So I got my Lenovo IdeaPad Y570 a couple of days ago and I gotta say that I'm quite impressed . The machine feels solid, the touchpad is very responsive and programs like PCSX2 run pretty darn well on it. Despite these, I have some reservations that are more than likely to be trivial or downright nonsensical, and that is paying too much attention on the subtle changes. By changes, I mean, GPU giving off more heat when it's running a more intensive program than Chrome/Firefox, the CPU/GPU heatsink fan spinning up/down when needed, HDD spinning up/down when needed...all of these are things I pay way too much attention on. What can I do to assuage myself of these trivial nitpicking fears? Maybe it's partly due to seeing my brother's laptop starting to act up (heatsink fan is failing, causing random lockups), I don't know, or the fact that I don't want my $800 to go to waste. I know that laptops can take a great deal of heat before being forced shutting down (typically 80-90 degrees Celsius) by thermal sensors, I should enjoy using it (I am), but I want to enjoy using it even more and not worry for a second that it will suddenly stop working. What do you guys suggest I do? Should I get a laptop cooler or have a book placed underneath? This is the machine I got - http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPortal/en_US/builder.workflow:Enter?mtm-item=%3A000000F3%3A00004F62%3A The discrete GPU can be forced on at all times.
