Questions on adding Octo to Aquaero

Thursday, May 14th 2020, 11:04pm

I was successful adding my new Octo to the aquabus on the aquaero 6 LT. I updated the FW on the Octo and have both the aquabus connected and the USB connected. One question is that I noticed the Voltage on Fan 5 which is the first fan header on the octo did not decrease in voltage as I decreased the power input after connecting a fan. Shouldn't the voltage decrease or is it locked at 100% because it's controlled via the Aquabus? I have attached a picture of the difference between Fan 4 on the Aquaero (which does decrease voltage with decrease input power) and Fan 5 on the Octo. Second, the update service expires 11/14/20? Only 6 months for this device? Is that correct? Thanks.





Note the other 2 devices are the Aquaero and the MPS flow meter.

The OCTO only does PWM, it does not do voltage control.
First sentence on the OCTO product page:

Quoted

The OCTO made by Aqua Computer is an eight channel PWM fan controller

I believe you are good until 8/17/2021 for your aquasuite license... it updates to the furthest out date.

Ah, yes. I see. I’m used to seeing the voltage input decline on the aquaero as I decrease the power control. I did notice you can decrease the voltage on the controller tab of the aquaero but it decreases the voltages to all the fan inputs simultaneously.

So I will be ok on the license/software for all devices despite the dates I’m seeing. Thanks. That was a bit confusing. Appreciate the help!

Yes, it will adjust the output of the fan port(s) you assign to that controller, and consequently all fans attached to that fan port.
If you wish to run some of the fans at a different RPM, they should be on a separate fan port, and then make a 2nd controller for that fan port.

Are you running 3 pin voltage control fans on the OCTO?
If so, you will not be able to control them, they will run 100% all the time.

No. They are 4 pin PWM fans. Thanks again!
