Hi....the double ddc top actually houses two siphons, with independent cabling. What you do is join the force connector for both to an ordinary 4-pin enormous molex connector from your psu.

Then, at that point you get a 4-pin splitter link so you can join the two siphons to one (of the four) fan headers on the aquaero 6. What's more, in the aquaero programming, select pwm control for that fan header. Ensure just one siphon convey the speed message to the aquaero however, or you will get out of place speed readings. Yet, most, if not all, splitter links just have the speed signal joined to one of the male connectors.

You could likewise then again utilize one fan header for each siphon, that would in any case leave you with two headers for fans and so on
