The DDC3.2 is rated for Nominal Power (@ 12 V) 14 to 19W and Nominal Current (@ 12 V) 1.16 to 1.58A according to Swiftech.

The Aquaero 5 is rated for 1.65A/channel, maximum power is dynamically limited through temperature monitoring.

What concerns me is the description for the PowerAdjust 2:
"The poweradjust 2 is primarily optimized for the control of Laing DDC pumps, but also other consumers with up to 25W continuous power at 12 volts can be connected to the controller."

So, is the Aquaero 5 LT capable of running a DDC3.2 plus around 5 fans or not? Startup amperage for the DDC will be higher than “nominal”, but I don’t know by how much. My Aquaero will have the aluminum heatsink and sit right behind an intake fan so it should have decent cooling for the VRMs.

The fans are rated at 0.30A each (1.5A total), the DDC3.2 at 1.6A. That’s a total of 3.1 A for everything. Do I need to be concerned or will the Aquaero 5 drive all that without issue? I can hook the pump to a different (manual) controller, but I’d rather remove that entirely and run everything through the Aquaero if possible.

Is a good question, if the AQ5 can handle 12W( 1 amp) with aluminum heat sink / channel

Where did you get that spec? Documentation I can find says 20 watts per channel, but dynamically controlled for heat considerations. It doesn't say anything about what to expect with what cooling.
