This way you can keep an eye on all component temps and get an idea about how cool or hot your PC is.

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. Furthermore it communicates with systemd via dbus to control the fancontrol service. It uses the KAuth module of the KDE Frameworks 5 to write the generated config file. 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. fancontrol-gui is a GUI for fancontrol which is part of lmsensors.
