It all depends on what temps you are aiming for.
437w peltier would be the minimum for a heavily overclocked CPU. Note that you won't be constantly using 437w of power because peltiers run more efficient at less than their rated maximum power/voltage. I ran a 437w peltier on my X2 3800+ running at 2.5Ghz, and giving the peltier 13.5v produced -8°C or so load temps.
If you just need to lower your temps a bit you can just build a better wc loop. But if you still want a peltier, get the 437w module and feed it 5 or so volts. I did that and my load temps were ~30°C and everything was completely silent.
You'll need a coldplate and a large enough waterblock to cover the entire module. That's really the only tough part when trying to build a TEC. PM Burn and he can give you Devin's email, the designer of the almighty Arctic Web 437w TEC.
Edit: This post shows some pics of my watercooling loop and TEC setup.
temps i am aming for is about around 50c full load @ 3,6ghz
i refuse to give upp before i can have my ram atleast stock 800mhz
4ghz+ have to wait til i build my next pc so i can push this one farther
and still have pc to play with when it fries
btw a new watercolling setup is close to not going to happen before i build a new system (too expensive my system is 5000$+as is. im getting poor here)
a tec and a psu for that is way cheeper and i dont see on it as a waste of cash as it can get me far higer on oc than just a new water system
peltier 240watt, would i need a better waterblock if i doo that one, or should the one i have be sufisient?
nvm but tnx all for u'r help
i've been loocking into it a bit more and
doing a tec setup will be soo overkill
couse of the rest of the system going on water too i would need pelts all over or the rest of my system would be to hot, and doing that i would need a car engine radiator and that would just mess up the hole loock and loocks are important as i hafto stare at the freaking thing all day
maby one day i'l buy a wapochill and put in the case (have room for it, the lian-li cube case is a genius case)
dont think there something too wrong with my watercoling system as i had good temps with my 630 @4,2ghz, if i had my fan's blowing a bit faster then 550-600rpm i would be getting better cooling, tho im not gonna as it would be far to noisy for me.
i am gonna buy more radiator's thinking on two single ones to mount in where i have my other fans that give me some more cooling and keep in mind i'm alsow cooling my ram atm (gpu is going to be and northbridge too)
and i have a room temp at 21-22C
I'm getting really tired of seconding Pinhead but he's right; you definately do not want to run your 437W pelt @ 437W... I am running my 437W @ 13v and getting nice load temps around 0c on my FX-57. If you run it at 437W (24v) it might give slightly better results but it will also be pumping twice the heat into your WC loop which will cause your GPU and pelt to run hotter (assuming you are running both on the same WC loop). The problem with this is that you start pushing the maximum temperature differential between hot and cold sides on the pelt and I'm willing to bet good money that after a few hours of fragging your load temps will be as high if not higher than if you undervolted the pelt.
If you had unlimited cooling power to keep the peltier cooled down you'd probably see a descent difference but when you have limited cooling power, like a WC setup you need to find the most efficient setting for the peltier.
