Aigo, whats the problem man. A waterloop on the CPU + NB is going to be a CPU loop only now with nehalem. It shouldn't matter to much for heatcontrol.

assuming your on water. LOL.

But the NB never gave off too much heat to begin with. :T

Im talking about the people on Air. :T

yesturday i replaced my fileserver's CPU from an Athlon X2 3800+ 2.0Ghz windsor F2 90nm 89W TDP, to an Athlon X2 BE-2300 2.3Ghz 45 W TDP...
The TDP went down from 89 to 45 watts on the "best efficiency" model. My idle system power went down 9 watts (110 instead of 119). My power during file transfer to the server stayed exactly the same (152 W on both), although it is a little faster, I think... I didn't actually check maxed out power since it will never be maxed out, it is a file server, it writes files and it sits idle... But during boot I saw the old chip spike to 209 and the new one will only spike to 179. but... a fraction second spike during boot up is not exactly indicative..

Interestingly, if the system is OFF and plugged to the ethernet cord, power consumption went down from 7 to 5 watts.

Still, I expected a greater decrease during idle... (it is still a worthwhile switch though).

Anyways...
AMD: http://en.wikipedia.org/wiki/L...8F2_.26_F3.2C_90_nm.29
Intel: http://en.wikipedia.org/wiki/L...Core_2_microprocessors

Notice how every family is the same TDP despite having a voltage range and different speeds.

Ummm...that's not an Intel Roadmap, that's an Expreview roadmap.

How efficient is your PSU in this wattage range? You might save more watts by switching to a lower-rated PSU with a higher efficiency in this load regime.

You can go for an FPS Zen which has a lot lower idle vampire draw, about half a watt with no load and 3-4 watts with a few miliamps of laod. Most of the power supplies i've used usually vampire some 10 watts. However they are pretty expensive and Fortron has been getting pretty low ratings recently.
