I have an old MacBook Air 13' 2011.
I'm not particularly facing any critical heating issues, although during high load temperature can go as high as 90-100 °C and aluminium case becomes so hot, it becomes somewhat uncomfortable to type.
Under regular load (safari, couple of regular apps) temperature stays around 40-50 °C.
Do you think changing thermal paste will help to decrease peak temperature by few degrees? I've heard Apple uses (or used) paste of such good quality, it's barely needed to change it.
Any recommended brands?
During laptop lifetime, I changed SSD, screen, keyboard, battery, cooler, but never touched thermal paste.
