1 MacBook Pro 2013 15" - Loud fans, hot CPU temps after fan replacement.
Hey ,
I recently purchased a battery and installed it, changed the thermal grease, dusted out the whole thing. Now my CPU temperatures are running around 95C on average, and my fans are on full blast. Happens shortly after booting.
Interestingly, I followed the advice of a friend and powered on the laptop with the battery unplugged, just running from the charger. My CPU temp stayed at like 50C, but it ran super super slow. This was even with full app load.
I reset my SMC, VRAM, et.
I just purchased TG Pro and CoconutBattery, so let me know what screenshots you need!
First image is with the battery in, second is without the battery.

My friend, I think I figured out the problem! I realized that I installed a “Folding protein at home” app a few weeks ago, that I completely forgot I installed! I noticed it in my CPU processes, called “FAHClient”. I then uninstalled it, and now my temps aren’t so bad. How silly of me.
I sometimes get to 90C but that’s under a heavy loud, and once the fans kick in high it seems to tame it.
Screenshots added above!
Это хороший вопрос?

FYI: Disconnecting the battery also looses an import set of thermal sensors from within the battery. SMC needs these sensors to keep your systems temp under control. When the SMC fails to see these signals it goes into Safe Mode, lowering the CPU's clock rate so it doesn't get cooked. I'm not sure I understand why the fans are not running harder, they should be.
Bottomline: It's doing what it was designed to do!

Lets run the onboard diagnostics to see what error pops. Restart your system press the D key, let us know what you get for an error.

Let's follow Apple's directly when you encounter this issue with PPT004 error:
You should first confirm this issue by running Apple Diagnostics over the Internet, which uses the latest diagnostic information. To do this, turn off your Mac by choosing Shut Down from the Apple () menu. Then press the power button to turn on your Mac. Immediately press and hold Option-D until Apple Diagnostics begins.
If running Apple Diagnostics over the Internet confirms the issue
In addition, let's do this install this gem of an app CoconutBattery take a snapshot of the apps main window and post it here so we can see thats happening with the battery and the charger.
Let me know what the internet diags tells you.
