You think that will make a considerable difference? I may consider it myself.
Careful. A lot of people are throwing that idea around. It's fine for those with experience of course, who can afford and are well aware of the possibility of losing their money should something go wrong. But it's a very bad idea for anyone that can't afford the risk of throwing money away, or is at all unsure of what they are doing inside the machine. Always,
always after a new refresh, people start saying their MBP's run hot. It is rampant with the 2011 now, it was rampant with the 2010, it was rampant with the 2009, and on down the line. It always fades, and come the next refresh, it crops up again. No idea why. Guess what? All those machines that were "far too hot and Apple did wrong", are probably still kicking just fine these days.
Best thing to do, is just get your machine, and enjoy it. If it is one of
very few that actually have a problem, it will be covered and replaced by Apple. And be aware that if you're doing things these machines are not designed specifically to do, ie. running Windows, gaming heavily in Windows, or even OS X, it will get much warmer than doing "normal" tasks that it was intended to do. It's by no means bad or unsafe to do those things, but be aware it taxes the machine harder, and it will make it much warmer.
If you open it up and take matters into your own hands, and something goes wrong with your work, or with the machine down the road, even possibly for an unrelated matter, your warranty will be void. Your money will be gone. That's worst case, granted, and very unlikely to happen

But weigh that choice carefully. Once it's done, that's it. It sure would suck to fine tune (and that's what that mod does, it finely tunes something that was already well within normal and safe ranges, it is by no means a fix for any kind of problem) your new baby, and then lose a ton of money later because it voided the warranty
