loop won't prime?

[MayflowerElectronics]

I'm having one hell of a time getting this computer to work.

 

I'm currently trying to prime the system and I'm not getting any movement. The reservoir is full and it's not pushing any water through the loop. I'm 99% sure I have the loop setup correctly.

 

I've attached a video showing what's going on and showing the loop.

So the output is the most top fitting on the res. From the output it goes to the top triple 120 rad. From the rad it goes to the CPU, CPU to the parallel video cards, then the cards to the bottom dual 140mm then from the rad to the inlet of the res.

 

Any clues?

I dont see any mention of a pump? or is it a res/pump combo? I will wait for the vid to see what's wrong.

What res and what pump?

Where is the input to the pump? (I'm guessing this is a pump/res combo but I really have no idea from the way it's described)

[MayflowerElectronics]

Yeah, sorry. It's a pump/res combo. It's a PDWM swiftech pump. Video is 80% done.

Here is the video -

Have you plugged the PWM from the pump into the board (even though it doesn't have power)?

I can't tell where the inlet to the pump/bay combo is - does it go swiftech res>bay res+pump>outlet?

[MayflowerElectronics]

The PWM plug is hooked into the motherboard, the power it seems is coming from the 4 pin molex that its plugged into right now.

 

The inlet is at the bottom of the bay res. Where it loops from the bottom 240 rad.

:huh:

Is the pump making any noise at all? I would double check the Molex connection and plug something else into it that you know functions just to test. If the PWM from the pump is plugged into the board try unplugging it and giving it a power cycle, although I vaguely remember mine having to be connected to run.

Well the thing is the motherboard isn't on so it's not sending a PWM signal to the pump. Is this why?

 

I can't really hear the pump over the fans, but I can feel vibrations in the lines and on the pump so I think it's working fine.

The pump runs at at around setting 3 without a PWM signal.

 

You may have a blockage due to an air bubble, try to run it with the reservoir open.

I did, multiple times. I've also flipped the computer over every which way to try and get the water flowing. Is there still an air bubble somewhere?

Well yeah, there is a massive air bubble in your loop where the air still is. Did you fill the loop up to this point by just tilting or did the pump ever start? Also, turn off all your case fans to hear if the pump is on, you don't need them unless you are going to be doing a very very long leak test.

Alright, I'll try tomorrow when I get some free time. I filled the res, turned the pump on and it very slowly started pushing water through the loop. After that I just started tilting the water in the loop.

 

Although shouldn't it drain the res very quickly when you turn the pump on?

 

And I'm pretty sure my loop is set up correctly, is everything okay?

What is the exact model number on the res? Is the pump mounted to the res with a retention block, and is the outlet attached the retention block (that the pump is mounted to) or the res itself?

I took the stock pump it came with out because it was loud and swapped it with the swiftech pwm version.

If you're sure the pump is on and trying move water, the only thing I can think of at this point is to pull the res and pump out, unmount the pump, and make sure there isn't a blockage (rogue O-ring).

The pump moves water very fast, it should empty the res in seconds, so no everything is clearly not okay.

 

Did you touch the jet plate in the CPU block. I think that may be the cause of the problem. Another potential problem could be that the fitting on your CPU block has bottomed out, leaving no-where for the water to flow. I am concentrating on the CPU block because that is clearly where the issue is. You can see the tubing is full up to that point. Worst case would be you having to take to loop apart.

Is that the alphacool bay reservoir that has the round metal fill port that does not allow you to fill the reservoir to 100%, if so that is just a characteristic of that reservoir. Air almost always gets trapped in the reservoir and just won't move and the SLI block is not helping either. You will need to tilt the case to allow the air bubble/s to naturally move. Just make sure all ports are securely closed. You can also try to run just the CPU and then add the GPUs one by one to try and flush the air out.

Looks like the Supreme LTX (centered EK logo), so no jet plate. Although it could definitely be bottoming out.

I know everything isn't okay lol, I meant how the loop is set up. 

 

What's the jet plate in the CPU block? Should I drain the loop and try again?

[Trik'Stari]

If that's a larkooler kit, get rid of it. The pump is shit and the res is impossible to clear of air (at least in my experience)

The jet plate is a plate with slits in the CPU block to direct the waterflow. EK usually supplies you with 3-4 of these. One is blank to allow you to cut out your own holes but the blank one doesn't work if the slits aren't cut out. It seems you will have to take the loop apart. You could then at least test if the pump works out of the loop by just connecting the outlet directly to the inlet. If it does the next suspect would be the jet plate and lastly any fittings that bottom out, this is what that would look like.

 

 

If that does not work then I suggest IM'ing me/B NEGATIVE/Airdeano (sorry if I missed anyone out) as you are having some serious problems with something.

 

EDIT: Before draining your loop check that you have no kinks in your tubing, specifically around the back.

I'm draining it now and it's a bitch. I don't see any kinks but you're right I'm pretty sure it's the CPU block. Everything up into the inlet is fine, but the outlet of the CPU block struggles to push anything out. I'm going to try and loosen the fittings.

 

The CPU block worked just fine before I swapped in the 980's, I'm not sure what happened.

[MayflowerElectronics]

Update - So I'm pretty sure I went over everything I could, re seated the pump, ect ect ect.

 

There are no kinks in any of the tubing that I can see.

I am of no real assistance but perhaps @JayzTwoCents would be kind enough to lay some knowledge down for us.
