Clicking on that reading will drop a large menu listing that will showcase the readings from all the other fans in your system, a Preset selector and a Preferences button. Upon firing the app, you will notice a brand-new icon in your system status bar, with the two most important real-time readings for CPU temperature and speed of the main PCU fan. SmcFanControl comes in a lightweight package that can be quickly installed on any modern macOS 10.7 or later that runs on Intel CPU. It is important to note that you can control the fan speed of your MacBook, MacBook Pro or MacBook Air laptops when they are placed on a cooling stand. Utilizing streamlined tools and eye-catching visual reporting, you can optimize fan curves and reduce the overall system temperature to the levels where you Mac will function optimally. You can not only set desired minimal fans speeds, but also create separate presets for specific use-case scenarios, for example, turn on stronger cooling when you are using your Mac for video rendering, 3D modeling or gaming, and then reduce cooling when you are browsing or working with text files. With smc Fan Control, you can monitor the temperature levels and fan speed modes in your Mac and manage temperature according to your needs. In most extreme situations when cooling becomes totally inadequate (such as in the event of cooling fan failure), your Mac can even perform emergency shutdown in order to save components from permanent failure. Since those components are rated to function with optimal speed only in a certain temperature range, overheating can cause them to reduce their working speed, and in some extreme cases even significantly throttle their speeds. This unobtrusive app is especially useful for users who are putting a lot of processing strain on their Macs, and especially for laptop users where the working temperature of the core components such as CPU and GPU can directly impact the performance levels of the entire configuration. SmcFanControl for Mac is a lightweight system utility that can help users of all knowledge levels to get full control over the function of built-in fans and oversight over the cooling status of their Mac computer.
