How hot are you running your water ?
My water is around 29 (idle) to 31(full load).
there should run around 5,5l/minut thru the system.
My system is build up so the water is running thru my pump and split in to two pipes. both thru my hdd cooler (5 discs), going to the MB blocs mosfets and nb and sb. going in to one pipe end thru my cpu cooler, thru a tubemeter at in to my radiator. my fans is running 600rpm and im having a 360mm radiator.

I have just bought a Gigabyte Odin GT 800W psu and a asus 8800gt 512mb top grafic card. im vant them both water cooled. that is about 250W more i have to deal with. im thinking om taking the water after the cpu then thru the psu and then the 8800gt.

So Im thinking on just let the water temp rise so i dont get more noise. but is it a good idea ? my hdd's is so essential. I have enen a little idea where they get there own pump an radiator. but im almost out af space.

My final question is still how hot do you run your water and your adient temprature.
