Koolance pc1 problems

[Willseyvilleny]

I have had this koolance pc1-650 bk for a long time and it hasnt really worked, it will turn on then intermittnetly turn off, so i stopped using it, i finally got around to putting it back together for some good ol opteron overclocking, and low and behold i found out why it has stopped working. The capacitors on the control board are leaking. I was wondering if anyone else has had this problem, and if anyone has an easy work around, like hardwiring the pump on or anything, Any imput is appreciated, as i would love to have this working soon.

I've tried wiring the pumps in an Exos straight to 12v power but oddly enough they'll pump one tick and quit which leads me to believe that the controller board in the Exos turns the 12v d.c. into 12.v a.c. and here's why, if you hook the pump up to 12vdc in one direction the pump swings part of a revolution then if you reverse the polarity it will swing the rest of the revolution.

I've never taken a multi-meter to the control board to verify it but the only time I've seen this sort of thing happen is with a.c. motors on d.c..

i have an ac adapter, i wonder if i wire it up what will happen.....

I've heard it was a common problem among the early Koolance systems. Failure of the control board was often to blame for pump malfunction. Honestly, best thing you can do is take out all the Koolance garbage and just use the case to install a custom watercooling system that's actually capable of cooling something.

im going to try an ac motor, i dont have much ot lose.

i think it uses like 15.5v ac, cant think of how many amps

maybe not though, but thats what my multimeter said without a load on them
