Back in march I purchased my 13" Retina, unfortunately where I live there's tons of dust all over and even though I do clean the whole apartment every 1-2 days I noticed it gets noticeably hotter during some tasks (or few apps open at a time). Sometimes even only Photoshop with some music in the background and like one (srsly one) Chrome tab (I know they use quite a lot of memory, but it's not more than 1-2 and it didn't use to be the problem) make the fans go up to 4000 rpm or above. It's probably no use to disassemble the laptop just yet, I mean it's only a few months old, but maybe there are some tips to prevent further dust going in or sth? Frankly speaking, it irritates me quite a lot because I really try to take care of this thing and the results are not that good. I always used compressed air with my Windows laptops, but well, it didn't help that much + I know there are numerous disadvantages to it probably (dust going further in?). I'm not sure, I'd just appreciate all your tips to keep your mac clean .
