First comment, on the bus situation. With the 533 bus, yes, it's equivalent to the "theoretical" max bandwidth of a single channel DDRII 533 module. Theoretical being the key word. Dual channel should allow it to max out that bus in real terms. Perfect solution? No dual channel and a 1066MHz bus would be, but you won't find that in a mobile platform (too expensive in terms of power) any time soon. In my testing this system is horribly bandwidth limited with single channel, bumping up the bus speed and going to 4:3 or 5:3 mem:fsb makes a huge difference. DC memory would be the next logical step.

The rad is a 2x120mm tranny oil cooler. I'm sure it could run passively, hell, I used the stock rinky dink heatsink passively at 1.7GHz. At the speeds and voltages I'm at now, and moving forwards to I don't know if I still could under heavy load.
