Without doing it there is no way to know if your parts will do the job required. Oh, you could just read reviews , buy some stuff and hope it is good enough...but then you will most likely either not get enough cooling or spend too much money for cooling you don't need.

But it's a little more complicated than you suggest. The amount of heat the water carries away is dependant on:
The efficiency of the waterblock in transfering heat from the CPU to the water. This causes the water to heat up
The efficiency of the radiator in transfering heat from the water to the air. This cause the water to cool down.
And the temperature of the water along with the flow rate effects the efficiency of the block.
And the temperature of the air, the airflow, the water flow, and the water temp effect the efficiency of the Rad.

Have a look at some of these and you will start to understand. Then find the graphs for the parts you want to use and see how thay will serve you.
