The temperatures shown are the difference calculated from CPU-Temperature minus Water-Temperautre.
CPU-Temperatures are under full load (Everest stress test), measured and averaged out during a 20 minute time frame, after a 45 minute warmup.
The ambient temperature (more precisely the temperature of the air moving through the radiator) was between 21° Celcius and 22.55° Celcius during the test runs.
Hope this answers your questions. :-)
I am confused, isn't the 1T the MCP350.Quote:
Laing DDC 1T+ (Swiftech MCP355)
The Laing DDC-1 plus is the MCP355 innit?
Or is this a regional thing.
I thought it was:Quote:

But I'm not sure. Memorizing cryptic product descriptions isn't one of my strengths. :-)
I got an Update for you guys:
As promised, I wanted to see if I could reach those 2 GPM everyone goes on about here. ;-)
So, I installed one of these:

I also tightened up the loop as far as I could, what with the ball valve, temperature-sensor and flowmeter needing to be in there. Result:

And what did this effort and a dual-pump top with two MCP355 achieve?
* drumroll *
... about 1.2 GPM. :(
Still far from 2 GPM.
I'll post the data from the test-run anyway. Tomorrow. I'll have to make a pretty graph or something, first.
Who makes that, and where did you get it? Every double pump top I've seen has always had one DDC on the bottom and one on the top, not side by side like that. I'm currently trying to figure out how to cram my dual pumps into my case (which is very quickly running out of usable room), connect them to each other, and not kink my tubing all at the same time. One of those would go a long way towards fixing that problem (although I'd want it made out of Delrin or similar, I don't want any acrylic in my build).
It's made by Watercool, a German company. I got it from Aquatuning, a German online store. No idea if or where it's available internationally. The acrylic version is the only one available, so far.

wow does that mean two 355s with reservoir tops in series won't reach 2gpm?
adding a second ddc increases head pressure far more than in it increases the flow rate
Giannis
does it really increase head pressure? where do you base your statement?
Just out of interest, try them in parallel. ;)
That dual top might not be the best candidate for the testing.Quote:

have you tried it with two res tops on the 355 + ek supreme + 2 rads?
its says 2.09gpm
but i dunno if thats tested or not..its theoretical..but not proven...
thats why i'm suggesting to Hes to try it
what do you suggest other than the iwaki?
First of all, here's the data:
I measured temperatures with the same methods described in above posts. The setup reached a maximum of 1.19 GPM and I also measured temperatures in this same setup at 0.92 GPM and 0.66 GPM.
http://shane.seraph.ch/GraphHighflow.jpg
Clearly, the downward-trend in temperatures continues with increased flow-rates. Between 0.66 GPM and 1.19 GPM, temperatures dropped by about half a degree. Also very interesting to see: The added benefit of higher flowrates is greater than the drawback of an extra pump dumping it's heat into the loop - the temperatures at 1.19 GPM were the best I'd seen in all of the test-runs.
Considering further testing:
The loop pictured above will be disassembled today, since there is other testing, that needs to be done. I'm testing some pump tops, among them one or two that even you at XS might have not seen yet. :-)
After those tests, I might find some time to chase 2 GPM again.
Question: If I use two pumps with res tops in a loop, won't one of the reservoirs overflow?
yes the second will overflow...i used teflon tape to seal my second pump..i bought the non res top so it won't overflow for the third pump...if you look at the picture i posted
Thanks for the info. I might just try to use one res top and one non res top, then.
have you tried this at all? even with martins flow calculator your suggestion fails 1.8gpm :down:Quote:

It's true, we Germans don't give a rat's ass about flow rates. And why should we, spending a lot of money for like 2-3C less with lots of additional noise is totally not worth it.
I run 2 EK Supremes, 2 big Rads, the HDDs and raidcon with around 60cm flow height and ~3m tubing length on a single Aquastream XT pump in one loop, that's probably not even 0,2gpm. Still I don't get more than 50C Coretemp on either CPU :p:
You want better temps? Run phase.. that's what I do, anyway. Water is for good yet silent cooling, it's not about 2GPM+ flowrates.
You people will realize that soon enough :p:
Oh yeah, really nice testing there.
The same people who insist on 600/700/800 lb. ft. of torque and 500/600 hp in a family passenger car, or even station wagon/estate, prefer 0.2 GPM pumps lol How strange this world is. :yepp:
