5K iMac vs. iMac Pro: The pro’s silent fans made a fan out of me

“Last month, we left our hero weighing his options, considering replacing his i5 Late 2015 iMac with 5K Retina display with an iMac Pro,” Stephen Hackett writes for iMore. “After I wrote that column, Apple released final pricing details on the iMac Pro, so I sat down with my budget, a spreadsheet, and Apple.com loaded in my browser.”

“I knew the $4,999 entry model was the only iMac Pro I could both justify and afford,” Hackett writes. “The standard iMac Pro is still a lot faster than my 2015 could ever be, but then I started looking at a fully loaded 2017 5K iMac. If I opted for third-party RAM, I could pick up a 4.2GHz i7 iMac with a 1TB SSD for $3,099. With this iMac, I would still have a noticeably faster machine on my desk, but with a lot more cash in the bank.

“I decided to take the conservative route, so I ordered the regular iMac. It showed up the day after Christmas. I slapped 32GB of OWC RAM in it — for a total of 40GB — and migrated my data from my trusty 2015 model,” Hackett writes. “Unfortunately, it didn’t take long to realize that I had made a mistake. Even during the migration, I could hear the new iMac’s fan blowing, and once I was logged in, it was even louder.”

  1. Oh…the iMac Pro is not quiet when you get all cores running, and the heat blowing at the back is definitely not comfortable It’s actually a lot warmer than the MacPro with the same load.

  2. Ok, it’s more quiet than the 5k iMac, but it is also almost twice as expensive, depending on configuration. To me, fan noise is not much of an issue because I don’t deal much with sound recording. But I could see how this could be very important for some folks.

    1. You do not have to be recording to appreciate a quite machine that is in your face. A workstation is usually nearby but not on top of you but the all in one form factor put the fans, intake and output all at or near eye level.

      Having had any number of Mac Pros and PowerMacs, I assure you when the load gets high enough the fans will become noticeable. The Cheesegraters were the quietest I have ever seen or used at home or work- lots of fans, plenty of internal space to circulate, high heat sink, thermal zones to isolate the CPU and power supply from the rest.

  3. I’ve had an iMac 5K with an i7 CPU since it was introduced in December 2014. I use it every day and I have never, ever heard its fan. I normally have at least 5 apps running. In fact, I thought it didn’t have a fan, but cooled using convection. I guess you learn something every day. I have another 2012 27″ iMac that my wife uses, also with an I& CPU and have never heard its fan either.
