Hi guys. Want to ask a simple question. I have asus r510jx (x550jx). My mobo was replaced after 2 months of buying new laptop becoz it was having some beeping problem when off. The person who came to change the mobo was sort of idiot because he installed old heatsink without removing thermal paste from that. I was not knowing about this type of stuff back then. Now it seems that my laptop cpu (i7 4720hq) temp r high (40-45°C on fully idle). Should I replace the thermal paste of my own. I can't say about gpu becoz I don't ever play on it. I am using it for music prod. Will changing thermal paste void my asus sucking warranty which is handled by cheap unprofessionals ??
