I think the leak worry is overstated to be honest, but there always remains that possibility. It would be down to a botched installation in most cases though, as the components themselves rarely leak if tested and installed correctly.
Watercooling might not reduce your idle temps, but I'd be surprised if it didn't reduce your load temps.
Idle temps are nothing compared to your load temp. Your computer isn't crashing at idle is it, and nor is it likely to. Most heat related problems occur at loaded temps, for obvious reasons.
I might have missed it, but what case have you got, and what fans have you got ventilating it?
It could be your idle temps have something to do with case airflow, or lack of it. Does the idle temp go down significantly if you remove the side panel?
