I recently rewatched some cooling videos that LTT made (gold tub, delidding, liquid metal, graphite cooling pads) and, in one video, they found that IC Graphite Thermal Pads were as effective as most thermal paste. They are also reusable and eliminate hotspots (linus burnt himself while trying to burn a thermal pad).
Anyway, I was thinking about replacing the thermal solution in my mid 2013 macbook air because it doesn't cool well anymore. I was thinking about IC DIamond vs IC graphite, and the price of those pads (3cm*3cm $10 or 4cm*4cm $13) is scaring em away from them. I also noticed that there are a lot of generic thermal pads and wondered if any of them are any good. Have there been any head to head tests? Has anyone suggested this to LTT (I thought about it, but didn't want to suggest something he's already rejected)?
Also, I know Intel's thermal solution is designed for longevity over performance, as Linus described, but I wasn't sure about Apple's thermal paste. I don't expect to get better performance, but I would like to get better cooling. My system is always hot. It's not my main system, but, despite its age, I like to use it for writing and when I need something portable (my Lenovo flex 5 is a little bulky by comparison).
