New pump not running ?

Franco_cov · 23 Sep 2008 at 21:04

I have just put together my water cooling and i have connected the little adapter to my power supply so that i can power the pc up and not the board etc and have tested that there is power by connecting an led to the feed i am using fo my dcc 18w ultra pump and nothing not spinning or anything?

Any suggestions is there something i am missing? like i said its new delivered today so hopefully you aint going to tell me the pump has been delivered dead ??

Did you put a new top on it if so the screws could be to tight also check the pins in the molex as they can move a bit when you press them in to the psu cable.

whack it.. ddc pumps stick quite easily. Once its going they always keep going.

As young Anakin would say 'Hit the nose!'.

Or just give it a whack as matt said

i purchased it with the top pre-fitted the xspc resevoir. I have slightly loosend the 4 screws and tapped it and still nothing ?? Any more ideas

to be honest if you do have a sticky one its not a huge issue, not one I would consider draining a loop and returning a pump for BUT it is ever so slightly possible that if your pc crashes or you switch it off it could stick again.

this is a very common (I've had 3+ do it) problem with these pumps, to the point where there's no guarantee the replacement would be any better.

I just thought it was better to add a disclaimer because I found out the hard way years ago when my pc crashed during clocking, I rebooted it and it all started up fine but the pump didn't.. I noticed when I had a gfx card at 80c and the water was almost boiling.

A quick whack and it always ALWAYS worked but it was something to remember.

I guess if it was me, and it was brand spanking new then I might consider changing it. Mind you it would probably be easy to rig up the rpm indicator to a fan and have that shut down the pc if it booted at 0 rpm.

all switched on, filled with water?

its less of a tap and more of a tw@, maybe 2 or 3.. try that and if its still not working then its buggered.

More tips! (in useful mode tonight) get a pair of AA batteries (if you're using 1/2" or 7/16" tubing and you should be able to whip the pump off and block the tubes with the batteries rather than draining the loop.

i am using 3/8 tubes and the system has no coolant in it because the pump has not worked from the start ? Had the resevour full before trying to start it though

I really dont want to have to send it back time etc can i not take the top off and spin it by hand ?? to free it and then put top back on and try it? as I had the top pre-fitted to save me doing it :s

Franco_cov · 23 Sep 2008 at 22:27

ok i have taken the top off span it a few times with my finger and put it all back together again and still nothing? does this mean its dead ???

Franco_cov · 23 Sep 2008 at 22:50

Is the impeller (fan with magnet) loose? As in not pushed into the pump all the way?

I had the same problem with a Hydor pump, Luckily My mum(when I lived with my mum)
had a plumber in fitting new central heating so I cheekiily asked him to take a look at my watercooling and he fixed it in 2 seconds by just pushing the impeller in till it clicked into place.
