[M] Scythe Kaze Master II Fan Controller Review
 

The new fan controller from Scythe has retractable buttons which are useful in a number of cases, but also includes features like 12V start-up voltage, alarms or power feed control. The VFD display in front lets us check the current fan speeds and temperatures (in degrees Celsius or Fahrenheit) for each channel.
