Fan not cooling system when CPU temp rises

Hi,

I have a similar issue with a Late 2012 MacBook Pro Retina. Fans will not compensate for rises in CPU Temperatures so it would shut down.

I have tried to search high and low for answers and I don’t think it is the Ethernet via thunderbolt chip issue that the 2013 models have.

This is a sensor issue that I have managed to control using TG Pro and Auto Boost.

My question is: Can whatever chip be replaced that controls this without resorting to software. I’m trying to sell this Mac and cannot if it has an issue and have to tell the buyer that they need to install TG Pro to keep it from shutting down.

The first thing I would do is run the onboard diagnostics to see if any errors popped.

I would like to see a resting system's TG Pro output and a second when the system is under stress without over-riding the fans. Make sure we get all of the sensors in the snapshot as I need to see a few of the ones at the bottom of the list as well as the fan. Post both here so I can see what you have iFixitでの質問に画像を追加する方法.
