I haven't dusted my laptop in 2 years now (my apartment s very dusty)and the temps on the cpu are hitting 93 degrees so I think its time. I want to lower the temps more by changing the thermal paste too. I keep hearing people saying that the MX 4 thermal paste is great but it has 8.5W/mk while I found one from thermal grizzly that has 11.8W/mk. Will that make a big difference because they are quite similar in price(they're both dirt cheap)? Also is 4 gramms enough for my whole laptop or do I need 8 gramms?
