Fountain pumps work pretty well. I used one in an old rig way back in the day before all-in-one kits. I used a fountain pump (pretty darn good, as well as quiet), copper gas tubing, a solid copper block from Danger Dan (still in the drawer here), and a big copper radiator. Unfortunately, I was stupid and assumed I didn't need to cool the rest of the case, so it affected my caps on the motherboard among other things. The electrolytic caps (not those nice solid ones they use now) started leaking and bloating, but fortunately I had upgraded before that ever became an issue (a friend had one explode and kill everything).
It's amazing how much louder everything appears to sound when you have a very quiet system. I was obsessively trying to curb the sound my PSU was making because it was the loudest sound I could hear from the machine.
Yup, and I was just about to explain what you said. The fountain pumps are actually superior to the commercial water cooling pumps for CPUs. The idea is to get the most amount of water through the CPU block as possible. Even with that, you are still going to have an easier time and superior results with an air cooler like the Noctua NH-D14, unless you are additionally conditioning your water supply with a chiller to 10c or so.
BTW, the Noctua is very quiet, actually quieter than the Corsair H80 or the H100. I found the pumps made a rattling noise when i tested them. That noise comes from air in the lines.
Air in a self contained water cooler = bad design/poor heat transfer!
