This do lower the temp of these 2 sensors, until aournd 80C, 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. He did admit though that he couldn't hear the iMac fan "over the sound of their air conditioning system" - so it must be alright anyway, right? 😢 Basically, 2 sensors, TD0D and temp1 see an increase in temperature until reaching 105C, which triggers the increase of the CPU fan speed. 🙂 The Apple engineer subsequently phoned me at home, saying he had reinstalled the software, ran through the standard checks etc - but again had found no issues.

Default values are usually 100 which will make the CPUs 'turbo mode' kick in quite often which usually makes the fans go crazy.
Ran through all the checks over the phone with Apple Support and no hardware issues detected.
Ended up talking to Apple Support who confirmed that the iMac fan noise should not be detectable - when the iMac is effectively idle.
