I just noticed...

that some pics of water cooled PCs have the exhausting water run to the intake of the N. Bridge. Is this common??? And is it even important to put a water block on the N. Bridge??? I was think I would skip it and do my vid card though???

[CrashOveride]

Unless you run REALLY high voltage and/or must have the last few mhz out of your memory board you don't need a waterblock, just better than stock coolling for most OCing needs.
Yes, it is common among people with watercooling systems though. Putting a waterblock on your Video card is fine too, but again, not really needed unless you like getting the max OCD:D

A waterblock on the northbridge can get those few extra megahertz out of a board. Remember, the processor is not the only part of the system that can reach its limits.

you should skip running a line to the NB, unless you are really at the edge of your systems envelope. if you run a line to your video card, make sure you run it parallel to your main WB, not in series. the drop in efficiency is appreciable when you run them in series.

i was thing the same. i was also think of runing a water block on the NB in parallel with the cpu but maybe ill just skip it. im happy with my FSB now. thanks guys :)
