Thermal Paste and Thermal Pad on CPU
The i5-5257u Processor in my MacBook Pro 13" Retina (early 2015) has 2 chip dies on the CHU chip carrier.
The thermal paste is only applied on larger CPU die. The Platform Controller Hub chip die (PCH) on the other hand is not covered by radiator and it also does not have any thermal paste!
You could cover the PCH using a thermal pad and it will contact with copper tube. What do you think? I think it will be better way to cool my MacBook Pro.
P.S. Sorry for my bad english.
Is this a good question?
