So my 16-core just arrived and my personal feelings are that Apple is a bit more conservative on the fan control. 3D rendering temps were getting into the 90˚ C on the CPU, so I decided to get TG Pro and have it control the fans; more fan noise but now sitting good at 70˚ C.

I will say though that the machine is pretty much silent with Apple's default fan control.

What do you guys that also have the new Mac Pro think? Of course (I am assuming everyone got AppleCare) AppleCare would hopefully cover anything that would happen.

I am kind of surprised that the fans pretty much stay at 500 RPM no matter what you do having OS X or T2 or whatever is controlling the fans do it. Feel much better letting TG Pro do it ($10 is nothing)
 
Did some more research and perhaps someone can shed better light.

So the average CPU temp is around 54˚ C cranking. CPU PECI is at 70˚- 95˚ C cranking. What I find odd is that according to Wiki, the PECI temp should be a negative number; but that isn't how it is being reported by TG Pro.

I have gone back to the system controlling the fans.
 
I havent heard anything about fan problems, but have heard from multiple users that the CPUs are not hitting the advertised speeds, especially turbo boost speeds
 
Yes Intel Power Gadget confirms that on mine when it is cranking all cores. It does hit Max Turbo if I am doing something that does not pound all the cores at once.

With all cores cranking the average says around 3.1 Ghz. Using about 190 Watts.

I am not implying there are any fan problems. Just trying to read what I am seeing correctly.

Same observation here. I was using it for data processing using only 9 cores (out of 12 cores) and fans did not kick in any higher than default 500 RPM even after reaching closer to 90ºC.

I configured TG to run at 950-1000 RPM to bring the temps to upper 70ºC. I am not very excited to keep my CPU running more than 75ºC. I wonder how does this machine fare after long term use with high CPU usage.

I fail to see how you would be surprised, Apple has done this for decades. They prefer a hot machine over a noisy one the threads are countless in number about this including yours again today and others soon be started ...

I went back to TG control. I find it interesting that none of the bloggers seemed to bring this up. Yeah I knew it was going to run hot, but jeez, not that hot.
 
Perhaps this video will give you some more information?


Don't know enough about this temperature stuff myself but maybe it helps.
 
Cool. Thanks. I watched that already; and although semi useful. He does not mention if his room is a fridge or not. Would be good to know what the ambient room temp was.

Yeah , its an Apple tradition to let components get hotter than they should in order to keep the System quieter . System fans have been known to make a lot of noise . Unfortunately , this also means a lot of Apple products are subject to thermal throttling . Steve Jobs was probably responsible for this situation becoming embedded in Apple's subconscious corporate DNA , to continue after he passed away from us . He was said to have sensitive hearing .

But off all Apple products, you'd expect this to be the quiet AND cool one :rolleyes:
 
Thanks for sharing our video.

500RPM is basically idle for this machine (the fans never turn off). On Macbook it idles at 1800RPM.

intel states that there isn’t any issue for the CPU to be running hot constantly and if it’s too hot it will automatically slow down (I think at 95C)

Macbooks will run at that temp constantly with fans at full blast of your maxing our all 8 cores.

You can definitely use TG fan pro to set your own fan speeds if you want it to run cooler but I wouldn’t worry about it personally.

As for turbo boost speeds 4.4 is only if your using either 1 or 2 cores. All cores have been lower for a while. It’s intels marketing.

Heck, they go even crazier on consumer chips. The top i9 is rated for 5ghz which the 16” can sometimes hit but the 15.4 never could because that number is only reachable if the your using a single core task and if the temps are below 50C which never happened in real use.

I don’t think my 12 core hits higher than 85C long term with the fans idling but I will test it later.

Our results for Medium lengths tests are in that video.

One of the concerns to keep in mind is System durability . If all the components are kept cooler during normal workflow practices , the System will last longer before some serious issues occur . This is not something measured in 2 or 5 minute benchmarks . A decently made and maintained open architecture workstation will stay online for some 3 to 5 years . And even then , repaired economically . The compute GPUs , from System Building experience , are the first major component to go offline . There's a reason why bitcoin miners sell their GPUs around 2.5 to 3 years after first deployed . They don't want to rebuild a whole farm of graphics cards before they crap out ( preventative maintenance ) .

Wow! Thanks for chiming in Max! I have the 16 core so it stands to reason that it probably gets bit warmer than the 12 core. Can you let us know about what the room temps were when you shot the video?

I am personally ok with the fan noise if they run around 1000RPM; which keeps the PECI Temps around 70˚ C going full on; the proximity sensors around the CPU stay in the 50˚ C range. CPU Freq stays around 3-3.2 Ghz.

I ran the machine for about 24 hours straight doing a LW render. Had to it today, since I am cleaning up the wiring to my monitor (so I can switch between all 3 machines). Fun times ahead!

the video is amateurish
running cinebench a few times with breaks in between is not the same as rendering at full load for 30mins+

what is your experience when rendering 24 hours?
how was the fan noise after 30mins?

Fans stayed around 1000rpm (modified setting using ap) running 2.5 days straight. Lightwave 3D render. All cores tapped. 3.3 GHz average clock. 16 core model.

what is "ap" ? and... it means you altered the fan curve because the default was too loud for you?
and those 1000rpm would you describe? noticably but ok to work with, when the pro is under the table?
 
No default it stays at 500-600 rpm and I felt the PECI was getting too hot; around 90 degrees C.

Yes I used an application to alter the fan curves. Still quiet at 1000rpm. PECI stays around 70 degrees C.

ok thanks, that is interesting and good info.
while my TR is a lot faster to render, the fan noise is not "mac like" at all :)
but it seems apple simply accepts very high temperatures

also my mac pro 2012 renders with very high temps, close to 90C
i noticed that now, after years of working with it

maybe these temps actually do not matter that much
apple would not do it if the pros would break after 2-3 years
altough.. they can always change the behaviour by software updates

Did you noticed heat emanating in the room during CPU intensive tasks? I'm thinking on buying a 16-core Mac Pro but I am worried about my room being filled with warm air
 
Of course the room is going to heat up. It isn't more than any other high core count CPU though.

I am also considering a 18-core iMac Pro. Do you have any experience with that?

You can heat a decent size room with an iMac Pro. We left one running overnight in the shop and it was pretty warm in the room when we came back the next morning. Smallish at 9x12 or so but still.
 
I would never buy a iMac because it is an all-in-one. Monitors last a long longer than computer guts.
