The CORSAIR Commander PRO controller makes your live easier if you want to connect lots of compatible RGB fans inside the case, LED strips, but also control the LED light show in detail. The device permits monitoring of system temperatures from the included thermistors, but also connect other LINK-compatible hardware to the dual USB 2.0 headers. It measures 133mm x 69mm x 15.5mm so its slim form factor allows installation in most computer cases.
