![]() ![]() With my microphone less than a foot away, I don't have any fan noise in my recordings. Like Snell wrote on Six Colors, the fans seem to spin all the time, but Apple has the machine tuned in such a way that they don't really ever speed up the exhaust air just gets a little warmer. Thanks to the 8-core Xeon CPU, it destroys my old iMac when it comes operations like podcast MP3 encoding and running my noise cancellation application, iZotope.Įven under load, this iMac Pro is silent. ![]() It doesn't blow away other iMacs in single-core tasks, but most of what I do is multi-threaded. At $4,999, it is the most expensive computer I have ever owned by a healthy margin, but in the week or so I've had it, I have been very happy with my purchase. So at the very end of the year, I returned my 2017 iMac and walked out of my local Apple Store with the standard configuration iMac Pro. I found myself popping into Activity Monitor to find some system process using 50% of the CPU, making the fan spin up. I needed a computer that would only be loud when I pushed the CPU the 2017 would spin its fan up with no obvious reason. I felt as if I couldn't trust the machine to stay quiet when I was recording podcasts or shooting video in my small studio. When HandBrake was running at full speed, the iMac Pro sounded pretty much the same-but the air coming out of the vents on the back was definitely warmer! In my normal office environment, I can't hear it-only when I spun the iMac Pro around and listened with all other devices off could I hear it, faintly blowing. So far as I can tell, the iMac Pro's fan may always be running, but it's amazingly quiet. ![]() When running HandBrake, the fan on my 5K iMac would always crank up and was quite audible when it did so. I was thinking about this, wondering if I should return the 2017 iMac when I read Jason Snell's first impressions of his entry-level iMac Pro:
