I'm going to web-note the seller about this but I'd want to see your opinions first.. So a year ago my parents bought two MSI GT640 laptops, one for each. Lately my dad's been complaining that the fan was running loud and asked me to check the temps. Having 2 perfectly identical machines in the same house and ambient temperature it was easy to do a reliable comparison. Using realtemp on both systems just showing the desktop with no background processes except the basic ones - I got 45 degrees for mum's machine, and 60 degrees for dad's. The latter put me off from testing load temps.. Probably dad's accumulated more dirt and fluff inside since he uses it for ~ 7 hours per day as opposed to mum's 1 hour a day... But the problem lies here. I turned the laptop upside down, it seems easy to remove the bottom for air-blowing. But there's a sticker covering the crucial parts which need to be removed, saying "warranty void if tampered with". So taking it apart is out of the question. Is there a way to clean it effectively then? There's still 2 more years remaining of warranty, so that sticker is kinda precious for now... I know I can blow out the vent at the side with compressed air, but wouldn't that just dislodge the dirt and re-lodge it elsewhere inside? I hate to think of the fate of this laptop if I leave it like this for 2 more years. I do clean my own laptop regularly by opening it, and even replaced TIM for gpu and cpu.. but mine never had that sticker. What are your views?
