I simply installed mbpfan and within a few seconds, without having to do anything else, all fans went down to roughly 1200 rpm and basically stayed there. Having just swapped out my sons failing 2006 iMac for a 2010 model, I found a previous owner had removed the HDD sensor when they installed a SSD, so the internal fans were all running at full speed, upwards of 6000rpm and they were loud, very very loud. HDD : 1229 RPM (min = 1200 RPM, max = 5900 RPM)ĬPU : 3602 RPM (min = 1200 RPM, max = 3600 RPM)ĮRROR: Can't get value of subfeature temp11_input: I/O errorĬore 0: +49.0☌ (high = +105.0☌, crit = +105.0☌)Ĭore 1: +59.0☌ (high = +105.0☌, crit = +105.0☌)įirst and foremost, I do not run Ubuntu, I run MX Linux, but with MX Linux being Debian compliant and Ubuntu have a similar Debian type base, the same tools should work just fine. Here is the output of sensors if that helps applesmc-isa-0300

Could it be that there is a better driver somewhere that would lead to it heating less? This is happening while browsing internet or even not doing anything, so it's not linked to complex graphics calculations. So: can fancontrol work? if not, do you have any other ideas?Īctually, I realise the problem seem to come from the GPU, since temp1 seems to be in the Radeon PCI section. Also, if it can work, I am unsure what should be the path of each fan to put in that file and whre I could find an example of settings file. But I am not sure this can work, because maybe fancontrol can only control PWM fans and somehow imac fans are not PWM. So I could simply make this settings file myself and set up a min speed of 200 RPM for the CPU fan. Pwmconfig is 'just' a helper to create the fancontrol settings file.

I also tried to install mbpfan: But it is meant for macbooks and not for imacs, with the result that only one sensor seems to be taken into account, then all fan speed are raised simultaneously, which is not helping in my case (see ) What I think could work but not sure how

#Mac hdd fan control how to#

I tried to follow the steps described here: How to control fan speed?, so basically set up lm-sensors, then set up fancontrol with the help of pwmconfig But pwmconfig answers: There are no pwm-capable sensor modules installed Even after adding the module applesmc to /etc/modules and rebooting, no chance. 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.
