Overview

ARCTIC, a German cooling specialist, has earned a strong reputation among PC builders. The P12 Slim PWM PST is a 120mm case fan with a remarkably slim 15mm profile—10mm thinner than standard fans. This makes it ideal for small form factor (SFF) builds where space is tight. Its speed ranges from 200 to 2100 RPM, and it features PWM Sharing Technology (PST) for daisy-chaining multiple fans. At maximum speed, noise remains low thanks to an optimised motor design. This fan is an excellent choice for compact cases, slim radiators, and any scenario where standard 25mm fans won't fit.

Compatibility Guide

This fan fits any 120mm fan mount, including case fan slots and radiator brackets. The 4-pin PWM connector plugs directly into your motherboard header, and PST allows you to chain multiple fans together, reducing cable clutter. The thin 15mm thickness means it can be installed in narrow spaces, such as behind the motherboard tray or under a low-profile CPU cooler. However, due to reduced static pressure compared to 25mm fans, it is best paired with low-density radiators or open-air case panels. Always check that the included screws are compatible with your radiator.

Product Info

The ARCTIC P12 Slim PWM PST sits at the entry to mid-range of the cooling market, offering excellent value for its price (~$9–10 USD). It has been available since 2021 and comes with a 6-year manufacturer warranty. Power consumption is just 1.44W at full speed, making it very efficient. The fan is sold individually and includes mounting screws and a PST cable. Its market position is as a specialised slim fan for space-constrained builds rather than a high-airflow mainstream cooler.

Best Use Cases

SFF PC builders: At only 15mm thick, this fan fits in compact cases like the Cooler Master NR200 or Fractal Design Node 202, where standard fans would interfere with components. Silent PC enthusiasts: The fan can spin as low as 200 RPM, producing virtually no noise. PWM control ensures quiet operation at idle and low loads. * Slim radiator setups: Ideal for use with radiators 20mm or thinner, such as the Alphacool NexXxoS ST30 or similar, to maximise space efficiency.

Things to Consider

The reduced thickness comes with a trade-off in static pressure. For high-density radiators (e.g., 30mm+ thick or high FPI), this fan may not provide sufficient cooling. In such cases, consider the standard 25mm ARCTIC P12 PST instead. The fan cable is relatively short (approx. 400mm), so plan your cable routing carefully. Also, while PST is convenient, daisy-chaining more than three fans may strain a single fan header; check your motherboard's header current rating. Overall, this fan is a specialist tool for slim builds, not a universal replacement for full-sized case fans.
