Two Questions - A mini-valve Drain and testing the water system custom cooler - DOUBT

[Not411]

Hello everyone,

I have two questions and I really need to know how it works:

Question 1: The mini-valve to drain my fluid from my cooling system. Could someone tell me how it works or send me a video link?

Question 2: According to the first image, How do I mount the button on / off to test the loop to see if do not have leaks, I am confused where to plug the molex, to run my pump with the button on / off, as well it is easier to test the fluid in the system.

I have two loops:

Loop 1: reservoir bottom - rad - block Rams - cpu - mosfet - block Rams - reservoir top
Loop 2: reservoir bottom - rad - GPUs - reservoir top

Thanks!

Below the images.

The molex adapter on/off should just connect to your pump. However, if its a single molex you woukd need a molex splitter as you have two pumps to run simultaneously.

Regarding draining, your going to use mainly gravity/pressure to drain when you open the valves. However, by not being lowest point you may need to get creative to drain rad(s) in lower chamber. For my own method, I'm using two mini-valves. I close one to prevent coolant from going through loop, and open other to drain.

Nice setup, BTW

Thanks for your comment and your compliment, that my project has a lot of work.

I can do the leak test individually, I will test with distilled water, I want to first make the loop 1 and after the loop 2. I can do it this way?


The problem of drainage rad bottom, besides the creativity will need strength, because I'm using the Corsair 900D case and this very heavy.

Thanks!!

I know what you mean about a lot of work. Pays off in the end though Sure, you can test each loop individually. No problem there as its just checking for flow and be sure of no leaks.

How is that case? I had a loop a few years back in an 800D before my current and it was huge and heavy. Your 900D is even bigger, lol. For draining my loop, in combination with mini valves, and I hook up a length of tubing and quick disconnects. I then physically use my lung power and force remaining coolant out that doesn't drain using valves themselves. Not that difficult though.

Also, it would be nice to see some pics of your system when complete. Always like pics of new custom builds.

Sure, I will post more pictures of the project. Thank you for the informations.


So basically, is only open the mini-valve port to drain each loop?

Thanks again!

Sorry for late reply. To answer your question, typically yes that is how to use them. I actually have one in myself inline I close though first, then open another to drain.

No problem man, btw, what is these connections H_AMP_FAN and W_PUMP in my motherboard?

I can connect my fan 140mm in H_AMP_FAN? Already the door is very close to this fan. All other fans are connected in molex fans and splitters terminals.

I'm shitting in my pants to put distilled water in the system. Lol

They do what they say based on labeling. The w_pump is just a PWM header if your pump supported that, but your are D5 pumps I believe. Either way, the pumps still would need molex or SATA power. Using the header is just adding ability to control pump speed based on temp.

The h_ amp just means that header supports a higher amperage more powerful fan. Most motherboard headers are rated for 1A max. This may allow higher than 1A safely, though most fans are much lower.

Bad news, I put water in the system to make the leak test, this leaking in the two reservoirs, between the pump and the mod top, almost I damaged the system, I suspect the wrong installation of my pumps, modtop and reservoirs. I'll put at the pictures, now I'm really worried. I dismounted everything and dried up the water. What could be going wrong?

I'm suspicious that I installed the wrong kit (pump, modtop and reservoir)

The photos show the locations Leaked

Thanks for the help man.

some parts left over as I show in one of the photos, something wrong?

In this video below, I recorded my problem:

Having trouble with video link. Wherewas the wayer leaking out from, exactly? Around the o-ring reservoir bottom where it attaches? What are the parts you're using, such as make/model for pump tops, pump accesories, and reservoirs?

 

[Not411]

Sorry, my bad, try again https://www.youtube.com/watch?v=MgD4-hcuyqs.

This leaking exactly the two small o-rings of the doors OUT/IN the mod d5 adapter.

It has an o-ring thinner and other thicker. Has right side to put them?

 

[Not411]

UPDATE: My leakage problem is solved, were missing O-rings in modtop d5.

Here are two video youtube links of my system with water. The loop 1 this with lots of bubbles and air, how do you remove it? Some kind of fluid do I? I do not want to dismantle it to remove air bubbles system. Any idea ? thanks!

Another doubt, the reservoirs need to have the water up to the top?

You got some major air pockets in there. The one going to DRAM is particularly bad. May have to tilt and carefully shake system to work them out. I usually run my system a few hours to work these pockets out when draining and filling. Regarding other tiny microbubbles, they will disappear on their own over time. Takes a week or so in my case, but my PC isn't used daily.

How long testing? To be considered a safe system...

 

[1LiquidPC]

Well, thats always up for debate. Personally I do 6-12 hrs for a major overhaul/loop upgrade. There is no real set number of course. If it were me with a loop as complex and expensive as yours, I'd do 12 hours easy myself with frequent checks of coolant levels, fittings, and make sure no towels are damp.

Hi Bro 1LiquidPC, UPDATE:

 

[1LiquidPC]

Looking great
