Arctic Cooling Arctic F9 Pro PWM 92mm Rear Case Fan

High Performance Ultra Quiet PWM Case Fans

Arctic’s PWM case fans are a little different to normal PWM fans. This is thanks to the patented PST (PWM Sharing Technology). The PST feature allows up to five of these fans to be daisy chained together, meaning the motherboard can power and regulate all five fans from one PWM fan header from the motherboard.

Features

Patented PWM Sharing Technology (PST)
Best noise-performance ratio
Patented fan holder eliminates vibrations
Patented vibration absorption
Fluid dynamic bearing extends service life
Compatible with screwless mounting

How does PST lower the temperature of the entire case?

CPU and graphics cards generate an increasing amount of heat which leads to high ambient case temperatures. Some users will use more case fans to keep the heat under control. However, this often produces more noise, and energy will be wasted as all fans run at full speed even after the case temperature is lowered.

Using the new ARCTIC F Pro PWM fans can solve these problems with little hassle. The fan speed of these fans can change according to system temperatures thanks to motherboards BIOS features. Furthermore, the innovative patented PST function can allow up to five fans (including CPU fans) to be connected to the ARCTIC F Pro PWM fan. The speed of all the fans in this PST system is now centrally controlled by a single PWM signal via BIOS.

As a result, when the system temperatures increases, all fans in the PST system will run faster to lower the temperature. Likewise, when the temperatures decrease the fan speed will be lowered accordingly. This is ideal if you want to maintain cooling during high load but require quieter cooling during idle periods.

In conclusion, the advantages of PST are:

Control the speed of different fans with only one PWM signal from the mainboard.
Case ventilation can be achieved in a quiet and efficient way. More fans run slower at idle, which deliver sufficient cooling at a much quieter operation than before.
Better energy saving as fans are not always at full load.

PLEASE NOTE - Arctic Cooling measure noise levels in Sone (loudness) instead of dB (sound intensity). The loudness depends upon your ears response curves and tells you how noticeable a certain noise is.

FAQ

How do I measure fan size?
The size of fan you need will generally be determined by the size of the fan fitting position in your PC case. The sizes of all the fans on our website are shown as measured along any one of the fan’s four sides, NOT the distance between the fan’s screw holes! Our most popular fan size is 120mm, followed by 80mm. This isn’t really dictated by customer preference, but more by recent designs of PC cases.

As for the thickness (depth) of the fan, generally 25mm (1 inch) is by far the most common depth, although smaller fans can have shallower depths such as 15mm or even 10mm. All our fans are 25mm thick unless otherwise stated. If you have any questions about which fan you should order, please don’t hesitate to get in touch.

If you know the distance between the fan mounting screw holes but don’t know what fan size to order, please see the following table. Note that the mounting hole measurements shown below are taken horizontally or vertically between the holes and not diagonally.

I received a small cable (resistor) with my fan; what is it for?
The resistor cable (also called Ultra Low Noise or ULN cable) is designed to allow the fan to run slightly slower for even quieter operation. The benefit in lower running noise is significant. Although the airflow will be reduced slightly, this usually has minimal effect on PC temperature. We would generally recommend using the ULN resistor cable for best results in almost all circumstances.
How can I tell which way the air blows through the fan?
Hold the fan so that the round fan sticker is facing you. You are looking at the rear of the fan. When you plug the fan in, the air will be blowing towards you. If you want a fan to act as an air intake, then the fan sticker will be facing the inside of the case. Some fans also have two small arrows moulded into their plastic housing - one arrow shows the direction of airflow, and the other (at 90°) shows the direction of blade rotation.
Is it possible to use a 4-pin PWM fan or CPU cooler with a motherboard which has only 3-pin fan headers on it?
Electrically, there is no problem doing this - the fourth pin on the fan cable is used purely for PWM control and is not needed in order for the fan to run. So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.

The only other problem to consider is that occasionally, components immediately adjacent to the motherboard fan header can get in the way of the larger 4-pin fan connector, physically preventing connection. This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.

Another avenue to explore is the possibility of using a bay-mounted fan controller. Several models are available now which provide 4-pin fan headers, so this is an easy way to use 4-pin PWM fans in a PC system which has only 3-pin fan headers on its motherboards. When using this method, you may find it necessary to disable any fan warning settings in your motherboard BIOS, since the motherboard may incorrectly believe that its CPU fan has failed when the fan is connected to a fan controller rather than directly to the motherboard itself.
