ARCTIC P12 Slim PWM PST 120mm Low-Profile PWM Fan
The ARCTIC P12 Slim PWM PST is a 120 mm low-profile fan designed for small form factor builds and space-constrained cooling applications. At only 15 mm thick, it fits where standard 25 mm fans cannot, yet delivers high static pressure and quiet operation through ARCTIC's custom motor design and fluid dynamic bearing.
Why this product
Fits where standard fans don't
At 15 mm deep, this fan installs in cases and radiators too shallow for conventional 120 mm fans. Mounting screws for radiator installation are included.
High static pressure in a thin profile
The optimised blade design generates 1.33 mmH₂O static pressure despite the compact form, making it effective on radiators, dust filters and restricted intakes.
Barely audible even at low speed
The newly-developed ARCTIC motor generates minimal vibration and commutation noise, with a maximum noise level of 22.5 dB, so you notice it least when you need it most.
Daisy-chain control via PST
PWM Sharing Technology lets you sync multiple fans through a single connector using the built-in socket—no additional hub required.
Spins down to silent standby
PWM control can throttle it all the way to 0 rpm below 9 % PWM, allowing the system to run silently when cooling demand is low.

- 4-pin PWM motherboard headers and PWM fan hubs that support standard PWM control.
- Radiators and water-cooling loops with standard 120 mm mounting holes, including push and pull configurations.
- Case intakes and exhausts where a 15 mm depth fits but a 25 mm standard fan does not—particularly small form factor cases.
- Operates in ambient temperatures from 0 °C to 40 °C, typical for indoor PC environments.
- Multiple fans can be daisy-chained together via the PST socket, but they will all spin at the same speed controlled by a single PWM signal.
Best for
- Small form factor and ITX builds where standard fan depth would not fit
- Radiator cooling when space behind the radiator is severely limited
- Dust-filtered or restricted intakes where high static pressure matters more than raw airflow
- Builders who prioritise quiet operation at idle and low loads
- Multi-fan setups that benefit from daisy-chain PWM control without an additional hub
Trade-offs
- High-volume airflow cooling: at 58.62 m³/h, this fan delivers less total airflow than a standard 25 mm 120 mm fan, so it is not suited for cases requiring maximum throughput cooling.
- Unrestricted case intakes: the high static pressure design optimises for resistance; in open intake scenarios a standard fan would move more air.
- Extreme overclocking: while capable and quiet, the 1.44 W power consumption and 2100 rpm ceiling are modest compared to high-performance alternatives.
Unlike standard 120 mm case fans with a thickness of 25 mm, the P12 Slim PWM PST has a mounting depth of only 15 mm. This makes it the ideal choice for Small Form Factor (SFF) builds. Corresponding screws for mounting on a radiator are already included.
Because the fan design of the P12 Slim PWM PST is optimised for focused airflow, it generates high static pressure. The fan enables extremely efficient cooling and good airflow — even with increased air resistance. This makes the P12 Slim PWM PST particularly well-suited for use on concealed case intakes, dust filters, radiators, and generally in small cases that have little space for free airflow due to compactly placed hardware.
The operating noise of the newly-developed ARCTIC motor is barely perceptible, even at the lowest speed. Thanks to its special magnetization, the motor of the P-fans generates no start-up jerks and only a fraction of the commutation vibrations of a conventional DC motor. As a result, there is far less vibration on the housing at different speeds and no need for rubber buffering or additional decoupling. The new ARCTIC motor generates significantly less frictional heat than its predecessors and current competitor models.
With a wide speed range and innovative PWM Sharing Technology (PST), the P12 Slim PWM PST'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.
Thanks to a combination of alloy and lubricant developed in Germany, friction within the bearing is minimized and greater efficiency is achieved. In addition to preventing lubricant loss, wear on the pin and sleeve is also reduced to a minimum. Less heat is developed, less bearing noise is generated and the life of the fan is extended significantly.
The speed of the P12 Slim PWM PST can be throttled down to a standstill via PWM. This allows efficient and silent PC operation in idle while guaranteeing maximum performance on demand.
The P12 Slim PWM PST allows customisable installation in the case. It can both suck in cool air as an Intake fan and push out warm air as an Exhaust fan. The fan also offers both push and pull installation options on the radiator.
