FanCtrl

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. What you need is lots of fans inside your case and a smart way to control their speed. The second of the two requirements can be achieved with FanCtrl (or FanControl). The mechanism behind it is simple.

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. 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. The problem arises if you're dealing with older design three or two-pin fans. Those will not work with speed controlling software.

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. Most fan controllers don't display system-related information unless it has to do with the fans themselves. With this application, you can very easily monitor temperatures both for your CPU and ultimately for your GPU. This way you can keep an eye on all component temps and get an idea about how cool or hot your PC is.
