While these dual ball bearing fans aren't attention seekers, as they don't offer any LEDs or anything to crave attention, they are white. It's not the first time we have seen white SilverStone fans as with the SilverStone Nitrogon heatsinks we have previously reviewed, they have all been white blades to fit with SilverStone's theme. Aside from being white, there really isn't anything to differentiate these fans on the outside from other generic computer case fans on the market. Though the frame for the FM83 fan is somewhat different, but certainly not unique.
The SilverStone FM123 has a model number of GMA12025B12U-LV and the 80mm fan is GMA09225B12H-2. Both of these fans trace back to Gale Motor / Glacial Tech. These 12V DC fans have an operating voltage range from 6V to 13.2V. Both fans have a 3-pin power interface as well as a control module cable for controlling the fan speed. The design of the motor housing for the fan is in a "bullet hub design" to allow for greater aerodynamic airflow. For controlling the fan speed is a module that can be installed into an expansion slot and is just a dial that can turn the fan on or off and adjust the speed from low to high. What is nice about the fan speed controller for the SilverStone FM83 and FM123 is that it supports mounting up to three fan controllers per expansion slot bracket. If you have two or three SilverStone fans inside your chassis that are all variable speed, you don't need to occupy two or three expansion slots, but you can easily mount them all on one bracket.
