Apple takes great strides to ensure that your Mac thermals run well within the hardware specifications automatically without consumer intervention. 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. And they do a pretty decent job of it too. However, sometimes you may wish to forego the quiet for cool. Or perhaps forego the cool for quiet. You can take more direct control over your Mac's fan speeds with the Macs Fan Control app!
Oct 12, 2014 When boot is fully completed (Boot Camp icon present in system tray and services lauched), manual lauch of Macs Fan Control is successfull. I therefore wrote a script in the windows startup folder to delay by 20s the lauch of Macs Fan Control which worked well. Sep 19, 2018 Macs Fan Control Version: 1.4.12 Updated: September 19, 2018 Download for Windows. (6.9 MB) Download for macOS (9.4 MB) macOS 10.7+ Downloads for older systems: Mac OS X 10.6 Snow Leopard; This program is for advanced users who know how to use it without doing harm to their macs. The authors are not liable for data loss, damages, profit loss. But which fan control mac app is more reliable that fulfills your needs? And how to use macs fan control software? These are the question which most mac users asks. Luckily, we have explained here best macs fan control software which can monitor macs fan speed. Mcculloch pro mac 60 manual.
Why bother overriding the fans
If you are one to leave well enough alone, then this is not something you'd want to delve in to. 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. https://keenasia818.weebly.com/blog/manual-duplex-scanning-software-mac. 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.
The computer's cooling fan typically operates on default presets, but for those who want to customize, Fan Control for Mac is an easy-to-use application that adds the ability to control fan operation from the user's preferences menu. The free application has no restrictions.
That being said, even Apple is a prisoner to the hardware specs. If a CPU starts to run at too high of an operating temperature, it will have to throttle its frequency to a lower setting. This lowering of frequency allows the CPU to run less power and in turn run cooler thus lowing the operating temperature. This avoids damaging the CPU. However, the lowering of the frequency also lowers the performance capabilities of the CPU. Making it run your tasks slower as a result.
In order for the CPU to not throttle its frequency to a lower state, sufficient cooling must be available to avoid high operating temperatures. Sufficient cooling means faster fan speeds. Faster fan speeds means louder computers. Apple tends to configure its hardware towards quiet operations. Since the tendency is for quieter computers, that will also mean you'll have a tendency for throttling your CPU due to higher temperatures.
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. 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. But be warned!
Some warnings
Changing your fan speed can cause a minimum greater wear and tear on your components. Maybe unnecessarily so. At worst, you can completely destroy your hardware components if you allow temperatures to rise too greatly with adding sufficient cooling. So be aware that fiddling with your Macs designed specifications will indeed break warranty and can even break your Mac.
Macs Fan Control
If you think that you still want to go ahead and manually control your Mac fans, here's what to do.

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. 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. We can decide to override the settings for INTAKE and EXHAUST.
You'll immediately hear a change in fan speed once you click OK. You can keep an eye on your sensor value to see if the change you applied makes a difference to your liking.
If you decide that you want these changes to persists after a reboot do the following.
See if the changes are worthwhile
Now you should monitor your system and the temperatures. 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.
Final comments![]()
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. For my day to day task it's not worth it. But If I only enable my changes when I use CPU intensive tasks where I'd expect more fan noise, then for my it's worth the increase in noise. What about you? Any interest in controlling your Mac thermals? What do you do about it? Let us know in the comments!
