  The commenter I responded to specifically claimed: > Remember that time about 15 years ago when MacBook Pros were all overheating and the root cause was Apple was adding 10x the amount of thermal paste needed at the factory? Many people saw the images from the repair (oh, I'm sorry, service) manuals and directly claimed that was how systems were being prepared in the factory. > Apple used to produce detailed service manuals in English: I'm aware of that. The factory does not use repair (or "service") manuals, and they would not be written in English. > More on the overheating issue That post does not show a Macbook Pro, does not show over-application of thermal paste from the factory, and does not contain any evidence of impacted thermals. Further, it claims: "anything more is overkill and can hinder the cooling properties of the heatsink." Read this slowly: over-application of non-electrically-conducting thermal paste is not harmful. The heatsink clamp force is designed with the viscosity of the thermal paste in mind to generate the desired film thickness. It will just ooze out the sides. Someone who over-applies thermal paste, or uses thermal paste that is too viscous, might need to wait some period of time for the excess paste to migrate out. Until it does, thermals might be impacted a bit. It is well known in the OC'ing PC community that you need to wait a day or two for thermal readings to be meaningful.

    Apple admitted the service manual was theirs: https://gizmodo.com/thermal-greasy-apple-sics-lawyers-on-something-awful-171394 https://gizmodo.com/thermal-greasy-apple-sics-lawyers-on-som... "After a Something Awful denizen took apart his MacBook Pro and discovered that Apple had slathered on far too much thermal grease, he found that using a more modest amount dropped his MacBook Pro's temperatures by several degrees. Now the forum has recieved a threatening letter from Apple's legal staff, requesting a link to this image [pictured above] be removed because 'The Service Source manual for the MacBook Pro is Apple's intellectual property and is protected by U.S. copyright law.'" Like many others [1,2,3,4,5], I saw a lot of these MacBook Pro overheating issues resolved by removing the profusion of thermal paste and replacing it with a sane amount of Arctic Silver.

"But what really fixed everything, was replacing the factory thermal paste with my own application of Arctic mx-4. My core temps are now 15-20 degrees celsius cooler. No joke [TL;DR]Apple did a really bad job of applying the thermal paste on my 2011 Macbook Pro. So bad that the excess of paste around the diodes were causing overheating. I cleaned up their shitty job and put on Arctic Mx-4 and now my fps is higher than it ever was. Here are pictures of what I found. This is embarrassing because it makes Apple look pretty bad."

"I own a Late 2008 Macbook unibody, and lately the temps of the macbook were insane, until today. I was reading up on how Apple applies way to much thermal paste from the factory and boy were they right. I got around to opening the case and pulled the logic board earlier today. Looked at the thermal paste and it just seemed like they put it there. No real care for it working or not. Here: http://imgur.com/9z0cZwU http://imgur.com/9z0cZwU Anyways, I cleaned up the thermal paste, and reapplied Arctic Silver 5. It made a huge difference! Temp at Idle before were roughly 55-60 degrees celsius. Temp at Idle after are at 40 degrees celsius."

Too much paste reduces the rate at which the CPU transfers heat to the heatsink. Subsequently, temperatures (both idle and load) increase.
