Delivered what they said, when they said.

Basically the PC turned up well within the 7 day build & delivery period they stated, and it was as described. Not much else... TIMOTHY BARNETT, 24th October 2014 (via Trustpilot)

Arctic Cooling Arctic F9 PWM Fan

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.

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

  1. Patented PWM Sharing Technology (PST)
  2. Extremely quiet
  3. High air flow and static pressure
  4. Low noise impeller
  5. Fluid dynamic bearing extends service life

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 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 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:

1. Control the speed of different fans with only one PWM signal from the mainboard.
2. 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.
3. 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.

Customer Reviews

Happy with mine!

,

Bought couple of these and fitted on my graphics card. It's GTX260 with PWM fan control and working fine controlling both of these using the "pass through" connection. Tested fine on motherboard connection too. At 25% getting ~550rpm and very quiet. Personally I like the white on black appearance too.
