How to use Leakshield and other AC electronics best?

Samstag, 1. April 2023, 19:47

Hello!

I'm in the finishing stages of building a brand new system and I've selected to use a few AuqaComputer parts for it. I connect everything to a Hubby7 USB2 hub (set to sata, not USB, power). As controller I use the Octo and I have the power switch connected to it's Signal connector, all my fans and rgb is also connected to it (So nothing controlled by motherboard). I have a AquaComputer reservoir with their D5 Next pump, the Leakshield and for the loop a High Flow Next.
As of now I have the remove the sata power from the pump to play with the Leakshield as none of the AC devices will turn on unless I turn the computer on, which with an empty loop would kill the pump (would switching the Hubby7 from sata to USB power allow the devices to be on while in standby?).
The manuals aren't all that good so now I hope some of you experienced users could help me a bit to use these parts, especially the Leakshield. My first task I want to figure out is how to pressure test the loop (how to operate that and read the result). I think I got it into test mode, but can't figure out what it is doing or the result (All I see is some rolling numbers, it switches to another tab showing no values, then back to the page with rolling numbers). After that I need to learn how to fill and drain the loop with the Leakshield so I can clean and flush it before use.

Any helpful links to pages or YouTube videos would be very welcome.

These two screens keep alternating on the Leakshield when i put it in test mode.

I believe you would be able to operate the leakshield if you connected it to a USB header, as you should then have 5 volts from the mobo even with the system off (typically).
The spec on the leakshield for current draw is 500 mA, which is the max for a standard USB 2.0 port, so it would need a single 5 pin connection for itself.
The highflow next also has functions it can perform while the system is off, I am not sure about the d5 next.
Were it my system, I would connect the hubby7 to one side of a USb 2.0 port on the mobo, and the leakshield to the other.
I would then set the hubby7 to take 5V from the USB port, with the other aqaucomputer devices on it.

Doesn't seem to work for me. I've got the D5, Leakshield, Nextflow and Octo all connected to the Hubby7 which is connected to the motherboard. The Hubby7 is feed from the PSU and set to SATA power. All the AC devices are dead until I turn on the motherboard, get no power on standby. (so I had to disconnect the pump as I can't have it running dry).
I will try your suggestion, thank you.

I'm trying to figure out how to leaktest my system and read the display on the Leakshield.

The peripheral ports on your PSU shut down when the system shuts down.
Having the hubby7 take 5V from the sata port means you have no 5V when the system is off.
The USB 2.0 ports (typically) continue to supply 5V even with the system off.
If you set the hubby7 to take 5V from the USB 2.0 port, it has power even with the system off.
But the leakshield draws up to 500 mA, so it has to be connected to a USB 2.0 port all by itself.

Ah, thank you for that explanation, so your suggestion should fix my issues and allow me to play around with my devices without risking ruining the pump.

Ok, I followed InfoSeeker's advice and now the LeakShield gets power from the motherboard on standby (Hubby set to get power from motherboard too). The D5 Next electronics connected to the Hubby7 still doesn't get any power until I turn the system on (But the HighGFlow Next does for some reason).
My inability grasp the leaktest function of the LeakShield seems to be down to my loop not being tight, when I plug off the reservoir alone it seems to be sitting nice with a 0mbar leak rate. (What would be an acceptable leak rate?)
Guess I now have to pull the fittings etc apart and connect one at the time until I have a sealed loop.

The reason the pump doesn't function when the system is off, is it needs 12 volts for the pump, which only domes on when the PSU peripheral outputs work with system running.
