If you're worried about the heat that your pump puts out heating the water too much, you could also run your system so the line out of the pump goes into the rad, then into the block on your CPU (assuming you're not running it like this already).
That would make sure the water is at its coolest before it hits the CPU, but it would also mean that you're storing hot water in your res.
Just something to think about.
