Another DDC top comparison

post #1 of 6
Thread Starter 
A bit late to post this one since it was published at the end of March, but better late than never here. I have a feeling I already posted this somewhere but I hope not since search came up empty. redface.gif

Feel free to use your preferred translator for this, but to get down to the results, starting with flowrates in liters per hour at full pumping power:

and here at half power:

and comparing how much noise the tops add:

Great showing from EK as is typical of these German tests, though Koolance and Watercool surprised me especially considering Watercool's top used to get low performance scores. The only mark I can put against the testing is no pressure comparison, I suppose.

Happy now? tongue.gif


You are right in that it could do with some pressure readings to be meaningful. Saying that the ball valve was 100% open and 50% open and running through their test system doesn't really translate well to any individual loop, but at least it shows ballpark figures.

Koolance top is the winner??
I was told KL's tops are not good since they are designed as a res base...
post #4 of 6
I had a hard time following their test methodology, but it sounded like (Crappy translation), that they may have tested in an actual system and the % was simply an additional valve they closed partially.

100% represented no valve restriction (Wide Open or Lower Restriction)
50% represented the valve closed half way (Half Open or High Restriction)

As far as I know Koolance doesn't make the "AC" top anymore, but it looks like that may have been a better design than the current model.

I am a bit surprised at some of the results though.

Skinnee is very meticulous about his testing and this is what he got. You should focus on the 1.0 to 2.0GPM range (That's the only part that really matters since that's where restriction normally falls):

From the above it looked like the Watercool and XSPC tops were pretty close and EK top following a touch...either way very close.

Hey, know what? Flowrate-wise that comes almost close enough to verify the results at Awardfabrik, though they didn't do the Bitspower unit. Too bad they didn't pressure-test...

Also don't forget the DIY Vapor mod, it performs really well. I'd like to try it myself sometime just for fun..

A very good DIY project that gets you top end performance.
