Lian-Li introduced their new TR-5 Fan Controller:

The innovative device takes up one 5.25 bay, and has a full frontal LCD, showing the various fan speeds and temperatures within your chassis environment. It comes in two flavors; one metallic silver, the other, matt black.

Allowing up to four different temperatures (0 to 99 degrees Celsius ~ +/-2 degrees Celsius) and fan speeds, ranging from (1) CPU, (2) VGA, and (3 & 4) system 1 & system 2 fans, the TR-5 is more than adequate for your cooling needs. In addition, the device has an Alarm / Date and Time function, with settings for either degrees Celsius or Fahrenheit temperature display modes, at the touch of a button.

The TR-5 works on 12V DC, with 0.45A maximum current 3 pin fans. At standard factory settings, the fan speed will be regulated according to pre-set temperature ranges. These can be adjusted. You may also force the device to maintain slow/medium or high speeds, or allow it to continue in automatic mode. There is a failsafe alarm option should any fan malfunction or if the temperature sensors detect overheating. When the alarm is activated, the backlit LCD displays a flashing red color.
