This is the best 12volt pump I have gotten my hands on in the last couple of months since I start water cooling. My current system uses a rule live well pump that is loud and adds heat to the water. I got this one from ITT Jabsco today here are the specs.

(This thing is small enough to fit in the palm of my hand. Wish my camara was working so I can show you a pic of it in my hand.)
I pluged it into a power supply and it didn't make a sound while running in my hand. I set it on top of my case and it's still very quiet.
