Your rads should be ok as long as you have enough flowrate.

Im not sure about the waterblock though, do you have a coldplate (1/4" prefered) and can you bolt it to the waterblock.

You will also need a high amperage PSU, I think you need 17amps at 15v for most 226watt TEC's but you better check before you buy anything.

Then you will need to insulate it up with neoprene which is an art in itself.

the real difficulty is the PSU as they tend to be hard to find and expensive.

Marvin, I messed about a bit with tec's and they ARE a headache! The best advice I could find recommends against the use of tec's on the newer AMD CPUs as the cost to benefit ratio just does not support it.

A good water block or a super-cooler like VapoChill or a Prommy is your best bet.

Thanks Daniel , I was just waiting this answer to cut it on my mind, but you know the addicition of computers.....
Here in Brazil we dont have very large cases like antecs, chieftecs, ....
so i had to cut the hdd rack to fit the hc, so it is ok.

Actually those 226w TECs actually draw about 360w, They pump 226w of heat from one side to the other and the rest is the loss of efficancy.

I have a 226w TEC and 500w 15v PSU sitting in my closet because I don't want to mess with the hassle.

I know the feeling Staz, I gave away a Vapochill rather than update it, way to much trouble when you can get great chips for cheap!

I also have TEC gear that I no longer use (promethia)

My 15v 40amp TEC PSU is now only running 6 120mm fans at 5v
