As far as pumps go, these so called PC water cooling pumps suck balls as far as I am concerned.... bar none there simply is not a good one made IMHO
Eheim fish tank pumps will move some water, if you are handy you just need a relay to switch the voltage and make it come on with boot up. or a 120v switch will do, just don't forget to turn it on
They will whip the shit out of anything on these so called designer bend me over water cooling sites
I have a 655 .... total POS my 1250 smoked this thing. george has it now. back in the day they even had a PCI card to bring it on at boot ....
LOL we were making our own blocks back then....
Thats as honest as I can be
