MINPWM The PWM value to use when the temperature is below MINTEMP. MINSTOP The minimum speed at which the fan still spins. Safe value to be sure it works, even when the fan gets old. MINSTART Sets the minimum speed at which the fan begins spinning. MAXTEMP The temperature over which the fan gets switched to maximum speed. MINTEMP The temperature below which the fan gets switched to minimum speed. Thenįancontrol can check the fan speed and restart it if it stops FCFANS Records the association between a PWM output and a fan input. Temperature sensors should be used for calculation of new values for theĬorresponding PWM outputs. FCTEMPS Maps PWM outputs to temperature sensors so fancontrol knows which The configuration file is still up-to-date. DEVNAME Records hwmon class device names. This lets fancontrolĬheck that the configuration file is still up-to-date. INTERVAL This variable defines at which interval in seconds the main loop ofįancontrol will be executed DEVPATH Maps hwmon class devices to physical devices. Various variables available for changing fancontrol's behaviour: Since most of you are going to use pwmconfig(8) script, theĬonfig file syntax will be discussed last. Alternatively you can write this file yourself using the Which lets you interactively write your configuration file forįancontrol. Slightly warmer, just be sure to have a temperature alarm and/or shutdownĬall, in case some fan fails, because you probably won't hear it anymoreįor easy configuration, there's a script named pwmconfig(8) In practice it doesn't seem to be a major issue, the fans will get Most fans aren't designed to be powered by a PWMed voltage. Maybe you shouldn't use fancontrol at all. So if you plan to use these components in 50 years, Temperatures there will be a higher wearout of your other hardwareĬomponents, too. Mainboard, in addition to the risk of burning your CPU, at higher Please be careful when using the fan control features of your Temperatures and sets the corresponding PWM outputs to the computed Reads its configuration from a file, then calculates fan speeds from This way you can keep an eye on all component temps and get an idea about how cool or hot your PC is.Fancontrol - automated software based fan speed regulationįancontrol is a shell script for use with lm_sensors. With this application, you can very easily monitor temperatures both for your CPU and ultimately for your GPU. Most fan controllers don't display system-related information unless it has to do with the fans themselves. The idea behind the fans working with these types of programs lies in the PWM controller which is basically represented by the fourth pin on all fan connectors. Those will not work with speed controlling software. The problem arises if you're dealing with older design three or two-pin fans. Now, in most cases you'd be dealing with a four-pin version which ultimately means you can control the speed of your fans through any specialized software, such as FanCtrl. When you install your fan in the case and place the connector on your motherboard, you'll notice there's a number of pins on the fan. The second of the two requirements can be achieved with FanCtrl (or FanControl). What you need is lots of fans inside your case and a smart way to control their speed. If you're relying on your PC heavily, regardless of the reason, be it gaming or programming, there's no doubt the temperature inside your components is spiking up like crazy.
