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.

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
