In the late-2011 model, is TB0T actually in the battery?
Which of these sensors should I trust? The last 2 vary extremely little so Im not sure. The TB0T is the only one that actually seems to sensibly rise and fall with charging.
Temperature
DESCRIPTION KEY VALUE
Battery 1 TB0T 47.5 °C
Battery 2 TB1T 24.6 °C
Battery 3 TB2T 24.6 °C

Where are you reading these values?
I find CoconutBattery offers a better view of things and more trustworthy than some of the other monitoring apps.
Can you take a Snapshot of the Apps main window posting it here so we can see things as well. If you want to get deeper into the thermals I do recommend using TG Pro
I think between the two you’ll get more that you need to see what’s happening.

There is more to life than Coconuts and TG Pro sir.
However yes I see that Coconut Battery's temp value corresponds with TB0T, so that's the one I'm going with.
They're standard SMC keys. iSMC is a nice console app that can read them. Or Chris911/iStats.
Too bad the schematic pdfs don't clearly tell you which ones are which, beyond names like T29THMSNS_D2_P or whatever.
@breathlungs - I didn’t say there wasn’t other options for tools, over the years I have found both of these very reliable and easy to digest the data from when working with people remotely. I’ve been repairing these systems a very long time.
As to poking around the SMC values directly, from a diagnostic perspective it’s not needed. I can see someone diving into the values who is trying to reverse engineering what Apple did to create custom diagnostic tools or to enhance the system in some way. That’s outside of what we do here. Even board level repair doesn’t need to get into the SMC logic only that the inputs are correct or replace the chip if the values are correct.

Are you sure you have a MacBook or do you have a MacBook Pro? They are different.

@danj Oh sorry it's actually the MacBookPro8,1
