    Any thoughts about iMac Pro's cooling performance? Is it enough or not that good? I edit heavy files that Mac Pro 2013 shut down by itself for several times. iMac Pro looks great but I always doubt about iMac series due to its cooling system. Because, as I built custom PC for several times, I can not believe that iMac Pro is cooling both CPU and GPU together with a small cooler instead of using huge coolers. My mac pro is dying and I would need to buy one soon. I would like to hear about iMac Pro's owner before I buy it.

    Mine is completely silent no matter what I do (Lightroom editing/importing/exporting, Xcode project building, video transcoding or even occasional gaming). I just don't hear anything.

    I think this is a single biggest advantage over the regular iMac 5k which is loud when you load GPU.

    I am using the base model (8c, Vega56)

    Similar experience here, 8C Vega64. I can make the fans go up only with the most abusive 3D video benchmarks, and it still keeps up with the heat.

    Don't let this stop you from buying it. There are loads of Youtube reviews that back this up as well.

    I live with 91 year-old who won't turn the air condition on unless it's hotter than HELL! (Joking). The month of May was the hottest month they said and during that time I never heard my iMac Pro fans on my iMac Pro (8-Core). I would take some of the youtube reviews on iMac Pro cooling system with a little grain of salt, for some of them act like they have a masters in thermodynamics. When I used to build my own computers the only was I could get the temps inline was to use noisy fans unless I went with water cooling. Granted I'm sure Apple would had liked to make the cooling system better, but they did a good job considering how enclosed the current iMac is. One side note, I didn't use my computer during the hottest part of the day and basically used it late at night. As with anything a little common sense goes a long way and if I did use the computer during the hottest part of day the air was on even if the old crab didn't like it. :D

    When pushing the GPU, the thermal solution may be effective, but they balanced silence vs performance in gaming wrong. I believe they should spin the fans a little louder to thermal throttle a little less. Just my opinion though. Everything else I do the machine is near-silent, and stays cool.
