The CPU temperature will also stay in this healthy temperature range.ĭownload Macs Fan Control on the dev’s website, on github, or from my local mirror (v4.1.12). So since we need to make sure the PSU does not overheat and melt your display panels LED strips on the right side, we set the CPU fan speed in relation to the PSU temperature. I learned that Apple did decide to „cool“ the PSU by blowing the CPUs hot air onto it. By removing the control board from your old hard drive, you can trick the iMac into thinking a new hard drive is compatible, keeping it from turning the fan on. Set the CPU fan to be controlled by the PSU Primary temperature. This stuff is sitting in the middle of the iMac case.
