I have the 2017 15'' MBP, with Radeon 560 Pro inside. I've read that some people recommend changing the thermal paste, because it is not being applied correctly in the factory. Now, I don't have any problem with my MBP, but I also didn't stressed it much. I know this would void my warranty. But, should I change it? I just want my MBP to be perfect, that's all.
