I am thinking of buying a Sony Vaio SA VPCSA490X (link below) as it is on sale nowadays. However, there seems to be an issue with the fan being very noisy and the laptop overheating if put under stress. I was wondering if there was any truth to this and how distracting is the noise. If the noise problem exists, is there any fix (official/unofficial)? I ask this because I read about a bios update from Sony that fixes the noise problem, but also lowers the laptop's performance. That doesn't really seem like a real fix.
I was also wondering if these issues persist in the new line of Ivy Bridge S Series?
