It's admittedly been a while since we heard about some Lenovo S10 users' issues with heat dissipation and increasingly aggressive fan noise. Two years on, and one frustrated owner has taken it upon themselves to get inside the netbook and solve the issue. The result? The removal of a metallic-looking dust filter from within the left side vent, which is apparently enough to pacify the fan on this particular machine. We'd temper this solution with a warning: that cover was there for a reason, presumably a dust-related one. But, if a quieter machine is worth the price of a new netbook in the (not-so) long-run, it may be worth a try.
