The Pentium M cooling is included with the motherboard, AOpen and DFI. The heatsink doesn't even run and when it does, it runs at like 250 RPM. Still, if I overclock a Pentium M to 2.6 GHz and kick the FX-55's and P4EE's ass, then it is worth it. Plus, the one I'm getting costs almost 4/5 less than the P4EE and FX-55.
