Cooltek Silent Series Fan 120 RGB, 1200RPM

The Cooltek Silent Fan 120 RGB extends the range of their popular Silent Fan series with RGB illumination. The fan features 18 RGB LEDs arranged around the edge of the fan to produce a ring that give intense illumination, which is picked up and reflected

The fan is supplied with a male and female version of a 4-pin RGB connectors. The female connector is design to attach to a motherboard that features 4-pin RGB headers, for example ASUS AURA. The male connector is design to allow you to connect a second RGB fan in series.

To use the control software of compatible motherboards (such as ASUS AURA or MSI MYSTIC LIGHT), the Silent Fan 120 RGB has a 4-pin RGB connector. If more than one Cooltek Silent Fan 120 RGB is used in the system, these can also be connected in series.

The Silent Fan 120 RGB rotates at a maximum of 1,200 rpm and generates a volume flow of approximately 36 CFM at a maximum noise level of just 20.0 dB(A). Hydraulic bearings guarantee quiet operation and a life expectancy of 30,000 hours. The scope of supply includes a set of lug screws and practical silicone washers for decoupling the louver.

The fan is connected via a 3-pin Molex connection, so it can be controlled via the mainboard or a fan control. In addition, the Silent Fan 120 RGB is equipped with a 4-pin RGB plug. If you have a motherboard with 4-pin RGB headers (such as ASUS Aura or MSI Mystic Light), you can connect the Silent Fan 120 RGB directly to the motherboard and control the lighting effects through the motherboard’s software. In addition, the Silent Fan 120 RGB has a male 4-pin RGB connector, which allows you to connect additional RGB LED fans or other components with 4-pin RGB headers in series (max rated power 3A = 15W at 5V or 36W at 12V ). If the fan is to be connected directly to the power supply, a 3-pin to 4-pin Molex adapter 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.

  • 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.
