Info updated on:

Perform hardware diagnostics on your Mac and monitor a wide range of computer parts, including CPU, GPU, logic board, memory and palm rest as well as temperature and fan speed. Get notifications when components get too hot and increase the fan speeds.

TG Pro allows monitoring the temperature of various hardware components, including your CPU, GPU, logic board, memory and palm rest. Likewise, it can perform various types of diagnostic tests on the components. This way, you can make the necessary adjustments, mainly those related to fan speed. It takes advantage of the temp sensors in your machine to acquire such data. Luckily, it supports all Mac models from 2008, so it is quite unlikely that it does not work with your hardware.

The application runs unobtrusively from the Menu Bar, and you can access its main window from the icon there. It is quite convenient that you can filter components by type or just view all of them as a list. Likewise, there are bars to show the current temperature for each of them, which has different colors indicating if it is acceptable, near the recommended threshold or too high. Moreover, that same information is available in degrees, and both Celsius and Fahrenheit are supported. It is also good that you can get data about fan speed and, fortunately, you can create autoboost rules that increase the fan speed when the temperature exceeds a given value. more

Thanks for reviewing TG Pro! Just to clarify, it does have specific warnings if a user wants to lower the fan speeds. By default this option is off so the fans can be increased (and only to the max rpm specified by the hardware), which is safe.

It's not possible to damage the hardware at all since the fans can't be turned off or lowered without explicitly turning on an option (that also has a warning).
