17 | Description | |
18 | ----------- | |
19 | ||
20 | From the datasheet: | |
21 | ||
22 | "The EMC6W201 is an environmental monitoring device with automatic fan | |
23 | control capability and enhanced system acoustics for noise suppression. | |
24 | This ACPI compliant device provides hardware monitoring for up to six | |
25 | voltages (including its own VCC) and five external thermal sensors, | |
26 | measures the speed of up to five fans, and controls the speed of | |
27 | multiple DC fans using three Pulse Width Modulator (PWM) outputs. Note | |
28 | that it is possible to control more than three fans by connecting two | |
29 | fans to one PWM output. The EMC6W201 will be available in a 36-pin | |
30 | QFN package." | |
31 | ||
32 | The device is functionally close to the EMC6D100 series, but is | |
33 | register-incompatible. | |
34 | ||
35 | The driver currently only supports the monitoring of the voltages, | |
36 | temperatures and fan speeds. Limits can be changed. Alarms are not | |
37 | supported, and neither is fan speed control. | |
