| | 9 | \fBpwmconfig\fR will attempt to stop your fans, one at a time, for |
| | 10 | approximately 5 seconds each. This may cause your processor |
| | 11 | temperature to rise. Verify that all fans are running at normal speed |
| | 12 | after this program has exited. |
| | 13 | \fBpwmconfig\fR does its best to check that the fans are spinning when |
| | 14 | they are supposed to, but due to the diversity of available |
| | 15 | motherboards and fans, it shouldn't be blindly trusted. Always verify |
| | 16 | by yourself. |
| | 17 | |
| | 18 | It is strongly recommended to run \fBpwmconfig\fR at a time when there |
| | 19 | is no significant system load, to minimize the risk of overheating. |
| | 20 | |
| 15 | | It attempts to briefly stop each fan using the PWM controls. It then |
| 16 | | attempts to restore each fan to full speed after testing. However, it |
| 17 | | is \fBvery important\fP that you physically verify that the fans have |
| 18 | | been returned to full speed after the program has completed. |
| | 28 | When a connection is established between a PWM control and a fan, |
| | 29 | \fBpwmconfig\fR can generate a detailed correlation, to show how a |
| | 30 | given fan is responding to various PWM duty cycles. |
| 20 | | .SH WARNING |
| 21 | | This program will stop your fans, one at a time, for approximately 5 seconds each. |
| 22 | | This may cause your processor temperature to rise. Verify that all fans are running |
| 23 | | at normal speed after this program has exited. |
| | 32 | Lastly, \fBpwmconfig\fR will enter in \fBfancontrol\fR configuration |
| | 33 | mode (unless you decide to skip that part.) In this mode, you are |
| | 34 | invited to enter several parameters which will determine how the |
| | 35 | \fBfancontrol\fR daemon regulates the speed of one or more fans in |
| | 36 | your system based on temperature measurements. In particular, you will |
| | 37 | have the opportunity to establish mappings between fans and |
| | 38 | temperature inputs, define the temperature range over which the speed |
| | 39 | of the fan should be adjusted dynamically, the minimum speed at which |
| | 40 | the fan should spin, etc. See fancontrol(8) for additional |
| | 41 | information. |

| | 43 | .SH BUGS |
| | 44 | The term "PWM" is used because most fan control systems in computers |
| | 45 | are based on pulse width modulation. Some motherboards however use DC |
| | 46 | variation instead. So, the term "PWM" should be seen as a generic term |
| | 47 | for "fan speed control", regardless of the actual method used. |
