Mac & Boot Camp Fan Control is a simple application in terms of offered functionality, but an important one if you're trying to achieve the perfect balance between having a well-cooled machine, and as little noise as possible coming from it. In other words, if you drop fan speeds too much, your machine might end up shutting down due to heat issues. These are relevant because if you want to avoid overheating and other serious issues, fan adjustments have to be made in accordance with the displayed data. It will display component temperatures, giving you values for CPU cores, GPU, RAM, HDD, and ODD. Now, once you've operated your desired changes, do not hesitate to also check the right, smaller pane within the program's window. Further to the right, you can choose to input a custom speed, using values between the displayed minimum and maximum rotations. The minimum, current, and maximum speeds are displayed.

On the left side of the app window, you'll find the actual fans, depending on their positioning within the system. Functions and information are well separated from each other.

It integrates well among other OS utilities, but it is clear that its purpose is to offer functionality and not surprise through its looks. The program itself won't really surprise you with its futuristic look. The app was created to help users increase or decrease fan speeds and ultimately to keep an eye on component temperatures. Now, why would you want to use this app? Simply to keep track of your device's core temperatures and fan noise level.
#FAN CONTROL IMAC PRO#
If you're a Macintosh user, be it an iMac or MacBook Pro user, and have Windows OS installed on your machine, then this app will work for you. Applications/smcFanControl.Mac & Boot Camp Fan Control is an application that targets a very specific group of users. However, after starting Macs Fan Control, it writes my desired target speed to smc so that still works! Great! Here is how that looks like: By setting the minimum speed to 800rpm, the lowest ever achieved rpm that I got is around 960rpm.Īfter rebooting, the minimum fan speed got reset (by the system supposedly) to the original 1200rpm. It seems that the fan and its control logic can’t go well below that. Lowering the minimum speed below 1000rpm does not yield the desired results. Yet, there is still considerable airflow and everything looks and feels great. This results in almost complete silence in my environment. Applications/smcFanControl.app/Contents/Resources/smc -f Reading out the smc info now looks like this: If you need further explanation, the GitHub repo provides a detailed readme.Īfter that, use Macs Fan Control to reduce the speed manually to 1000rpm. This writes the for 1000 (0fa0) to the smc key F0Mn (minimum speed of fan 0). Applications/smcFanControl.app/Contents/Resources/smc -k F0Mn -w 0fa0 You can and will destroy stuff and I won’t take any responsibility, but here is what worked for me (assuming that you copied smcFanControl to Applications directory): Manipulating the fans could cause overheating and permanent damage. Which could irreversibly damage your computer. This tool will allow you to write values to the SMC From here on you must read the following first: Warning

Its called smc and is also available separately on GitHub. What you need is a utility that is included in the smcFanControl tool. Luckily I found a way around that and reduced the minimum to 1000rpm, which is considerable less noisy! It makes all the difference to me. I downloaded Macs Fan Control, but you can’t reduce rpm below the minimum 1200 (but you can go up to 2700). So the default 1200rpm can be seen as a static value: it doesn’t go above or below that no matter what you do to the system. It seems that on my low spec iMac, the regular (Apple auto-controlled) rpms never get regulated above those 1200rpm, even when running Unreal 3D benchmarks. But then, you hear the fan “idling” at 1200rpm resulting in quite a strong airflow and distracting noise no matter what your system load is. Unbearable in a quiet environment.Īfter installing the SSD, the speed and noise improvement are tremendous. However, apart from the HD being way to slow, it is also very noisy: there is a hiss type of sound and rumble from the rotational mass. Not an easy decision since you need to cut the Mac open. This was after replacing the stock 1TB drive with a WD Green 2TB drive. It is now silent with fans going at around 1200rpm. I somehow got smcfancontrol to work on my 2011 Core i7 iMac. I finally replaced my hard drive in my 2015 iMac 5k with a Samsung 860 SSD. For what its worth, after trying ever fan control application. NOTE: This guide apparently only works up to Catalina and does not work on Big Sur.
