This is annoying because I think with a fix speed set to 2000 RPM for example, the temp would stabilise at an acceptable temperature, hopefully below 90☌, while the noise would still be acceptable. This do lower the temp of these 2 sensors, until aournd 80☌, but this is not cool enough to reduce the fan speed. This fan gradually accelerate until its max, 3600 RPM, which makes the imac very loud. Here is a screenshot of psensor: psensor screenshotīasically, 2 sensors, TD0D and temp1 see an increase in temperature until reaching 105☌, which triggers the increase of the CPU fan speed.


While it runs smoothly for all I need to do, 20 minutes after starting the CPU fan starts to get super loud. I switched an old Imac (2008) to Lubuntu.
