This is awesome, add one of these to one of their monoblock and it is a godsend.
My only question is, how do one prefill a GPU water block before connecting it without making a mess?

To fill this system (my guess is that it comes dry from the factory) and a gpu, simply use the fill/drain port that you can see on the pump. AFAIK there is no way to pre-fill a EK gpu block.

Well there is a way to pre-fill a gpu block but you would have to have the hosing and the quick connects connected to the block, then fill block and disconnect the quick connect connectors and the loop would stay filled. Then connect it to the system and you would be good to go. Though I would think that they would sell those as accessories as to buy your own (which I have done before) can be upwards of 50 bucks just for the connectors.

If they sold the quick connects that they have pictured for cheap, that would be awesome!
 
I wish I could find a review that addressed some details....

1. How does it handle push / pull ? .... not enuff fan connectors.

2. Aside from the "fill GPU" question how about adding any component ? Drain QD should be at lowest point in the loop, fill point the highest. You wouldn't prefill the GPU, simply tie it in. Then you go to the top fill port (silver thingie in top pic) and fill the loop from there.

3. Problem is, as I see it, that filling and bleeding from same port is cumbersome. The way I would approach filling the loop after adding any component would be to:

a) Take off fill plug
b) Add a G/14 Bitspower C-47 fitting which would transition from the screw threads to a 10mm acylic tube about 12" long.
c) Use a squeeze bottle or funnel to fill tube
d) Run pump using 12V DC power source in short bursts to allow water to drop in and air to get out thru tube. Cost is about $5 for parts not counting DC power source.

This is what I use for DC power for bleeding and leak testing water loops w/o risk of water damage to components.

I routinely use this method on each WC build whether custom loop or Swiftech H-220-X / 240-X series. It works quite well on the Swiftech because of the provided reservoir and Window.

4. Video has fans installed backwards (exhaust) greatly reducing effectiveness of cooling using preheated interior case air for cooling and, in many cases, setting up negative case pressure (unless ya have 5 or more intake fans) which will suck in dust and PSU exhaust heat in thru rear slot grilles.

With 2 ports (fill / bleed), a reservoir window and 6 fan ports, it would be much more attractive.

I have to disagree with you Jack.
Why would you want radiator fans pulling the hot air into your case? And you're talking about dust, which would get pulled into the case through the radiator, unless you put a filter onto the radiator, but at that point im sure making the fans exhaust would perform better than a filtered intake. I'd much rather create some filtered intake fans to bring cold air into my case (that aren't part of the radiator) rather than pulling hot air into the case and hoping i can exhaust it all fast enough.

On top of that, the whole point of these types of coolers is the expectancy that you will be adding your GPU to the cooling system. Meaning that there will really be very little heat being produced inside of the case, so the air in your case should have a delta very close to that of the air in your home. And about the negative pressure, negative pressure is better than positive in my experience. If you have positive pressure, then you end up with hot air being trapped inside of your case also creating dead zones. Where if you have negative pressure, you are getting rid of the hot air and making room for the cooler air to actually flow through your case. The best combination i've used was a good balance of positive and negative pressure, but try and add just a tiny tiny bit more negative pressure so that the hot air actually gets sucked out.

The best example i can think of would be your house in the summer months. Adding just a fan in your window (we're going to assume its colder outside than in your house) will bring in cool air, but it still has to mix with all of the hot air already in your house before it can effectively cool everything. If you then added an exhaust fan on the other side of the house pulling the hot air out one side of the house, and cool air into the other side, you're effectively creating air flow that will cause the cool air to mix around the area faster while removing the hottest air right out of the house so it cannot warm the fresh air as quickly.


I hope that makes sense, and I am not trying to start a flame war, just my two sense

I am considering buying this ek predictor 360. However notice the fans are mounted on top? Pull system

In the instructions it says not to mount fans on bottom of rad Anybody know why?


Also was considering mounting on top of define r5 case. Is this crazy will I loose some cooling ablity?

I have a Corsair AIO liquid cooler, and I'm really loving it. If I ever come up with a reason to add more to the system I suppose this or the 240mm is where I'll head next.
