Please help-pulling hair out

Well its official I give up.

I changed the loop around checked the both pumps. re seated the jet plate inside the water block. I even took out the cross chiller. out of the loop. I even made sure the out of the pump/res went directly into the inlet of the d5 in port. and still the flow is crappy.

So its either the pumps are nto up to it, or the rads are really restrictive. either way I have tried.

Bare with it for now and I'll work out your pressure drop if you give me a list of your full loop?

Waiting for my D5's too then I can sell my DDC's and serial pump top and I'll see how mine goes.
 
HardwareLabs Black Ice Nemesis 480GTX®480
HardwareLabs Black Ice GTX Gen two xtream 360
OcUK Tech Lab - XSPC D5 Vario Pump & EK-D5 X-RES 140 CSQ Value Combo(changed the tubs res to a 240)
EK Water Blocks EK-D5 Vario X-TOP - Acetal (incl. pump)
I have now taken the mobo block out of the loop(the built in one)

Thanks for the reply
 
At the flow rate you are getting, those rads test out at 0.5psi pressure drop, even at 1gm they rise only to 1psi... Big for a rad yes, but twin d5's should be able to supply something like 10psi, even allowing for the cpu block, tubing, fittings etc you should be running at about 6-7psi output (3-4psi of restriction), which again on the dual d5 pq curve should put them at well above 1gpm... I cant be bothered to keep flicking between charts to work out exactly where it all crosses over, but it should be well north of 1gpm, not down around 0.5

Looking at the exit of the top rad, to bleed that properly you are going to need to basically completely invert the rad/case

So are you saying I should be getting more than I am, because I have no idea how I can actually get more ?.
Also bare in mind most the charts show dual pumps, but connected via dual pump top. I am not using one of them. sunno if tha tmake sa diff.

I have tried bleeding the rads on each side of the case. dunnow hat else I could do.
 
Yes you should definitely be getting more. It points to a problem like air being trapped, or something in the wrong way round, or kinked up tubing, or a faulty pump or something

there is definitely nothing wrong with your choice of components, there is something wrong specific to your current installation

In terms of bleeding the rad you need to think about how air will want to float up and you need to give it a new "up" as well as an exit path, air is probably collecting in the end cans of your top rad, so ideally you need to turn your case completely upside down (pumps off if needs be) and rock it front to back
