Jun 29, 2019 I have been wondering how to change my cpu and gpu fan speeds manually as I think something is overheating in my laptop when I'm playing a big game. I have tried pressing f2 when rebooting to bring up the bios but I cannot find where to control this fan speed. I have msi afterburner but the fan speed is grayed out and I can't change it. Sep 28, 2018 How to manually set your Mac’s cooling fan speeds Upon launching Macs Fan Control for the first time, you’ll notice that the interface encompasses both fan speed controls and a place to monitor real-time hardware temperatures: By default, my Mac’s cooling fans run between 2,000-2,100 RPM at idle, and that’s great. If your computer's running a little loud for your tastes, it's probably because your fans are running at full speed—even if they don't need to be. Here are a few ways to manage your fan's speed.
smcFanControl controls the fans of every Intel Mac to make it run cooler. smcFanControl lets the user set the minimum speed of the build in fans. So you can increase your minimum fan speed to make your Intel Mac run cooler. However in order not to damage your machines smcFanControl doesn't let you set a minimum speed to a value below Apple's defaults.
What's New in smcFanControl
Version 2.6:Note: Now requires OS X 10.7 or later
New
- Added french localization
- Updated sparkle updater
- smcFanControl now requires macOS 10.7 or higher
Fixed
- Crash on Macbook 12'
- Invisible text on macOS Sierra 'Dark mode

To check and monitor the Intel-based Mac OS X computer operating temperature, Mac users can download and install the freeware app CoreDuoTemp, which is also a menubar application with CoreDuoTemp Widget. Other than CPU operating temperature, CoreDuoTemp also displays indicators of CPU frequencies, CPU usage, and features multiple temperature unit °F, °C or K.
If your Mac system temperature is too high, Mac users can adjust and modify the fan speed to higher speed in order to make the Mac machine runs cooler at lower temperature. There are a few GUI (graphics user interface) based utility software that can help MBP and MacBook (and MacMini) users to control and adjust the speed of the fan cooler.
smcFanControl is one of the such fan speed control utility, to cool down MacBook (Pro). smcFanControl let users set the minimum speed for each built-in fan individually. However, in order to protect and note to damage the computer or notebook, you won’t be able to set the minimum speed to a rate which is under Apple’s defaults. So users can increase the minimum RPM speed of the fans to release and dissipate more heat and thus cool down the system. To change the fan-speeds, users need to authenticate with valid credentials of an user-account with admin privileges. Some note is that you need to check the “Auto Apply after Launch” option and add smcFanControl to Login-Items to auto apply your prefer fan speeds settings after restart, and in order not to lose the changed settings after standby, smcFanControl has to run in the background.
Another application is GPL-based open source software Fan Control from Lobotomo Software. Fan Control also modifies and adjusts the minimum fan speed. However, Fan Control can controls and adjusts the minimum fan speed by increment of 1 unit constantly depending on the current CPU temperature and user’s preset preferred temperature level automatically. Fan Speed also won’t modify the original automatic fan speed control for safety purpose.
While increasing the RPM speed of the fans in MacBook (Pro) can make the laptop and notebook cooler, however, it will consume more power and thus reduce the battery life slightly. And it could shorten the life of the fans too, and the noise of the fan will be louder slightly too.
