My particular issue was the actual "Cap", the little black plastic cap threading wasn't sealing right for me. This was probably only an issue for me because I also had a big test reservoir feeding the reservoir, so my loop had two openings and because this one wasn't sealing for me static water pressure from the taller reservoir was pushing a drop of water out of the cap when tilted over. The issue with mine I think is hopefully just a fluke, but the acrylic threads weren't deep enough to prevent the cap plastic threading to have enough strength. In a real water cooling loop, having the reservoir cap perfectly sealed isn't that critical if its upright. My own system I don't leave this sealed perfectly because I like a little venting capability. It seems like the system warming and cooling down does enough expansion and contraction to where a little opening to the atmosphere is probably good.Originally Posted by Jupiler
Thanks for sharing the results Martin.
About the XSPC res top :
In your conclusion, you stated that you had problems sealing the reservoir and you used the XSPC barbs.
Does this mean that someone would have the same problem if they used EK or DD barbs?
Or would using a bigger O-ring solve this?
Does this apply to the XSPC Laing DDC Top too?
Anyhow, my sample was previously tested, so it's possible I just had a slightly damaged thread from the previous user.
The barb threads and everything else was fine, just the little sealing issue on the res cap.
I think one of my DDC2's is actually a DDC1, but that's probably going to be a little different result.Thanks for the great work and an interesting reed!
I would love to some results from a testing with the Laing 3.1 10w
While you could find tests on the internet done with the Laing 3.2 18w
It's almost impossible to find tests done with the weaker Laing 3.1 10w
The results I'd be most interested in, would be the results between the
'Alphacool top' and the 'XSPC top'
I'm really interested to know how XSPC top hold's up with the Laing 10w
And do you think that the Alphacool top would do a little better
against the rest of the tops with the Laing 3.1 /1-T 10w
Not only I bought the the inferior Laing pump! I also choosed the worst top!
I could test a DDC3.1 if I had one, but I don't. I could probably undervolt my DDC3.2 to simulate a 3.1 though...hmmm
Yes, I only tested the Koolance top and the DD top with the inlet barb centered over the rotor to eliminate the 90 degree bend. Reintroducing the 90 degree bend on the inlet by using the side inlets can be seen by looking at the alphacool regular top to reservoir top results. It would give you a little boost in pressure for extremely restrictive systems, but it would also hurt flow quite a bit and do much worse for average to low restriciton systems.Awesome work yet again Martin.
I have a question about the Koolance notes though. You say
By "center inlet", am I correct in guessing that you mean over the rotor? Also, what exactly does "large step loss in dual outlet" mean? I already have one of these tops and I may need to put it on a 3.1 and into a shiates & giggles aluminum loop I'm building if my CSP-mag ever goes bad.
Just noticed you misspelled "dual" in the above.
The large step loss I mean is the Koolance top outlet threading hole. It intersects the normal outlet and creats a pretty sharp and big cavity that likely adds some loss there. Koolance used pretty big ports so when they created dual inlet and dual outlet options, it creates some added restriction. Pumps for some reason are even more sensetive to little restrictions than other parts of the loop.
Fixed the dual, thanks!
All of the tops did really well, I consider them all a very very good improvement over the stock pump top...

but the results would be hailed as a holy script
