Note +that it is possible to control more than three fans by connecting two +fans to one PWM output. The EMC6W201 will be available in a 36-pin +QFN package." + +The device is functionally close to the EMC6D100 series, but is +register-incompatible. + +The driver currently only supports the monitoring of the voltages, +temperatures and fan speeds. Limits can be changed. Alarms are not +supported, and neither is fan speed control. + + +Known Systems With EMC6W201 +--------------------------- + +The EMC6W201 is a rare device, only found on a few systems, made in +2005 and 2006.
