Here is too where I get a little uncomfortable with 1-2C figures.
1-2C at stock CPU speeds is a totally different matter to 1-2C at very highly overclocked levels.
A stock AMD XP-M 2500+ (1833MHz/1.45v) under load is putting out under a third of the heat of the same CPU when it's being run at 2800MHz/2.00v, or even 2900MHz/2.15v.
What I'm saying is that small differences at stock and quiet settings take on a much larger scale of significance when pushing the (computer) system hard. I believe that many people far too easily dismiss the scale of the heat load problem when pushing a system very hard. When you collectively (pump, CPU, GPU, etc) start pushing >150W into a radiator you do notice rather quickly that ultra-low-noise fans just don't cut it any more.
