For my day to day task it's not worth it. I can make my system cool down a good 5 degrees celsius with my own custom changes but at a cost of considerably louder fan speeds. Perform your normal tasks and see if the changes you made are 1) working like you envisioned and 2) worth the extra heat or sound emanating from your machine. Now you should monitor your system and the temperatures. If you decide that you want these changes to persists after a reboot do the following.Ĭheck the Autostart minimized with system (recommended) box. You can keep an eye on your sensor value to see if the change you applied makes a difference to your liking. You'll immediately hear a change in fan speed once you click OK.
We left the temperature range as default. Here we choose Ambient temperature as our sensor. Or you can choose to set a Sensor-based value where given a certain temperature on a specific sensor one the system, the fan can start to increase speed and go to its maximum speed at yet another temperature for that same sensor. You can use the slider to manually set a constant fan speed at whatever you desire.Next to the EXHAUST section, click Custom.We can decide to override the settings for INTAKE and EXHAUST.

Let's for example decide that we want to make certain that our Mac gets the most amount of fresh cool air into the system. You'll now see a list of Fans that you can manually override on the left and a list of current operation temperatures on the right.
If you think that you still want to go ahead and manually control your Mac fans, here's what to do. So be aware that fiddling with your Macs designed specifications will indeed break warranty and can even break your Mac. At worst, you can completely destroy your hardware components if you allow temperatures to rise too greatly with adding sufficient cooling. But be warned! Some warningsĬhanging your fan speed can cause a minimum greater wear and tear on your components. And vice versa, if you want quiet operation for a long as possible, then limiting when your fans speed up or slow down may be in your best interest. If you are on that doesn't care about fan noise and want "ALL THE POWER" then running your fans at higher spec to keep temperatures lower for longer may be what you're looking for. Since the tendency is for quieter computers, that will also mean you'll have a tendency for throttling your CPU due to higher temperatures. Apple tends to configure its hardware towards quiet operations.
Faster fan speeds means louder computers. Sufficient cooling means faster fan speeds. In order for the CPU to not throttle its frequency to a lower state, sufficient cooling must be available to avoid high operating temperatures. Making it run your tasks slower as a result. However, the lowering of the frequency also lowers the performance capabilities of the CPU. This lowering of frequency allows the CPU to run less power and in turn run cooler thus lowing the operating temperature. If a CPU starts to run at too high of an operating temperature, it will have to throttle its frequency to a lower setting. That being said, even Apple is a prisoner to the hardware specs.

It ensures that your Mac being a MacBook, MacBook Pro or even a Mac Pro can function with decent capabilities while maintaining stability and safe operating temperatures. As mentioned, Apple does its homework when it comes to what fans should run at what speeds for the amount of heat and power being produced and used. If you are one to leave well enough alone, then this is not something you'd want to delve in to. You can take more direct control over your Mac's fan speeds with the Macs Fan Control app! However, sometimes you may wish to forego the quiet for cool. And they do a pretty decent job of it too. The goal for Apple is to give you the best possible performance while keeping the system as quiet as possible all whilst using the least amount of power. Apple takes great strides to ensure that your Mac thermals run well within the hardware specifications automatically without consumer intervention.
