This is not an answer but more a general heads-up.

I recently replaced a fan in a late 2013 Macbook Pro 13in. You may know that this involves removing the heatsink and in turn means that the thermal compound must be replaced when refitting.

I couldn't believe what I saw when I dismantled this machine. The previous (Apple) application of compound was shocking and most of it had squeezed out between the chip and the copper heatsink. The end result was a very poorly applied, uneven layer of material on both surfaces. Also shocking was the scratching found on the contact surface of the heatsink itself after cleaning.

My client bought this machine new direct from Apple. It has not been anywhere for service during his ownership and he said the machine had always run hot. I'm not at all surprised!

The good news is the fan assembly was replaced and thermal compound reapplied to properly prepared surfaces exactly as specified in the iFixit links for this particular model. He now reports that the machine is running cooler than it ever has and is blissfully silent (as it should be).

So I would recommend that every opportunity is taken to routinely replace the thermal compound during any repair - especially where there are associated heat issues. It could well be the case that factory build standards are not what they were and quality control is not picking it up.

Thanks,

Rich :)
