What's a healthy SSD temperature in nMP?

[chfilm]

Hey,

I used diskwarrior today for another issue and on a side note, it warned me that the SSD in my nMP was too hot and might fail soon.

It was 65° Celsius.

I'm looking at it now under no load at all, and it has those same 65° all the time, sometimes 62, sometimes 66°.
Is it normal?

Sorry if I come across as paranoid, but I just had a crash on one of my raids, so I can't use another drive failing right now!

Does it say 65 immediately after booting?

I’ll check it in the morning.
Actually I saw before that sometimes it goes as low as 56 degrees.
Then it goes up pretty quickly to 66 with no apparent reason.
I’ll see how it is after booting.

The entire Mac is showing lots of strange behavior since the update to High Sierra, I even had my first kernel panic ever on this machine today after encoding my first HEVC movie file with QuickTime.

Had another one after doing the same thing in media encoder actually!
Both times i was writing to said System ssd.

Also I had the strangest System freezes during my attempts to clone another broken HDD with data rescue, in the midst of it just the entire system hung up, while the HD’s were still working heavily. But the whole screen was frozen on the screen saver. Like the screen saver turned into a still image. not even the cursor was moving anymore...

After bootup the temperature was 33°, 5 minutes later it's at 43°, 10 minutes later 51°...

My nMP is supposed to arrive today. If it does I'll try and check the temperature of the SSD for you.

Cool, thank you!
I tried another tool, DriveDx, and it also got me a temperature warning. I also had another total system freeze in the meantime.
Very weird: The image was frozen, but I could still move the mouse, and it completed a data transfer in the background.

Take a look at the bottom of that screenshot.

Apple Phone support told me to bring it into the store next week -_-
Please tell me your stats nonetheless, I wanna observe it over the next couple of days. I would like to prevent having to bring it in, as I need it as my main source of income when working as a freelancer.

The nMP arrived this afternoon and I just had an opportunity to check the SSD temperature with DriveDx. After sitting idle for over 30 minutes it reported a raw value of 30 (I assume this is in degrees celsius as the program reports but it did say raw values were vendor specific so I can't be certain). I then ran a Handbrake transcode reading and writing to the SSD. It eventually reached a peak of 46.

I am unable to test with Disk Warrior as it appears that is a paid for application.

Thanks! I vacuumed the entire Mac Pro as there had been quite some dust. Now the temperature is at a steady 50 degrees and diskwarrior isn’t complaining anymore. Also had no more kernel panics since. I have an appointment with Apple in one week, so that gives me enough time to observe if the dust was the entire problem or not.

 

[mp2017]

Is the 50 degree reading under load or idle? Also, I have the 256GB drive.

 

[chfilm]

52 degree under absolute idle.
Actually the machine just crashed again, but in the way that it put the screens into power saving mode and didn’t wake back up. Not sure if it had to do with the SSD.

 

[mp2017]

Maybe there's something else generating heat which is increasing the temperature of the SSD. Looks like you need to keep that appointment with Apple.

 

[chfilm]

Yea, if you tell me that your temperature is usually around 30 degrees (try using istat menus to observe it) I definitely should. The Mac is doing absolutely nothing, sitting there with screensaver on and the ssd is at 52 degrees. Everything else is in norm parameters though, according to istat. The fans are silent too. This problem started the hour after I Installed High Sierra! Or at least that was when I recognized the issues first.

 

[mp2017]

SSD temperature of 31 degrees celsius at idle. Any other temperatures you'd like me to check?

 

[MarkJames68]

Dumb question but is this the original SSD with the heatsink? I changed mine out to one from a MBP that didn’t have one so I added GPU heatsinks to the chips.

Well, right now it looks like this, in idle mode:
Anything that sticks out to you?

Yes it is.

A lot does, especially your CPU temperature. Here are the temperatures for mine. Perhaps the ambient temperature is the cause of your higher temperature (seems unlikely).

Hmmm indeed, all your values are lower, it appears that something is causing the overall temperature to be much higher.
What model do you have?
Mine's an 8 core with dual D700.
Thank you so much for your assistance.

Six core, 16GB RAM, D300, 256GB

Mhhm well sure maybe my machine just produces more heat since it has more cores (8), more Ram (64), more intense GPUs (wich are working their asses off with my dual Dell 5k Displays) and the bigger 512 SSD. But maybe something else is wrong... Strange strange strange!

That's a reasonable conclusion. Though I would think the idle temperatures would be more comparable. Perhaps someone with a higher end configuration can provide their measurements.

Though it wouldn't explain why you're receiving high temperature warnings. I would hope that Apple has engineered the system to remain within acceptable limits even in a maximum configuration.
