D5 Noise.

You guys might have more experience with this pump then I do.

At first it was fine. Running it on the 5th dial and having Koolance CTR-SPD12X2 Dual 12V pump controller set at 7 volts for about two weeks now.

However as you can faintly see in the clip, the flowmeter is barely spinning, and as i ramp up the V on the controller, theres a huge whine sound. Is my pump fine and flow meter is just restricting? or vice versa.

In the loop.

7v is pretty low, can you not put it to 12v I know some D5 pumps can run up to 24v can't they?

I know but have you actually turned yours up to 12v to see if that is the case? It does look slow but then again if it is running at near half its designed voltage i would expect it to be that slow.  ;)

 

EDIT: also, if this pump is brand new, it could be trapped air in the pump, Dazmode did a customer build where he mentioned this stating customers often return the product believing it is faulty when all it was is air.

 

Second EDIT:

I just watched the video of Daz and your's back to back and it sounds the same, because you have used hardline tubing I cant suggest moving it around to try and dislodge the air, you could try tapping it ever to slightly to try and help push it out. It sounds like it's just plain air trapped.

ive been running the loop for 2 weeks, why would air pop up now?

Could of collected there over time? like tiny bubbles? I'm unsure as to how to get rid of the air but if you check out Dazmode customer build episode 3 i believe or tell me how to embed videos on here I could show you, it sounds exactly the same as what he is describing in the video.

could the pump be put on incorrectly or too tight by ek?

I'm sorry I can't help you with your question, but what is the little spinning wheel? I always wondered what those were for. Sometimes I just see them in random places on people's loops.

It's a visual flow meter @Spev it's to show you that the pump is still functioning and indicates your flow rate through your loop (depending on placement).

Possible but given you said that it wasn't making that noise then over the past 2 weeks the noise has developed I'm still placing my bets on it being air trapped in the pump top like Dazmode says in his video, he even shows you that the noise only starts at position 5 on the pump. Like I said, I'm not sure how to move the air other than gently tapping the assembly while you have the pump running at just below where the noise starts, you should see the bubbles go eventually but it isn't a 5 min job it takes time for the air to shift apparently. Are you certain the noise is from the pump and not the flow meter?

Turn the loop on, tilt your case and watch for bubbles, might be hard with the colored coolant, keep tilting it until the noise goes away, just trust me before you rip everything out and RMA the pump.

If I bought one, should I install it towards the end of my loop to ensure that water is being pumped decently enough throughout the entire thing?

yea im pretty sure its the pump, cause my gpu loop has its own pump and its dead silent.

The pressure in your loop will pretty much equalize through out so shouldn't really matter where you put it so long as it's not infront of the pump outlet, putting it near the res inlet would do fine or generally where ever you can see it best.

It's air, unless you ran the pump dry it will be air stuck in the pump top you have fitted, tilt your case until the air is pushed out and the noise should go away.

but that shouldnt explain low pressure even or if it does have that much air wouldnt it have that imprellor grinding sound?

How would u fix this problem then? i tried tilting it 90 degrees this morning, didnt fix the problem.

Like I said, it isn't a 5min job, it's trapped there for a reason, try a few positions for a good while and if the problem still continues then yes the pump is faulty, but in that forum post I linked you too, he said himself it was fine then all of a sudden it made noise much like yours.

So I contacted EK and they declared pump is defected.

Thanks for your inputs guys.

Sounds like an air bubble trapped to me otherwise the pump is bad. I have a non D5 variant and it doesn't sound like that running full speed.
