Scythe Kaze Flex 120mm PWM RGB 1800 RPM Quiet Case Fan

The Kaze Flex fan series combines the award-winning technology of the Kaze Flex fan with an optical revision and RGB LED lighting.

Features

  1. Quiet PC PWM cooling fan
  2. Closed Fluid Bearings
  3. Eight RGB LEDs
  4. 35.8 dB(A) / 1800 RPM / 79.8 CFM
  5. MTBF 120,000 hours

The Kaze Flex RGB PWM series combines the award-winning technology of the Kaze Flex fans with an optical revision and RGB LEDs. The all-black frame and decouplers emphasise the translucent fan blades illuminated by eight LEDs. A 4-pin 12V RGB connector allows regulation by standard RGB controllers. Thanks to an additional pass-through plug, several fans can be chained together. The outstanding performance of the Kaze Flex range remains untouched. The Sealed Precision FDB bearing ensures a service life of more than 120 000 hours. A regular RGB fan version is also available.

RGB illumination

Eight RGB LEDs arranged in a ring around the fan motor generate a consistent and powerful illumination of the translucent fan blades. The LEDs are operated by a standard 4-Pin RGB cable that can be directly controlled by the common RGB system of various motherboard manufacturers. Compatible, among others, are systems like ASUS Aurora Sync, ASRock RGB LED, MSI Mystic Light Sync and Gigabyte RGB Fusion.

Sealed Precision FDB

In order to guarantee an exceptionally high level of stability and durability, the fans from the Kaze Flex Series are equipped with a self-contained fluid dynamic bearing (Sealed Precision FDB). The bearing and the spindle are made entirely of high quality compressed metal and lubricated by a special oil film resistant to temperatures of up to 250°C. This drastically reduces friction, ensuring smooth operation and minimised wear, which results in an average life-span of 120,000 hours.

Integrated Anti-Vibration System

The Kaze Flex fan series is equipped with vibration and shock absorbing rubber pads which cover the tunnelless mounting holes. These decouplers effectively eliminate possible vibrations and allow low-noise operation.

Other features

The Kaze Flex 120 RGB PWM comes with a 50 cm long sleeved 4-Pin cable as well as a standard 12V 4-Pin cable for RGB control with an additional pass-through plug. This allows easy installation in almost any system configuration. An adaptor for direct connection to the power supply is also included.

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.

    105mm between screw holes:120mm fan size


  • 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.

“Superb Customer Service”

“I configured and paid for my first PC but unfortunately I made a mistake with the components meaning there was too much fan noise for my taste. I spoke to customer services and they let me return and exchange for a more suitable build without any of the usual reluctance you expect. The advisors and customer agents are all first class and I will definitely use them for all my future business. The desktop I got is gorgeous, sleek and most importantly for me, completely silent.”
