Please advise./QUOTE]You'll need fans too...and they make noise just like your CPU cooler and GPU fans do.
The ticket to "quiet" WC'ing is large radiator(s) and quiet fans.
That pump will be OK with any CPU/GPU blocks. With blocks higher water flow rates have diminishing returns. After 2 gpm, more flow doesn't have much effect.
With radiators though it's different. The effect of more air flow much more linear.
You can look at it this way:
A 120 x 1 Rad with a 200 CFM fan would be equal to a 120 x 4 Rad with 4 x 50 cfm fans (well, sort of).
A 120 x 1 Rad with a 50 cfm fan would be ...well, quiet, but useless for cooling.
A 120 x 4 Rad with 4 x 200 cfm fans would be awesome(ly loud).
