Note28that it is possible to control more than three fans by connecting two29fans to one PWM output. The EMC6W201 will be available in a 36-pin30QFN package."31 32The device is functionally close to the EMC6D100 series, but is33register-incompatible.34 35The driver currently only supports the monitoring of the voltages,36temperatures and fan speeds. Limits can be changed. Alarms are not37supported, and neither is fan speed control.38 39 40Known Systems With EMC6W20141---------------------------42 43The EMC6W201 is a rare device, only found on a few systems, made in442005 and 2006.
