Please Help! VPP655 issues

post #1 of 5
Thread Starter 
Hey OCNer's
I've had a watercooled setup for a year or so now in it's current form and last time I went to change out the water (distilled and kill coil combo) and inspect the CPU/GPU blocks for gunk etc,
I managed to spill some water on the pump and it refused to work after that, having given out that magical smoke..

I bought another VPP655s and took the old pump out of the Alphacool top, swapped them over and the new one didn't work?!?

Ofcourse I filled the system up and done my best to remove air bubbles, which isn't so easy without the pump working...so it wouldn't be an airlock i'd assume

So I RMA'd the pump and the replacement pump doesn't work either...am I missing something really obvious?

Setup is (res mounted on top of the high flow top) pump>240 rad>120 rad>240 rad>CPU>GPU>res

What's the likelihood of getting two dead pumps? Please help I am at my wits end!

Have you tried using a different molex connector on the PSU?

I did and got nothing at all, i came to the conclusion that maybe the 12v on the molex isn't giving out enough current to kickstart the pump,
so I then tried a different psu, then kind of following on the same theme I wondered if the 12v cpu power would work the pump...
it did but surely the pump is drawing too much current? why would it do that?

Is it possible that the high flow top is too clamped against the im/propeller too tight so the pump is facing too much resistance?
I don't have another top to test it against but I feel this may be the reason as it takes a couple of seconds from cold start for the pump to spool up to top speed on setting 5...

Does that make sense?

That's a possibility. I remember now that I had something similar with a fitting that must have had a thread a little bit longer than normal on one of my 35Xs that stopped it working.
