Strange. But also who is the target audience for the review? Hardcore gamers, casual gamers or people that use it for studying, ie. webbrowsing and use of office suites? I don't mind that it soars up to high temperatures momentarily, but when gaming it might be 1-2 hours of 90 degrees straight - and I don't think that is advisable in the long run. Also for instance I had the Macbook (1st gen) which got outstanding reviews, but it got super hot too - I think if reviewers of the Macbook did the review with gamers in mind, it would have received lesser scores because the fan goes on full hairdryer effect when the graphics are pushed just a little bit.
Also I have a feeling I experience fewer crashes-to-desktop with the reduced CPU output/reduced heat, but that might just be a "feeling".
But something seems to indicate that high temps is inherent to the Sandy Bridge's. A user here on the forum showed me a review of my laptop (configured with an i7 instead) and there was mention of high temps there as well.
So to be on the safe side, I am going to keep going with underclocking it. Somethimes I can game for 4-5 hours straight if I got nothing else to do, and I don't think sustained temperatures of 80-90 degrees for 4-5 hours in a row will do it any good.
I am very very thankful for all the help I have gotten. I still have 2 questions though:
1) Generally speaking is an underclocked i5+Geforce 540M 2 gig "better" than the same processor with unmodified clock speed+Geforce 520M 1 gig?
2) What temperatures should I aim at when gaming, as a "rule-of-thumb"?
