For the CPU:
CPUCool, CPUFSB, ClockGen, SetFSB will all work.
For the GPU:
PowerStrip or the "coolbits" tweak (do the registry editing yourself, don't use a program that does it) will work.
3.2 is a no brainer, putting a fan on the norrthbridge will help as it will get pretty hot.
3.6 will need better cooling, especially the northbridge.
4.0 is beyond air cooling.
Good luck!
