Diyinhk pcb for ddc pump

red eye · 16 May 2017 at 11:56

any one has one fitted to a ddc pump?

I'm having issues with stock pump. It does not pump until a few seconds after post. I have increased post delay in bios to max but I still get cpu fan error when booting and I have to wait watching bios screen to see the pump has started.
I was wondering if the pcb would sort it or if there's anything else I can do or try?

i replaced my old 10watt ddc which was doing the same but a year and a half of it been working perfectly. I thought it was dying so I replaced it with an 18watt, that worked fine for a few months so I rma'd and the new ones doing the same.

I also have a pump res combo from an ek kit that works without issue I have thought about add that to the loop to the mobo header and power the ddc from my aquaro 5. Basically I want the ability of bios giving fan error/shutting pc down if the pump fails.

Any thoughts, opinions or advice?

Far as I am aware no pump should need a "boot up time"

If its still new I would be sending that back and getting something else sir.

I realise that's a lot of hassle...

What was left of the warranty after the last rma has run out so I'm stuck with this and I have pimped the pump with the aluminium housing and the rubber feet.

The impeller just sort of moves forwards and backwards a few mm for a second then stops for a few seconds then repeats, it does this for a bit then the impeller spins as it should.

That sounds more like ti beileives the impeller is stuck or having too much force needed to actually start to spin.

I don't know much any DDC pumps im afraid but that really isnt right.

Your not using pastel coolant are you?

What's the issue here? How long does it take for your PC to POST?

I take your PWM is plugged into a motherboard header?

Pump is plugged into cpu fan header. Every time I turn it on post stops with cpu fan error and I have to wait for the pump before I can restart.
But once its going there's no issue.

VKleita, I though it might be seized but there's a black mark on the impeller I can see though the pump top it moves around so I know it is spinning I have also had it apart when I replaced the pump and when I rma'd the new pump the ceramic ball is still smooth and the cup in the impeller has no damage.

Not my vid. But My pump does this but does eventually start.

Just to add that there is clearance between top of impeller and pump top.
I screwed the top to the pump until I saw an even and continuous oring seal (I polished the frosting of the pump top just for this)
