The question to be asked is, would you get any better temps than with the stock aircoolers... but certainly the MAGII-LE would be enough to adequately cool them to a point of equilibirum within the cards' operating specs. Probably would still beat air, just not allow as much of an OC as the same setup with a stronger pump.
probably with 0% OC i think...
used to run Tt Aquarius3, results almost same as aircooling, not even 5% OC yet...
woot, do you really belive that the difference between mag2 and ddc2 would be that much tempwise with only maze4 gpu and mcw30 in the loop! i dont belive that at all, i think it will beat aircoling with ease and i dont think you would be able to oc that much more with an ddc2...
But if you could proove me wrong id happily get down on my knees and say im sorry!
id personally just modify the Swiftech MCP350.

Although i can't be positive in my opinion, cause i haven't got a personal experience. I too believe that a DDC won't yield in significantly lower temps and higher oc's. My :2cents:Quote:

I couldn't agree more! My experience with watercooling (5 years) shows that a 1c difference in gpu temps only results in about 1-2 mhz increase in o/c (using atitool)Quote:

i own a csp mag (the old square style running 24/7 have owned it about 9 months it cools a prescott 3.4 @ 4.1 with 1.55 volts and a 1900xtx @750/840
and has no problem keeping things cool and as far as noise my enermax liberty psu is the only part of my pc you can hear( except for drives when active). it is rare for my temp to get to 50c. i can post screens if needed.
i think the new style should do even better and wouldn't hesitate to get one.
by the way mine seems to have much more pressure than the one shown pumping into the sink??? maybe i just got a good one.
Hello.
Could someone please upload the pics again? :D PLEASE!!!

I do.Quote:

Think i will try out this pump(if Quoc havent already packed my rather large order), helluwa lot better than my L20 atleast, Then i can switch to ddc-2 petra later...(with storm)
I have orderet it and looking forward to get my water running! So I can OC my Conroe more, im at 3100-3200mhz @ standart voltage and boxcooler.
But if the pics. could be uploaded again I would be very happy! Together with others im sure :)

Taking notes... so far from 12 sold out of last batch received, 4 have been returned for same fault - no pumping, loud whine being emitted.Quote:
None of this says anything about reliability, though... that takes a very large sample to determine (i.e. numerous pumps).
Right away or dying after short usage?
Bit o' both. 2 were DoA. T'other 2 died within 48hrs.
Marci, are you talking about the Danger Den pump? Could it die very fast? And what are the odds for a working one?
I'm talking about the pump that shares it's name with this threads' title. Odds are shown above based on the small cross-section I've come across.
Okay.. I hope my one will live long time:D
It should be here tomorrow.
No DD pump i've seen of recent is lasting as long as it should!!! Shocking
Nothing new... s'just following the usual trend of high failures in pumps manufactured by C-Systems...
I don't think so. Pump power is only important if you want the max. Performance from your system. A D5 has nearly double the flowrate in a normal loop, but that doesn't helpscooling that much. A old waterblock like a maze4 with a strong pump like a D5 performs worse that a modern waterblock like a nexxos xp with a small pump like the Mag 2 LE. If you have blocks without any turbulence increasing structure, jets or pins, you actually won't be able to spot the difference of the pumps. With better scaling waterblocks like Nexxos, Storm, etc. you will notice a few minor degrees.Quote:

As the D5 is only slightly better than the aquaextreme 50Z. So with a Storm G5 and 71Watt of heat output, you could expect about 1°K difference between these Pumps. Well since cooling is linear, you could say that even with a modern overclocked 140Watts CPU and a extremely well scaling block, you won't get much more than 2°K difference.
And Marci, don't tell me that 2°K harms Overclocking the sightest bit, i don't believe that.
Biggest problem with this pump is in my opinion, that it isn't a proven design like DDC or eheim pumps. Eheims design is tens of years old and proved to be longliving while laing transfered their firing pump experiences into a well thought design. Compared to that these brushless dc controller pumps which adapt the electronics of common Fans are not proven in any way. I expect them to have a failure rate quite ahead of the other proven pumps. But when that has sorted out they are ceratinly a very good cheapo alternative.
Well, one thing you didn't take into consideration, when talking about the differences, is radiator performance. If you take a look at the tests that were done there, radiators do scale just like modern impingment blocks with higher flow rates, which then would double the performance difference between the very weak and the very strong pump. So then, if you continue to optimize every little bit of your cooling setup, you'd have more than a considerable performance difference :)
