Hi, 

So, I've had my 17 R5 for about a year now and while I open the bottom panel and blast it with compressed air every few months. That isn't quite doing the trick anymore. So, I think it's time to get behind the fans and clean the dust clogging up the heatsink. I've watched some videos online about this, and this is where my concerns come in. Am I right in thinking that getting behind the fans involves removing the entire heatsink? If so, does that mean I'll need to clean and repaste the cpu and gpu? Considering how important it is to clean gaming laptops (more so than for desktops), in my opinion, this is a really poor design.
