Welcome to the forum
You can buy any CPU-cooler from aqua computer. With the right mount they all will fit on your board. The difference in performance between all blocks is rather small (around 1-3°C).
A performance chart would look like that:
1.) cuplex xt
2.) cuplex pro
3.) cuplex evo
5.) cuplex 1.3
As you can see, the cuplex pro has the best price-performance ratio.
By the way: your english is very weird. Looks like your are using a translator like google or bablefish ;D
