| Description | |
| ----------- | |
| From the datasheet: | |
| "The EMC6W201 is an environmental monitoring device with automatic fan | |
| control capability and enhanced system acoustics for noise suppression. | |
| This ACPI compliant device provides hardware monitoring for up to six | |
| voltages (including its own VCC) and five external thermal sensors, | |
| measures the speed of up to five fans, and controls the speed of | |
| multiple DC fans using three Pulse Width Modulator (PWM) outputs. 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. Known systems with this device: | |
| * Dell Precision 670 workstation | |
| * Gigabyte 2CEWH mainboard |
