ARCTIC F12 PWM PST 120mm Case Fan - PWM, 230-1350 RPM
The ARCTIC F12 PWM PST 120mm Case Fan is a PWM-controlled case fan designed for builders who want coordinated, efficient cooling across multiple fans. Its Fluid Dynamic Bearing and optimised blade design balance airflow with a low noise level, while PST (PWM Sharing Technology) lets all fans respond to a single control signal.
Why this product
PWM Sharing Technology synchronises fans
PST allows multiple fans to listen to one PWM signal—typically from your CPU cooler—so they spin down at low load and accelerate together when cooling is needed.
Fluid Dynamic Bearing for durability
The sealed oil capsule prevents lubricant leakage, delivering the quiet operation of a sleeve bearing with a much longer lifespan.
PWM control for precise regulation
The motherboard adjusts fan speed in real time to match cooling demand, maintaining the required temperature while keeping noise minimal.
Low noise at full speed
Even at maximum RPM, it produces only 0.3 Sone—comparable to ambient conversation in a quiet room.
- Size120 mm
- Speed range230–1350 RPM
- Airflow53 CFM (90.1 m³/h)
- Noise level0.3 Sone @ 1350 RPM
- Connector4-pin PWM
- ColourBlack
- SKUARC-3550
- EAN4895213702966
- Fits any 120 mm case fan mounting point (standard on most modern PC cases).
- 4-pin PWM connector works with any motherboard that supports PWM fan control.
- PST (PWM Sharing Technology) allows daisy-chaining multiple fans to a single PWM header without a splitter.
- Requires a PWM-capable motherboard header; it will not function on a standard 3-pin voltage-regulated connection.
Best for
- Multi-fan setups where coordinated speed control matters
- Quiet-focused builds; the 0.3 Sone rating keeps noise low even under sustained load
- Long-term reliability; Fluid Dynamic Bearing is rated for extended service life under varied conditions
- Builders who want motherboard-driven thermal management without manual adjustment
Trade-offs
- Systems with only 3-pin fan headers; PWM requires a 4-pin connection.
- High-pressure cooling scenarios; static pressure of 1.00 mmH₂O is modest for dense radiators or constrained cases.
- Extreme silence on a budget; the 0.3 Sone floor is already very quiet, but aftermarket ultra-low-noise fans may go lower at the cost of airflow.
The innovative design of the fan blades improves the airflow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimising the noise level yet delivering the desired airflow and pressure.
The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage. Thus this bearing is as quiet as a sleeve bearing but comes with a significantly higher service life.
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 to 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 durability.
If you want to improve the cooling efficiency of your computer you get several case fans working in parallel (since it takes 10 fans to double the noise level). But what does it help if they don't work together? The PST assures that all of your fans listen to one control signal. E.g. you share the CPU Cooler's PWM signal and assure that your case fans stand down at low load and spin up whenever necessary.
The PWM function allows the motherboard to run the fan precisely at its necessary speed. This guarantees the required cooling and minimises the noise level.
