In any event, peak power consumption occurs only during 100% CPU utilization (and that power consumption depends somewhat on the mix of instructions, i.e., which portions of the CPU's processing logic is active). When the CPU is idle, it's power consumption (and thus its heat output) are much less.
I have a dual core.. and under regular use the CPU barely gets above room temp... well.... it sits at about 30 C. Regular use... email, web browsing... low demand stuff. If I load it up and do something that pegs one CPU to 100%, the temp rises to about 38 C. If I max both CPUs to 100% and leave it, the temp rises to 45 C to 48 C.
These temperatures would make a Pentium shiver.
So... if you're planning on doing things that will max out the dual or quad core, then things will get hot.
It's all relative. The Core 2 design is much more energy-efficient than its predecessors, including CPUs designed for portable use.
If you're using it more... for normal desktop type use, the computer will probably actually run cooler overall, and be a whole lot more usable when it gets busy doing something on one CPU.
If the system is assembled properly and the case ventilated properly, there's no problem, even if you're running SETI@home or Folding@home or any of the CPU-intensive distributed clients on every core.
