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. You can download Macs Fan Control free here.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. Macs Fan Control gives you full control over your Mac's fans, so you can decide how loud or efficient they should be.

There are no obvious drawbacks to speak of. What's more, the application is compatible with third party hardware. Also, it allows you to control the speed of each fan.

The application can monitor hardware temperatures and fan speeds on your Mac. Its real-time monitoring features work even if you have changed your hard drive or SSD. The best part is that Macs Fan Control provides full support for third party hardware as well. Alternatively, you can set a constant RPM value or let the system control your fans automatically.

You can set up your own minimum and maximum fan speeds, for each fan, on a separate window. Each fan is presented together with its current, minimum and maximum RPM values. Fans are listed on the left side of the window and hardware temperatures are displayed on the right side. What's more, the application allows you to control the fans, as the name suggests, to reduce noise or cool down your hardware if it overheats.Īll the information you need is presented on a compact user interface. Besides reassuring you that they are still spinning, the application can provide you with other useful information, like their RPM, the CPU and HDD or SDD temperature and more. Although it is physically impossible to look at a Mac's fans, you can use Macs Fan Control to find out much more then you would when looking at them. Keeping an eye on a computer's coolers is always a smart idea.
