Gelid Solutions Silent 14 PWM, 140mm PWM Quiet Cooling Fan

Gelid’s Silent series case fans have been designed for silent enthusiasts that provide excellent airflow without increasing noise levels, all at an affordable price.

Features

  1. Pulse Width Modulation (PWM)
  2. Silent Operation w/ Rubber Fan Mounts
  3. Optimised Fan Blades
  4. High Airflow & High Static Pressure
  5. Long Lifetime (50,000 hours MTBF at 40°C)

Designed for advanced users, GELID’s Silent PWM fans provide additional airflow by using Pulse Width Modulation (PWM) to automatically adjust fan speed according to the CPU load. The fan can be idled down and thus be much quieter. An intelligent IC has been integrated into the fan’s PCB to exploit the mainboard’s BIOS software. This technology is more efficient and convenient than using an external fan controller to adjust the fan speed.

Each fan impeller has been individually balanced using the latest technology to guarantee steady, unwavering operation. To add to the silence, fan mounts replace traditional screws and are made of high quality, temperature resistant, extra long lasting rubber to stop vibrations from the fan motor from travelling into your PC case.

How does PWM work?

Pulse-width modulation (PWM) delivers a digital signal. The advantages of using a digital PWM signal compared to an analogue controller are:

  • PWM control calculates the appropriate cooling performance according to CPU and System temperature
  • PWM control of your mainboard will always adjust to the correct cooling
  • PWM control operates without generating any heat

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.
