Scythe Scythe GlideStream 120mm PWM SC Case Fan

The GlideStream 120mm PWM PC fan’s main feature is the “Slide Switch” that alters the maximum speed of the fan to three different settings, low, medium and high.

The GlideStream 120 PWM PC fan combines all the positive features of the GlideStream fan series with additional technical detail - a three step slide switch for limiting the maximum speed (800/1150/1500 rpm). This allows an easy adjustment of the fan to different application areas starting from “ultra silent” to maximum cooling performance for overclockers. The PWM connector means it is an ideal replacement fan for CPU coolers as well as conventional case fan. The well-known concept of “small hub and large blades” increases the airflow of the fan compared to fans with conventional hubs.

Features

  1. Slide Switch for three different maximum fan speeds
  2. Exceptionally quiet from only 4 dBA
  3. Small hub and large blades create increased airflow
  4. PWM, for automatic control
  5. Supplied with rubber fan mounts

Speed limitation by three step slide switch

The Glide Stream 120 PWM fan SC has a small three step slide switch. This allows limiting the maximum speed of the fan and provides the opportunity to customise airflow and noise to the users needs. It’s possible to choose between extremely quiet operation and maximum cooling power or somewhere in between.

Optimised Air Flow

Due to the design concept “small hub and large blades” increases the flow cross section for fans with conventional fan hub. In combination with the specially adapted shape and fan blades angle increases the airflow massively. In order to keep air resistance to a minimum, the fan blades have been fitted with unique grooves.

PWM connector

The fan features a PWM connector which connects directly to the motherboard which will alter the fan speed based on component temperatures. The included 3 to 4-pin Molex adapter allows the fan to be connected to a PSU. There are also four sets of fan screws and anti-vibration rubber fan mounts for mounting the fan to a chassis.

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.

    72mm between screw holes:80mm fan size
    83mm between screw holes:92mm fan size
    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.
