I Choo-Choo-Choose you!(DDC or D5?)

[Senseless]

Mapping out my very first custom loop!
This will be a CPU only loop to cool whoever wins the 7740k vs. ryzen showdown in a few weeks. 95w+, so let's say 145watts to be safe.

I'll be using EK everything for aesthetic and local availability purposes. I'm sure bitspower and others make some great stuff, but i can pick up emergency ek fittings from my local store in a pinch.

Corsair Air 740
front mounted EK-CoolStream SE 360 (Slim Triple)
EK-Supremacy EVO block (will wait to buy until cpu compatibility is confirmed or model updated)
6 compression fittings minimum, possibly 8. Can't plan my drain port until i have pump dimensions.

TLDR- DDC vs D5 in this use case?
Really want to do a pump/res combo unit. Can they be mounted horizontally?
What's my real ideal flow rate here?

Just get the D5, it's the better pump

D5 when space is not a factor. Its not in the 740.

 

[BigDaddyKong]

D5 all the way.

You want to aim for 1GPM (gallon per minute) and the pumps these days easily achieve this without trying. The only way to push a pump to its limits is to go completely overkill on rotary fittings. Even then it is hard to do if you are going down the DDC or D5 route.
