  16From the datasheet:
  17
  18"The EMC6W201 is an environmental monitoring device with automatic fan
  19control capability and enhanced system acoustics for noise suppression.
  20This ACPI compliant device provides hardware monitoring for up to six
  21voltages (including its own VCC) and five external thermal sensors,
  22measures the speed of up to five fans, and controls the speed of
  23multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note
  24that it is possible to control more than three fans by connecting two
  25fans to one PWM output. The EMC6W201 will be available in a 36-pin
  26QFN package."
  27
  28The device is functionally close to the EMC6D100 series, but is
  29register-incompatible.
  30
  31The driver currently only supports the monitoring of the voltages,
  32temperatures and fan speeds. Limits can be changed. Alarms are not
  33supported, and neither is fan speed control.
