@MrToad: you can already order it in our webshop but delivery will start later around mid March

@churchy: yes, a DDC+ with heatsink is no problem. With waterblock two DDC+ or one D5 together one DDC+ is possible. We were not able to test two D5 pumps since we only have one of it So far I would say it could work but will run at the temperature limits for sure when you try to slow them down.

As said before, the PWM channels can not be used for pumps since they will not run on these channels.
