Hi all, i bought the Razer Blade 15 (2018) few days ago. i open the back and want to upgrade my RAM, look what i found is "why my heat sink is different with the others one & website?" This is my heat sink. This is the international one. 1- it is not Graphite-based 2- can't find any Nanoparticle thermal blockers 3- Missing of the "6" point which is "the black, reduce the heat transfer" After we inquire the HK authorized dealer, the item"6" was deleted from razer website. i dont know whats going on about razer. We just found lot of the buyer a full copper surface heat sink and same as my problem, would please razer give us an official reply for this problem. We are buying a high quality product, razer you are proud of heat reduce technology on this product.
