So I figure, "I posted Merom, why not post Yonah as well?". So there, another brag post from the official FanBoy of this site, yay (many called me that in an effort to "hurt me", sadly, they failed miserably, I'm even proud to be one!). This Yonah is really a nifty processor, very very cool. Compared to Merom in terms of temperature, I really can't tell which is cooler. In terms of acoustics/fan noise, both performs equally. Performance wise, well, I guess I'll put it thru the hoops and see the difference and/or similarity.
