i keep reading post after post about pumps. I completely can't decide which pump to get. Space is an issue for me. i keep almost ordering the quiet one 1200, because people say they work pretty good. then i hear they suck. then i think i will go with the mag3, then i hear it vibrates and its loud. i get the feeling that pumps are hit and miss. like if ur lucky u get a good one. if not it leaks and vibrates. if the quiet one 1200 isn't leaking and dieing after a week does it perform well? will it power a system with a chevette heater core, cpu, NB, gpu block?? what about the mag3?? what is the size and noise difference with these 2 pumps??
