All 4 MacBook Pro Retina CPUs Running at or Around 90-100°C, Continued

This is a continuation of an old question, so I can figure out what is causing my laptop to continually overheat, despite changing the thermal paste several times and the heatsink twice.

Attached are some screenshots of the information that was requested to figure out what the issue is.

Here are the updated photos, as requested. As mentioned, I could not get it into one screenshot.

@danj I hope this helps!

@meeceit - Sadly, there is no context with this info!

Think of it this way... I tore out four pages from a couple of books and paste them here. Now I'm lost! as what are the books?

Then what is happening! Do I have a water damaged book here? What apps or processes are running.

You really need to edit your question with the rest of the story. As you are now claiming four different boards.

All of the context is from the previous topic, which we both have went over. Would you like me to move it over?

There were no other programs running when I took these screenshots. What else would you like me to add?

@meeceit - Please plug this into your original question as that helps!

But! You state you have four different CPU's (logic boards) Or, are you stating all four cores are running? Are they the same or different specs? Did you transfer the drive over?

The snapshots are not ID'ed (System-A, System-B, System-C or System-D)

Also, I don't see a complete listing of one systems sensors and fans. Basically you need to shrink the width and stretch height the window so the right slide disappears then all of the sensors will be caught in one snapshot.

I am not sure how to 'plug' this into the original question, but here is a link to the original question:

All 4 MacBook Pro Retina CPUs Running at or Around 90-100°C?

When I say al four CPU's are running at 100 C, I meant to say all four cores. Same exact machine from the original question I posted a link to above.

How do I 'ID' a snapshot?

I will add a screenshot of everything I can here, right now, all in one, although I am not sure why separate screenshots make a difference. EDIT: I could not get everything into one screenshot, even with resizing everything. I tried stretching the height and shrinking the width, and this is what I got.

Hi, I can see your laptop’s GPU is overheating, as the average temp for that model is between 10° c and 35°c. It is possible that your computer is running like this due to having too many background apps open, try checking to see if there is any background apps by pressing Command + Option + Escape and if there are shut them down and check your GPUs temp.

Thanks, but there are no other applications running in the background. In fact, the temps get to around 100 C from just having my virus protection software running, and the finder - and that's it.

Currently all 4 CPU's run around 50-60 C about 75% of the time if I had to guess. The rest of the time, it gets very hot.

I’m wondering if your issue is the SSD! Looking back at your older question and the fact you’ve hit everything CPU related. The fact your antivirus app pushes it over the top is telling me this maybe a problem with the read/write to the drive. Is the drive overly full?

If you can setup a bootable external Thunderbolt SSD drive which is larger than what you have internally. See if booting up under it does it also reacts the same way.

The drive is not overly full, it is actually almost always empty! It is a 512GB and usually has no more than 50-100 GB on the SSD. Could it still be the SSD?

I have a 1TB Western Digital External SSD that connects via USB, would this work? Also, I assume then I would need to clear that WD SSD, install macOS, and go from there?

MarkyMark tarafından 15 Eki 2021

@meeceit Sure the WD external will work! First clean off anything important on the drive, then reformat it as GUID Journaled file system then just run the OS installer making sure you've select the external drive. Once done reboot and it should now be the top listed on your desktop.

Thanks Dan. I just had another issue with this laptop (I cleaned off lightly with water and paper towels on the keyboard and touchpad area, and unfortunately even after 3 days later, it still doesn't function properly. Did some research and found other people having the same issue, waited the time, put a piece of paper in there (couldn't get much in, but still) so I think this might be time to upgrade.

MarkyMark tarafından 18 Eki 2021

@danj I actually want to try this, but I do not have another SSD right now other than the WD, and it is used for my time machine backup. If there was a way to partition it (is there?), I would definitely back everything up and/or start from scratch, seeing if the internal SSD is the issue.

MarkyMark tarafından 18 Eki 2021

@meeceit - A simple USB thumb drive will do!
