I originally bought my Eheim 1250 from Danger Den over 5 years ago to build my original watercooled system and this Eheim 1250 is still going strong without any failures. And this is with constant usage running 24/7/365. I read of people using all these 12 volts pumps and that might be handy, but it's hard to argue with the reliability of Eheim and their pumps. They have a reputation for reliability in the aquarium hobby that fully carries over to the watercooling world of computers. Zero leaks, zero problems, zero repairs in 5+ years of continuous service cooling processors.
