Anyhow if anyone could let me know if I am totally whacked or not it would be appreciated thanks

The res has an absolutely negligible effect on cooling, unless it is massive. The water spends only seconds in the res. Even a massive res will increase the time to reach max temp, but not actually lower the max temp alot.

The res simply acts as an air trap, and can simplify filling.
