ARCTIC fans for static pressure and for airflow - What are the differences?

arctic p fan faq

With the introduction of the 120 and 140 mm P-fans, we have expanded our fan range with a completely new product group. While the F-Series fans are designed for high airflow, the P Series fans are designed for high static pressure.

Read on to learn more about the high static pressure P-fans and to learn which applications our high-flow F-fans are more suitable for.

ARCTIC P-fans - Ideal for heatsinks

Thanks to the completely new fan design with five strongly curved blades, the P-fans have a much higher static pressure than the F-fans.

In internal tests we measured increased static pressure up to to 33 % for the P-fans compared to the F-fans. With the P-fans, a higher level of cooling is achieved, especially with increased air resistance (on radiators, heatsinks, or close meshed fan grilles on housings). Fans of the P-family are therefore particularly suitable for use on heatsinks.

In addition, the PWM-equipped P-fans (PWM, PWM PST, PWM PST CO and BioniX) feature a new motor generation that offers several advantages:

  • Wide RPM range
  • Significantly lower power consumption
  • Less vibration from commutation

ARCTIC F-fans - high airflow

The F-Series fans, in contrast, are optimized for high airflow and, in cases of low air resistance, transport a large amount of air. They are thus especially ideal as case fans.

The operating noise of the F-fans is very similar to White Noise, which is generally perceived as a neutral and unobtrusive background noise.

Of course, all ARCTIC fans can still be installed in push or pull configuration.

FAQ for ARCTIC P-fans

Static pressure and air flow in fans - what does that mean?

In addition to the size and the speed of a fan, air flow and static pressure are two important metrics for evaluating the performance of a fan.

For air flow, the transported air volume is measured in cubic meters per hour (m³ / h) or alternatively in cubic feet per minute (CFM). The pressure, however, is measured in mm H²O, with the so-called (milli-) meters of water gauge and corresponds to the pressure in the given water depth.

Information about the air flow therefore gives you information about the maximum amount of air that can be moved by the fan, whereas figures about the static pressure provide information about the pressure with which the air is transported.

Why do you need a high airflow in fans?

Air is a very poor conductor of heat. Without any air circulation, powerful PC components would quickly thermal throttle due to heat accumulation.

The rotational movement of the fan blades creates a mechanical air flow. The airflow transports warm air away and draws in new, cooler air to the heatsink, thus preventing thermal throttling. This, of course, has a big influence on the cooling performance.

What is static pressure important for?

Static pressure is important for cooling performance in situations where completely free air circulation impossible. This may be, for example, a close-meshed housing inlet, or radiators and heatsinks, with their closely spaced cooling fins. In order to guarantee high air circulation through these resistors, the highest possible static pressure is required.

Without a correspondingly high static pressure, the desired air circulation is not achieved, whereby cooling power is lost.

Are the P-fans compatible with my existing Freezer 33?

Yes, the 120 mm versions of the new P-fans can be easily mounted to existing Freezer 32 and Freezer 33 models. This should lead to improved cooling performance.

At the same time, you can benefit from the new engine technology with all its advantages and customization options with the color variations of the PWM-equipped P-fan.

Why are no anti-vibration pads included?

Thanks to the new motor technology of the PWM-equipped P-fans, only 5 % of the commutation vibration of a conventional DC motor is generated. Modern sinus-magnetizing guarantees an even power distribution, which eliminates the need for additional rubber buffering.

My PWM fan stops regularly - is it defective?

No, the fan is not defective. Thanks to the new engine technology, our new PWM fans can operate in a 0 db mode. If the PWM signal falls below 5 %, the fan stops and thus operates completely silently.

If the operating load of the computer rises and more cooling is necessary, the fan is automatically informed via PWM and starts again.

How do I configure my PWM settings?

You can only configure the PWM settings via your BIOS. Please consult your motherboards user manual for additional information.

What is the PWM sharing technology?

An explanation of how the PWM sharing technology (PST) works can be found here:

How many fans can I connect in series via PWM PST?

Up to four fans can be connected via the ARCTIC PWM PST technology.

I want to mount the Bionix P140 to my AIO radiator, but the screws do not fit. What am I doing wrong?

When replacing fans of non-ARCTIC compact water coolers with ARCTIC’s Bionix P140, it’s possible that the pre-assembled screws may not fit. Compatible screws are available from ARCTIC support. Please send a request with attached proof of purchase to: cs@support.arctic.ac
