1) Questions and Answers : Macintosh : I7 Fans (Message 56710) Posted 20 Aug 2017 by R M Wilson Post: I was running WAH2 on my i5 mid 2010 iMac with 12 Gb RAM. Using 100% of the CPUs at 85% of the time gave me a relatively hot but quiet iMac. I have recently purchased a 2017 i7 iMac with 48Gb RAM and although the computer is quite cool to the touch the fan (s) are really giving it some welly. I have now reduced usage to 50% of CPUs and 50% of CPU time. Why, on a more advanced machine with greater specs is this happening. I have spoken with Apple support and they are at a loss and recommend taking the machine to the local Apple Genius Bar for testing which, of course I'm loath to do until I get a reply from your good selves. I look forward to your reply, Mike Wilson Bangor, Co. Down, UK
