Shutdown using output actions

Sonntag, 12. Januar 2025, 11:21


I just installed a new high flow next while upgrading to a 9800x3d. I had a high flow lite but I suspected it of being a noise nuisance. I have been using target temperature (of water) with a quadro to control fan speed. I have a virtual software sensor of Delta T the difference between water temperature and ambient case temperature (which can be negative when idle and goes to approximately 3 degrees under load as shown on screen with help of msi afterburner and HwInfo).

Then I have a low flow output (output actions) to send a shutdown signal to the PC if the flow sensor drops below a certain flow value. This is incase the pump fails (I have ek dual pump) or leak (heaven forbid). The signal works without a cable and is a soft off ( like if you tap the power button when PC is running).


I was wondering how you fit a direct cable connected to the power button header of the motherboard if its already in use! ?(

Are there any other functions I am missing?
How do you configure the high flow next built in LEDs? By default they loop around the high flow next.

The Octo and high Flow Next have a Signal header that can be configured to output a temporary LOW (like a dry contact) across the pins. Cable #53216 plugs into the Signal header. The other end has a split cable - one side plugs into the Mobo power switch header. The wires from the case power switch plug into the other side. This puts the cable from the Signal header in parallel with the contacts from the power switch. I attached a picture with labels that show how this cable gets installed. When the Alarm is activated, the Octo or High Flow Next outputs a 1-second LOW on the pins which emulates pushing the power switch. I don't think the Quadro has a Signal header so it does not support this feature. To use it in this way, go to the High Flow Next Alarm tab and click the button for "Power Switch, switch 1 seconds at alarm". Connect Cable #53216 as shown in the picture. BE CAREFUL when you set up the Alarm. When I first did it, I made the mistake of testing it with a condition that occurred during startup. The result was every time I booted the computer, the Octo would immediately shut it down. I had to disconnect the cable so I could boot, then get into Aquasuite to change the Alarm trigger.



High Flow Next LEDs - Details about the High Flow Next LEDs, the RGBpx port, and how to control them is detailed in the Owners Manual, Section 10 which you can download HERE. You control these in Aquasuite, in the High Flow Next RGBpx tab. It's done the same way as any other RGBpx port in Aquasuite. The RGBpx port on the High Flow Next, D5 Next, Quadro, and Octo have some limitations compared to the RGBpx ports on a Farbwerk360, and they are not all the same. The High Flow Next has 10 LEDs built in. The RGBpx port can drive up to 90 LEDs. Since the only power to the High Flow Next is from its USB connection, if you want to drive a lot of LEDs (up to 90 on the RGBpx port) you should plug the High Flow Next USB cable into a USB port that can provide 2 amps of current. In Aquasuite, go to the High Flow Next System tab and enable "Allow USB power supply with up to 2 A.". The Farbwerk360 has Molex power and does not power the RGBpx ports from USB power.

The High Flow Next RGBpx is limited to 8 LED controllers - 2 for the 10 integral LEDs and 6 for the RGBpx port. In comparison, the Farbwerk360 RGBpx has up to 20 LED Controllers and up to 60 Assignments using Multi-Assign. It also has Transparency which is a very powerful feature that allows different effects to be stacked. The effect at the top of the stack takes precedence but by setting a Transparency level, effects lower in the stack can bleed through the effects higher in the stack. I think only the Farbwek360 and Farbwerk Nano have Transparency. The RGBpx ports on the other products have limitations but are fine for doing basic single lighting effects.

I did the same, I used shift on the restart button of the windows login page to find safemode, and uninstalled the program for a minute. :rolleyes:

Thank makes me feel better and you are not the first person who told me this also happened to them. Since this happened, Aquacomputer added the Maintenance Mode. There is an option to cause Aquasuite to start in Maintenance Mode if the PC was shut down 3 times in a row by the Aquacomputer Service. I am not sure if that would stop an Octo Alarm tied to a temp sensor plugged into one of the Octo temp sensor headers. I think when the computer is turned on, the Octo boots up right away and can detect the temp sensors plugged into it without and before Windows and the Aquacomputer service are running, so it could trigger the Alarm but the Aquacomputer service did not cause the PC to shut down, the Octo did.

Note: The Octo Alarm for fan speeds works a little differently than the High Flow Next. With the High Flow, you can pick trigger values for Flow Rate, Water Temp, Water Quality, and the External temp sensor. You can enter a value in the Octo Alarm section for the temp sensors and the flow sensor header, but not for the fans. I tried to test the Alarm cable by activating the Alarm for a fan port, and then stopping that fan. The Alarm did not trigger. What I found is the Octo monitors the fan speeds and compares them to what they should be based on the settings. If you set a fan output to 0, and the fan speed is at 0 RPM, the Alarm will not trigger. If you set the speed to some value, say 50%, and the fan is reporting 0 RPM, the Alarm will trigger. I tested this by setting a fan to 50% then stopping it with my finger. That triggered the Alarm.
