110W x 8, for the 8 celerons? Granted celeron uses less
than 110W, until that day they're ramped up that high (if
ever), but even so it all adds up. 110W is significant
because they are not yet (if ever) integrating
thermoelectric coolers. Getting rid of any given amount of
heat becomes more problematic because there is finite
expansion of heatsink size possible and nobody wants a loud
heatsink fan (save for a very silly teenagers).
If the heatsink continued to grow taller, it becomes a
significant mechanical stress, even if mounted to the case
wall behind the motherboard (through-board mounting), and in
shipment (remember that OEMs are always a large
consideration), such a large 'sink will flex the board as it
is mounted to the case wall even if only looser coupling to
the heatsink mount itself.
Increasing diameter of the heatsink pushes the power
smoothing components further away from the socket. Massive
numbers of large value ceramic or tantalum (or other solid
hybrid) capacitors become quite expensive, and nobody wants
to start mounting tall parts on the back side of a
motherboard for the obvious reasons. Intel has already
released preliminary information about on-carrier voltage
regulation but until we see that ship, how it will change
the landscape around the socket over the entire life (power
ramping) of any given family of CPU remains to be seen.
It's just much easier to air-cool a sub-80W CPU. You must
have some odd stores in your area if the typical light bulb
is 110W, around here it's considered 60 or 75W though as
much as possible I've been using compact fluorescents. I'd
put a full sized fluorescent above my workbench and
regretted it ever since, they flicker too much while the
compact ones are pretty good except for the slightly
greenish cast to the light (though that is getting better as
well but I can't bring myself to buy the premium priced
compacts when the generic ones do fine for a fraction of the
cost and eyes can acclimate to a given lighting hue fairly
well so long as it stays constant).
