Just got my 1600+ running 1600 stable too: 153x10,5 (didn't bother to unlock it). I use a PAL8045 with a Papst 46cfm fan, temps range from 38C to 40C. the vcore is 1,85 though, but I just maxed it to be sure it'd work, will see if I can lower it later.
IAMC4N4DIAN, you ask if it's worth it, well, you can get a really fast system cheap and of course there's the bragging!
And the difference, you can hardly notice the higher speed in normal use (Word, surfing the Net, etc.) but in games there can be a difference, I can tell the difference in Max Payne between 1,4 and 1,533 Ghz at least.
And as Rahminator said, if you are careful there's no risk of frying anything, it might shorten the lifespan of your cpu from 15 to 5 years, but who here in this forum will use the same cpu in 5 years?<FONT face=Verdana size=1>
