Specifications
The HD120 RGB is a PWM fan and rated at 1725 RPM, and different from the SP120 RGB which is a voltage control fan rated at 1400 RPM. Interestingly, despite the higher rated speed, the max CFM rating is barely above that of the SP120 RGB fan.
Packaging & Contents
The Corsair HD120 comes in 3 different bundles; a triple pack with a fan controller, a single pack with a fan controller, and also just a single pack with just one fan inside. This provides you will plenty of options should you choose to increase the number of HD120 fans at a later stage in your PC build.
The HD120 fan blades are of a semi-translucent white that, when spun, helps to disperse the light emitted from the LEDs embedded along the inner rim.
The fan controller actually comes in 2 parts; the LED controller and 4-pin fan hub that allows you to connect up to 6 fans. You will need to connect up the fans in sequential order starting from the number 1 port. Any breakage in the sequential order of fan connected to the hub will mean the lights after the missed port will not light up. So if you plugged in your first 2 fans into ports 1 and 2, and then the third fan into port 4, then that third fan will not light up.
The fan controller plugs into the fan hub, and has three buttons: Speed, Mode and Color. The Speed button toggles through the lighting mode speed with choices of High, Medium and Slow. In practice you will notice 3 distinct animation speeds and you choose according to your prefereance. The Mode button toggles through the various lighting modes- Demo mode, Static, Breathing, Flicker, Sequential, Marquee, Rainbow- and there are 7 modes to choose from. The color button toggles through the various colors supported by the RGB LEDs; White, Red, Orange, Yellow, Green, Blue and Violet.
The 6 way fan hub and the LED controller is powered by a SATA power connector, which is a godsend for not using the rapidly aging 4-pin molex.
Both the fan controller and the fan hub come with pre-applied 3M double sided tape to help secure them on to case panels. Also included is an optional cable which plugs into the controller and can be wired to push buttons to help activate the 3 buttons on the controller. The functions are marked clearly, and as an example one could wire these to power/reset buttons on a case to use the controller from the front of the case instead.
