    I have an iMac Pro with 64 RAM and it is still in the return window. I'm wondering if I should consider ditching it for a i9 8 core 2019 iMac with similar specs and save about $1400 (by adding my own RAM from OWC). I have not seen any conclusive breakdowns saying if the new iMac i9 is having any excessive fan noise like the 2017 models when under stress, although I have seen some posts saying that people were hearing more fan noise at idle. I've seen videos showing that there is no throttling, but they can run hot. I use the iMac mainly for audio production so noise is a consideration but, for a difference of $1400, maybe I can tolerate a little noise once in a while? ASLO, sometimes when I record vocals, I have to turn off the AC and the ambient air temp can go up, causing the fans to come on... especially in the summer. Are the iMac pro's cooling system and T2 chip, etc really worth the price difference? Thanks!

    I was pondering a similar quandary, but for a different reason. I went back and forth between a refurb iMac Pro and a 2019 iMac before finally ordering an i9 8-core. Before it could even be shipped I found out that I can’t boot a 2019 iMac into High Sierra if needed while I could with the iMac Pro. So, I debated whether to cancel my order and go back to the iMac Pro, but the price differential made it not worth it to me. The i9 iMac with 1TB SSD with Applecare was $3188 out the door, plus $200 for 32GB RAM for a total of 40GB for $3388. The refurb iMac Pro would have been $4854 for the 32GB base unit. $1500 was not worth it to me when I can just run the old OS in Parallels for $63 if I needed High Sierra.

    Wow! Didn't know about being able to boot to High Sierra. Thats cool! The price difference is very substantial but boy this iMac Pro runs cool. Decisions!

    both have some small pros cons
    from one I read is the pro has dual thunderbolt bus where the regulars have one ? so that could be a issue if you had multiple devices that require that ?

    otherwise I reckon I would go for the iMac i9 9900 and put the coin into something else

    Jason Snell reported that his base iMac Pro is fairly quieter than the top-spec iMac he was loaned by Apple for evaluation. While the 2019 iMac does not ramp it's fans as quickly as the 2017, it will still spin them much faster than the iMac Pro when both are under "full load" and therefore the iMac will be noticeably louder at in such situations.

    good to know :)
    I have never owned a iMac but looking now and wonder if even when so called loud what they are like compared to the older mac pro like the 5,1 ?

    for some reason the sound of my old G5 tower came into my head and was saying WHAT I CANT HEAR YOU :) if you ever had a silver towered G5 you would know what fan noise can be :) hahahhahahahah

    The maximum fan RPM for the iMacs is 2700RPM. It was quite noticeable to me on the 2015 model and a bit less so on my 2017. I am told it is less noticeable on the 2019 than the 2017.

    Not sure what the maximum RPM is on the iMac Pro is, but all the owners who have commented have said even when they "fully load it", they cannot hear the fans and have to put their hands or a piece of paper next to the fan exhaust to notice the breeze.

    I'll be interested to hear this famously quiet iMac Pro. My boss is in the process of ordering me one at work, so if it's approved I'll be able to test both. I have the i9 iMac at home and it seems pretty freaking quiet to me, but it's also pretty cool in my basement studio area. The top-end i7 2017 iMac I had at my old job was pretty loud a lot of the time, and that was also in a relatively cool basement.

    If I had more budget, I'd have gotten the iMac Pro for use at home, even though the CPU is a little slower. I'd prefer a faster GPU and the space gray look. But you can't beat the i9 5K iMac on price/performance ratio as it's among the fastest Macs you can buy.

    I have a i9 iMac here and am returning to keep my Late 2015 with 4.0 ghz i7. The 2019 seems every bit as noisy when rendering video and was could even be heard more when idling or simply importing video from flash drives. To me it was not quieter in any way. Also, my IR gun was reading 20 degrees Fahrenheit higher temps on the back near the fan. It ain't cooler either, it's hotter. I'll wait for a cooler running redesign. I'll like my 2015 even more now after sampling the 2019.

    Don’t worry, you won’t. :D

    Actually, I heard mine for the first time yesterday. I was helping someone troubleshoot a system and ran the hardware test on mine (hold the D key while booting)— didn’t know if it worked the same in Mojave (it does). Among the many tests, the fans come on for about 5 seconds. So that’s what they sound like... Interestingly, the progress bar stated the test would take 4minutes but took about a minute to complete.

    The iMac Pro is an incredible machine for audio production.

    The 2019 iMac 5K isn't bad but I finally heard mine ramp up to full speed for a long period the other day. I was doing a large ingest of 42MP RAW files into Lightroom and it was having to generate a thousand or so smart previews while doing image analysis for facial recognition and things like that while uploading the smart previews to Creative Cloud in the background to sync to my iPad. So it was kinda annoying but not something I can't deal with every once in a while.

    Keep in mind that an 27 inch iMac 5K, 2015 to 2019 (doesn’t matter what year) holds a value around 1400€ on the used market while an iMac Pro is still worth around 4000€. So if you’re planning to sell it within 6 six years the iMac definitely has a steeper write off. It’s thermal system also isn’t optimized as well as the Pro.

    As I’ve said before, I hope you get your Pro at work. You will be in the unique position of actually knowing the difference based on ... what’s that word? ... oh yea, experience.

    Yeah they were fighting my boss on it the other day but that’s based on being classified as a web designer and developer when in reality I already do so much more than that and it will be expanding even further with video production. She’s fighting back now but I may just end up getting a similar system to the one I have at home, which wouldn’t be bad. We’ll see but I’m not as hopeful as I was at the outset.

    I have decided to keep the iMac Pro. Yes its more expensive but after having had it for a couple of weeks it just never breaks a sweat. Its whisper quit and has a certain mojo. Maybe Apple has it figured out and didn't screw the iMac Pro owners with the release of the iMac with i9 after all? I am sure the i9 kicks butt but the extra fan noise may be a deterrent... or not. The new cooling design of the iMac Pro won me over.
