Field of View (FOV): FOV defines the height and width of the in-game view. These settings will also give you a nice FPS boost if you meet the minimum requirements to play this game.
“Auto” keeps the default behavior, but opening up “Custom” allows you to set a specific RPM value, or set a target temperature. The Mac Pro 4,1 and 5,1 default fan settings (like most Macs) are aiming for very silent operation but can result in (too) high Temps. Below we have listed our recommended, optimized settings for good performance and better visibility when playing Warzone. When it starts, you’ll see a list of all your fans and the option to set custom controls. Get started by downloading the Macs Fan Control app and moving it to the Applications folder. It’s also possible that running fans at max speed for extended periods could lead to damage, so try not to torture your laptop. With either option, you should monitor the temperatures of your CPU and other components and make sure you’re not causing damage to your system. Keep in mind that this will make your system run a lot hotter, and could lead to system instability if you let it go too far. On the other hand, if you hate fan noise, you can manually turn them down. This makes a lot of noise, which is why the auto-control tries to slow it down.
Usually, this kicks in before the temperature gets too high, but you can manually push your CPU farther by turning the fan speed up farther than Apple usually allows. Your Mac throttles your CPU when it gets too hot, slowing it down significantly until the temperature gets under control.
