Water loop not filling

[skillednewbie]

Sorry for another "loop not filling" thread, but I am very stumped and could use your helpful advice.

 

Here is an image of the loop

 

Swiftech MCP655 PWM is attached directly underneath reservoir. 

 

Loop order is Res/pump > GPU > 280mm rad (top) > CPU > 360mm rad (side) > Res/pump

 

Thank you!

Fill the res until its full. Turn on the pump. Turn it off right before the res is empty. You DO NOT want your pumps to dry out. Repeat until your loop is full.

Thank you for the suggestion.

I've topped off the reservoir. No change in water level.

If the water level doesn't change anymore just moments after turning the pump on, it should be full

Even if water hasn't filled tube from 360mm rad to res/pump and 280mm rad to CPU?

(Water levels still accurate that you might be able to see in image in original post)

Looks to me like pump has had it, unless you didn't power cycle for the pump to work?

Then you have trapped air, need to tilt the case with the pump turned off. The pump not being the highest component in the loop affects this many times more than the loop path/order

Just purchased pump Friday. First time turning on pump with res filled, the flow was very slow. Waited until about half full, turned it off. Filled it back up, turned it back on, and not much change after that. Maybe I need to get a replacement?

 

Attempted tilting case in many directions with pump off, water level did go down by about 1/4 inch. Not much has changed since then.

Need to fix the tubes for the gpu block. That isn’t going to work. Unless the picture is that bad and I can’t tell.

Could you elaborate? Are the tubing from the GPU to top radiator bad? From the res to the GPU? Is it a bad bend? Do I need to adjust the height of the pump/res lower to lower the pitch of the tubing to the GPU?

Thanks for your feedback. Sorry for the picture quality, I tried to get as much lighting as I could that could be helpful for you all.

 

I've put in an order for a different pump to possibly replace the one I have now to see if this will fix the issue. I will have an update by Monday.

Oh crap, there's a picture. Yeah...you need to use offset ports on the gpu block for it to actually flow through the fins. Still need to get that air out though.

Appreciate your specifying that. I'll bend another tube and see if that helps.

AFAIK that was just another issue of your loop, it has no bearing on your stated problem. The fluid is clear, right? If you fill the res, do you see the coolant enter any tube? Or is it just staying inside the res without going anywhere?

Is you're Pump Dead? I bought some 30$ 500L/H pump from China because it seemed like the ACR pump in the ek kit slowed down alittle bit.  And figured Id need a backup. The China Pump is a little Noisey but I do think it's performing slightly better and it holds like a 100ml more water...Gives the ACR a run for the money.

Good eye, good eye.

 

@JR88

Look at how the tubing for the GPU is hooked up.

There only ONE of the ports are used; there's no in AND an out.

Ok, since you noticed the fact that the GPU block is done is wrong, did you power the whole system up? Some PWM systems require a PWM signal otherwise they only work at like 30% power, which on a pump won't work at all. Without a PWM signal my D5 barely pumps any water at all. If you're using a jumper to power the PSU to keep the system unpowered for leak reasons, you'll either need to just power the 24 pin for the PWM to work, or get another PC and use the PWM signal from that.

A pwm pump with out any signal should run 100%

No, not all of them do. Evidently mine doesn't. It's easier to see on fans, most will spin at 100%, but some don't, depends on how the PCB controller on the fan implemented the PWM control.

Trapped air. It happens... I have even resorted to putting a tube in the top of the res and blowing to get the pump primed. Also if that is hard tubing which it looked like. . Then in am jelous of thoes bends
