Click on the process and then click on the X above to stop it. If you see any apps that are not essential, you can close them to see if that stops the fans. To see which apps are taking up the most CPU, open Activity Monitor, click on the CPU tab.

Therefore, you should reduce the number of apps that your Mac is running in order to prevent your fan from getting too hot. If overheating persists for a long time, your Mac’s fan may even reach its limits and make some loud noises.

In this case, your MacBook’s fan will have to run constantly at a high speed. The more apps and browsers you leave running at the same time, the more likely that the device will overheat.

If your MacBook Pro fan is loud most of the time, it may indicate it’s running faster than it should be, or there is something triggering it to do this. If a restart doesn’t work, try resetting the SMC and PRAM.If the fan is continually running at a high speed, try a Restart. It’s one of the biggest causes of CPU/GPU stress, and will no doubt increase your MacBook Pro fan speed because Flash is so intensive on hardware. In Chrome, you can use Flashcontrol to disable instances of Flash (it still allows you to view Flash on a per-site basis as needed). Flash is now disabled by default in Firefox. Apps like Photoshop, Final Cut Pro, and VMware Fusion/Parallels tend to cause the fans to speed up, as the temperature of your CPU/GPU will increase when using those apps. You can also see which apps are using the most energy as well. Open “Activity Monitor” to see which apps are using the most CPU. Disconnect devices that require heavy GPU use.

If it is running at maximum RPM (usually about 6000 on a MacBook Pro), this indicates there is software running on your Mac that is stressing the CPU or GPU. However, it should not be excessively noisy or running at a high speed all the time. MacBook Pro Fan Always OnĪ MacBook Pro fan should always be on. Applications/smcFanControl.If your MacBook Pro fan noise is bothering you, it’s always on, loud, not working, or experiencing other problems like invariable fan speed, or excessive noise, then there may be several things you can try to fix. 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. I finally replaced my hard drive in my 2015 iMac 5k with a Samsung 860 SSD. NOTE: This guide apparently only works up to Catalina and does not work on Big Sur.
