Cool thats good thanks. I just noticed that it only has a single pwm channel.It does store the configuration so that it can run completely autonomously. You can configure them without the software if you have the version with a screen but it's a bit more fiddly.
The can do an emergency shut down in a couple of ways:
It can present a zero rpm signal to a motherboard fan header so that the motherboard's bios shuts down the PC (when configure to do so).
It has a couple of relay outputs and I believe there is a separately available cable that plugs into the ATX cable so that the Aquaero can basically hold down the power button until the PSU turns off.
Edit: Apparently you need "Plug for relay connector, 3 contacts (for aquaero 5 and 6)" and "aquaero power connect - 24 pin ATX standby power / ATX break"
I have 8 pwm fans that I don't mind running at the same speed but I also have a pwm pump. Can the pump be controlled on a different header at all, or am I out of luck?
I can't spring for the 6 XT even if I wanted to as this is going in a h440 with no bays for it.
