MP 7,1 NORMAL for Mac Pro 2019 fans to spin in sleep ?

[2bcool2]

It is clear that at 12:14:17 your Mac has been woken by something ('com.apple.message.waketime: Dark Wake from normal sleep').
I don't suggest that this is 'normal' as a whole, but it is likely to be a 'normal' cause and effect situation. i.e. something has happened that called for the Mac to wake, and it did.

Now that that has been established, you could try this command in Terminal:

log show --style syslog | fgrep "Wake reason"

When you press Enter, nothing will happen for a few seconds, then the log will display.
This should give a better clue as to what the cause was.

By the way, in the meantime (sorry if I am repeating previous suggestions):
- Do you have 'Wake for network access' switched on? In that case the Mac would wake "At regular intervals so that your Mac can notify other computers on the network that its resources are available."
- Also, enhanced notification will wake your Mac. To disable this you should turn on 'Do not disturb'.
- One of your USB devices could send a wake signal. Have you tried unplugging them?
- Bluetooth can send a wake signal. Have you tried switching off either Bluetooth on the Mac, or all the Bluetooth devices?
- Obviously I assume Power-Nap is already Off.

the command gave this :

I don’t think a majority of us not hearing our fans suffer from hearing loss.

Unless we all live in the same house with the same conditions?

I think a lot of us are fortunate to have the Mac in an idea condition for it not to operate harder than those experiencing having to hear it operate with more effort.

ahhh thanks this is interesting .. I did ask apple about this but they said 24C is not a bad room temperature, it’s fine. Reinstalling the macOS and testing the Mac clean with no apps is a great idea. If you have a Time Machine backup, and can add the programs back one at time that too may help narrow down if it was coming from a software program.

well yes could be some people have a controlled temperature room .. we will see in the winter if the fans are silent or same as now... the fan volume isn't really a problem just a curiosity .. but having the Mac Pro in the bedroom and coming on when they shouldn't is a problem I need to fix.

 

[Wando64]

so its been 2 hours 35 and with only the power plugged in , not even the monitor .. the fans dont come on .
in a bit I will try your terminal command.

could it be something to do with the w5700x and my lg monitor via thunderbolt ? could it still be the OS ?
like I said I did ask apple twitter but they aren't talking anymore .. I will call apple but long hold times

thanks

If the fans didn't come on, probably the Mac didn't wake so the Terminal command will not reveal anything useful in relation to this last try, but should still tell you about the previous events.

yep, pretty sure its gonna happen again , coz I haven't loaded any apps on this test. so its been 3 hours and no fans on , factory setting OS apart from all ticked off in energy saving etc .. I plugged the monitor in the top thunderbolt port instead of the w5700x for a change and no internet connected .. so next ill try downloading Davinci free and see if adding an app changes things ..

It looks like your Mac is being awaken by the Lan (Ethernet or wireless). This shouldn't happen if you have wake on Lan switched off.
Also it has woken to respond to some Bluetooth and Tunderbolt devices.
This should help your troubleshooting, however IMO this chase is not very useful as the Mac is doing what Apple has decided best for it to do.
If you are really disturbed by the fans, you might want to consider switching it off.

for a week I have been switching it off.. but its such a pain .. I just want the same function as a cheap iMac .. sleep , no fans. it says AppleACPIPlatformPower Wake reason: EC.Bluetooth (Maintenance)

does that mean something bluetooth might wake it ? but its dead on 2 hours everytime.

when it was asleep , I plugged in a thunderbolt and the fans came on , no picture etc as usual ..

I thought maybe I can fix it with some help here, but might have wait for a call from apple .. apple help on twitter has been no help lol

 

[Wando64]

By the way, in the advanced Bluetooth setting you can disable wake on bluetooth, but this means that your bluetooth keyboard and/or mouse will not be able to wake the Mac.

yup unticked all 3

I was gonna try turn off bluetooth next and try wired kbd and mouse

From your log:
at 10:14 it was waken by the network,
at 12:15 it was woken by Bluetooth,
at 12:43 it was woken by Thunderbolt.

So it looks as if at this point your settings are still allowing all of these methods for waking your Mac.
You might want to ask Apple why the network can wake up your Mac when you have deselected the "wake from network" setting. And same for Bluetooth.
I am not sure you can disable wake from Thunderbolt.

thanks I will ask. when its asleep I won't be plugging any thunderbolt in anyway , downloaded davinci so now will see if loading an app makes it awake in the next couple hours..


could you imagine how much easier it would be if the fans were coming on after 10 mins lol ...

so just a little update,

after thefts not coming on with the monitor thunderbolt plunged into the top I/o instead of w5700x and no net plugged in , no dropbox active, no Apple ID active , safari closed down .. I loaded my backup with all my apps on and put it to sleep and it didn't wake up all night.

so I wonder if its dropbox app or appleid or ethernet connected or monitor plugged into w5700x that may be part of the problem ?
I will try opening safari and connecting the ethernet to the net and see today. it shows that the fans shouldn't be coming on

as for :

at 10:14 it was waken by the network,
at 12:15 it was woken by Bluetooth,
at 12:43 it was woken by Thunderbolt.

I put it to sleep at that time at 10:15, fans came on at 12:15.
12:45 I put it to sleep but plugged athnderbolt in and the fans cam on so woke it and re sleep it at 12:45 and the fans cam on at 2:45.

but that was earlier in the day, the evening tests had no fans ..

The fans don't necessarily have to spin every time the Mac wakes for something.
It might wake for a few seconds, do what it has to do and go back to sleep very quickly.

 

[OkiRun]

I ask two editors to put ear next to the 7,1 and say if they hear the fans. Both say no. And I say can't hear it and it has FCPX open. So can't hear with ear next to front of computer. And can't hear with on the floor and sitting in chair with edits. Something is completely different with our machine and those machine with lots of noise. Don't know if fans turn on and off every hour or two as don't hear the fans; never. Wish I could test something for you to compare and explain issue. Good luck.

yes , if the fans came on fr 2 mins that would be fine .. but they stay on past half hour .. I got bored timing after that lol

yes its weird.. I think it could be the temp of the room, maybe your surroundings are temp controlled ( I guess ill know in the winter ) its not really a problem, they are not hugely loud, and after the jet engine of the old Mac Pro grater, they seem fine. but in a bedroom and they come on and stay on after two hours is not good for a premium machine.. I know I can shut it down , but why have sleep mode if it doesn't properly sleep.. my aim is to find out the problem now , and if its not solvable .. well ill live wit having to turn it off every time. will post the result here when I find it lol
many thanks

 

[2bcool2]

so all I did for this next test was connect to the net via ethernet and open safari and the fans came on 2 hours later.

I wonder if its the ethernet or just safari waking it .. I will try no net , just safari. but in earlier tests last week, I tried with no ethernet connected and it still had fans come on ..

Although I'm one of the people who experience no strong fan operation and therefore no loud fan noise whereby I can't hear it within 5ft from ear to machine with regular fan operation. However I can definitely hear the fans if I place my ear by the front case. It's not evident and is very light and pleasing, but it's not NOT discernible.

I guess it depends the kind of GPU being used as well apart from the actual ambient conditions on how fast (and loud) these spin to be apparent.

would the (apple) GPU type count when there is no processing going on ? simply starting up the machine ?
I can hear the fans soon as it starts up .. but again I dont know if they get louder your room is hot .. apple said 24c is not hot for them .. ive had two units and both have same level of fan noise ..

 

[LeonPro]

It's still doing work especially depending on the monitor(s) connected to it. 24C isn't hot. My room can get warmer right now at the peak of Summer.

Can you take a photo of your Mac Pro location and/or record the fan noise for us to hear based on the distance you say you hear it from?

sure here's a quick vid I took, not sure if the camera picks up the noise well, the room is silent, that you hear is the clock and the fans.

last nights test had it slept all night, no ethernet connected, safari open, Apple ID connected (just in case its that that's trying to call home )

so if I left it like this and when sleeping pulled out the ethernet cable .. it wouldn't wake so far.
I may try connecting via wifi, then turning wifi off then sleep ( still no ethernet connected) and see.
I have a feeling if I connect some thunderbolt ports up and sleep it , it might wake up ..just a feeling.

 

[LeonPro]

I'm not sure if I'm hearing it correctly, but I do hear two things - the clock and a constant white noise in the background. I was expecting to hear a faint and pleasant "whoosh" sound, but if that white noise is your fan then that's definitely not what I'm hearing with mine.

I think its hard to record the sound accurately. it is a whooshing sound and its fine.. I was just curious how somany people say its silent and cant hear it. it is right on my desk though .. anyway.

so second day and no fans come on in sleep. I've signed into Apple ID , added more programmes and when sleepit I pull the ethernet cord out. maybe that's what's waking it .. but I did try this a week ago with just factory OS no added apps and unplugged the ethernet cord and still it came on after 2 hours ..

I'm just happy so far its doing fine.. I haven't restarted ut or shut it down since and I wonder when I do if that willl cause it to wake up again after 2 hours of sleep...

I also don't know that if I leave a thunderbolt ssd plugged in when sleep if that will also cause it to wake.

cheers

 

[2bcool2]

so
wouldn't you know it... sleep has been fine for a day or two .. now today I do the same unplug the ethernet, sleep and turn off monitor, but I come back two half hours later and the fans are on ! .. I did nothing different!!

here's the console read out sleep at 9: 10. wake at 11:11.

I have no idea what's happening ? why 2 hours ???

i hope you have switched OFF power nap in the energy saver systemprefs!
