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 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. Macs Fan Control is an excellent tool that's easy to install on your Mac and is particularly useful if you want total control over your system fans.I switched an old Imac (2008) to Lubuntu. This useful program can potentially save your computer from overheating and melting down. You should note you can also set certain values so that the fans on your Mac always revolve at a certain speed or increase their activity if the processor temperature is too high. Plus, via the interface, you gain individual indicators including the number of revolutions per minute for each fan and the exact temperature the blades are. This is very useful when you want to check or detect any possible anomalies or malfunctioning in one of these parts. Through Macs Fan Control you get to see each fan that's inside your Mac. Through a simple interface, you get the option to control the most relevant characteristics for each part in order to ensure the proper functioning of your PC. Macs Fan Control is a program for Mac that allows you to gain full control over your Mac's speed and temperature as controlled by its internal cooling system: its fans.
