The new Koolance block, the 350, really isn't bad, they are starting to learn their lesson about using aluminum and this block has none.
However it is incredibly high restriction and performs slightly behind the big 3. D-tek Fuzion V2, EK Supreme, Swiftech GTZ.
So in terms of current blocks any of the aove will work just fine. Between the 4 were talking a difference of 1-2 degrees tops. Just know that the Koolance and EK are the best for cpu only loops, the gtz for loops with 2 blocks, and the D-tek for loops with more than 2 blocks.
