Resolved 16’’ hot core temperatures

[Codeline]

I have no idea if this is normal so thought I would ask the educated in here.
The CPU core 8 is rather hot at 129º.

I thought the cores would all be roughly the same temperature give or take a few degrees but sitting this high.

is this ok and normal?

What’s the software? It could be a bug. Have you verified it with any other status monitoring apps like iStat Menus?

could it be a hotspot on the die?

It’s a HWSensors monitor, i have tried it on a 15’’ 2015 MBP and its running as i would expect.
On a 2019 15’’ its the same 129º...... strange! Must be software.
Is the istat a good monitor app?

Definitely a bug, Intel would force a shutdown if a core was really at 130 degree Celsius.

You can get detailed CPU (and other hardware) usage with the sudo powermetrics command. As it requires root permission I recommend looking it up before running it so you know for yourself you're not doing anything you wouldn't want to do. I don't believe, if I remember correctly, that it gives you individual core temperature but it does give you per-core load and per-core interrupts. If you had some core that was much hotter than the others you would see that reflected in the load information.

It’s one of the most popular for macOS and is worth checking out, yes. As its name implies: it runs in the menu bar. I disliked some aspects of the UI a few years ago, but maybe they’ve fixed that now?

That is an impossible value and will be either a software bug or a defective hardware sensor.

I found the problem with the crazy Core 8 temperature.... I downloaded istat, great monitor.
Reason for the high temp........I only have a 6 core mac.......

well at least i owned up to my stupidity
