iMac FanControl with Linux: Simple Steps to Follow

Well, today I messed around with my old iMac and tried to get the fans under control using Linux. It was a bit of a hassle, but I figured it out in the end, so I thought I’d share my experience with you all.

First off, I had this old iMac lying around and I decided to install Linux on it. Everything was running fine, but the fans were going crazy, making a ton of noise. I knew I had to do something about it.

I started by searching the web for answers. I found out that on macOS, there are tools to control fan speeds and stuff, but for Linux, it seemed a bit trickier. I stumbled upon some stuff about “fancontrol” and “lm-sensors”, and something called “applesmc”. It all sounded like a foreign language, but I was determined to fix this.

I installed a few packages using the package manager. I remember typing things like sudo apt-get install lm-sensors fancontrol and hoping for the best. After installing these, I had to configure something called sensors-detect. It asked me a bunch of questions, and honestly, I just kept pressing “yes” to everything. I mean, who reads all that stuff, right?

Next, I ran pwmconfig. This was supposed to test and configure the fans. It detected my fans and asked me to set up intervals and temperatures. I played around with the settings, not really knowing what I was doing, but I managed to get through it.

• Install lm-sensors and fancontrol: This is where it all began. These tools are essential for monitoring and controlling the fans.
• Run sensors-detect: This step is crucial to help the system detect the hardware sensors.
• Run pwmconfig: This utility helps in configuring the fan control settings.

After all that, I had to edit the /etc/fancontrol file. I put in some values based on what pwmconfig told me. I tweaked the minimum and maximum fan speeds and set the temperature thresholds. It was a bit of trial and error, to be honest. I messed up a few times and had to reboot the machine more times than I’d like to admit.

Finally, I started the fancontrol service using sudo systemctl start fancontrol. And guess what? It worked! The fans calmed down, and the iMac was running much quieter. I felt like a genius, even though I barely knew what I was doing.

So, there you have it. That’s how I managed to control the fans on my iMac running Linux. It was a pain in the neck, but I learned a lot. And hey, if I can do it, anyone can. Just be prepared to mess up a few times and reboot a lot. Trust me, it’s worth it in the end.
