Alphacool Eisdecke D5 Dual Plexi Top (13312)

Excellent build quality. Lot bigger, heavier, and sturdier than I expected. Important stuff to note below:-There is no instruction manual, so study it a bit before you regret it after installing. It puzzled me a bit.-The shortest screws are not for your D5 pump bracket. Use the longer one.-Comes with a few port plugs in case you don't need to use those ports.-Comes with some weird prying flat- & oval-shaped tool that I have no clue what it's for.-Not mentioned clearly in the description, but it has two RGB connectors and they are very thick, durable rubber cables.

Pros:- The form factor and connection placement is very functional.- Aesthetics are great.Cons:- The plastic is forming many micro cracks over time.- The screws are too cheap. Made of a horrible soft metal. Don't properly fit any standard imperial or metric Allen wrenches; I have many full sets. I'm excellent with screws and I've had to speed-out and throw 3 of these so far.- The flow geometry is crude, especially around the impeller; it is unoptimized and overly simple. The flow rate is ok when primed but could probably be a lot better. The flow rate while filling, when there is any air mixed in, is horrendous. Filling a loop is a nightmare, like no other pump topper I've used.- The channel diameter is too small.

Great quality.I was able to take out my 2 d5 pumps from my previous set up and attach them to this. No problem. No leaks.RGB is what you expect. Handful of colors. 4 pin rgb.I use it for my 4 radiator setup and it handles it like a champ. Would definitely recommend this if you have a lot of Rads.
