If you buy Acer laptop, it will sure overheat. They fans will go spinning like crazy with noise. And if you check it, acer laptop have only temp sensor for hard disk. Don't have sensor for CPU temp. Acer HDD temp already high (55 C) compare with other brands (42 C) so what do you expect from its CPU temp? Sure damn high until wanna overheat n burst. So stay away from Acer for a peace of mind.

I use the Cooler Master Notepal aluminium cooler and it really works to bring down 5 C on my lappie.
