable and resistant to external forces such as heat, dust and vibrations. This variant is therefore the ideal choice for 24/7 operation. With a wide speed range and innovative PWM Sharing Technology (PST), the P9 PWM PST CO's fan speed can be controlled in sync with other fans. ARCTIC's PST fans come equipped with their own built-in daisy-chain solution, and, in addition to the plug-in connector, have another socket to which an additional fan or up to four other PST fans can be connected in series. To ensure the longevity of our products, we carry out long-term tests under different, sometimes very adverse conditions. In this way, we learn how we can permanently improve our products for our customers.
In addition, the excellent results of long-term testing give us the assurance that our products are not only outstanding in terms of quality, but also in terms of durability. This is a certainty that we are happy to pass on to our customers, which is why we give a 6-year manufacturer's guarantee.
