Whatever happened to Peltiers?
seems like they might be nice with the new p4s because they actually have a heat transfer plate - haven't seen any discussion of these for a long time - are they just not powerful enough to deal with modern cpu heat?

Peltiers are still used by some hardcore overclockers. They're rarely used by the moderate overclockers who opt for Deltafans or watercooling. They're a hassle to setup.
You have to prepare your mobo to prevent condensation, you need an extra PSU just for the Peltier, normally a special 12V PSU. I guess it's just too much of a PITA to be useful for most overclockers. It adds alota moolah to an already expensive H2O setup, probably something like $100 minimum (that's on top of your H2O setup!)
Are you already watercooling ? If not, try that first before you think about using peltiers (peltiers require watercooling to get rid of the amazing amounts of heat they generate).
I'm watercooling one of my PCs and I'm happy with it, very good cooling at a moderate noiselevel.

Nope, Dangerden offers a 226W/15.2V peltier which can handle any CPU out there.are they just not powerful enough to deal with modern cpu heat?

I am an ex-peltier user. When I went from a PIII to a T-Bird, the whole peltier thing got much more expensive and more complicated. Problem one is the heat output of current cpu's. While you could get decent results with a PIII with a 70-100 watt pelt, T-Birds and later cpu's put out enough heat to overwhelm pelts with these ratings. To use a pelt now, you have to find one that is like 150 watts. These are little bit hard to find, particularly at 12 volts. The second problem is finding all the power you need to run a 150+ watt pelt. You are not going to find a cheap power supply that puts out 13-15 amps at 12 volts.
So if you want to use a whopping pelt now, figure you spend $45-50 after shipping for a big pelt and at least $50-$100 bucks for a power supply just for the pelt. At some point, even though it is heresy in our community, it is just easier to put that $150 toward a a faster CPU.
Of course, I am thinking about putting my old pelt (which nobody will buy now) on my video card
