Mine came in yesterday as well w/ 1/2" barbs.
These pumps sure deliver for their size. amazing ! |
Thanks for the heads up Dave, ill be sure to contact you if I have any issues.

The extra head in series is adding extra head (froth) to my loop. That's something I didn't have before at all but I suppose it's ok. Temps are down about 2c that I can tell so far but sometimes after a few days of running it it improves. |

Ok, got one hooked up to see what they can do. These guys arnt kidding about the noise, I had to get closer than 30cm to hear anything, outside of that they are totally inaudable. Seems to have a good flowrate, I think it's almost funny how a full size Danger Den Maze4 GPU block is almost as big as a single MAG. My Noise Isolator fan controller had no issues controlling the flow rate of the mag. So far these little pumps look like winners :) Pictured here is: HW Labs Black Ice Xtreme rad with 1/2 fittings DD TDX 3/8 for Athlon64 DD Maze4 GPU, Delrin low profile top, 3/8 Dtek CSP-MAG (1 of 2) with 3/8, Rear inlet. Angel Eyes Bayres, 3/8 (complete with giant stain from Water Wetter :( ) Generic 3/8id 1/2od tubing (will be tygon on the real loop) Water with a few drops of yellow food dye. |
I'm running 2.5gh @ 1.95v on my 3000+/400 barton. So far so good!
I was 2.4 @ 1.825v but temps wouldn't let me get any higher ...now my temps are what they were before the extra 100mhz. |

heh yeah, kind of does look like whiz doenst it :D i assure you its not.
As for RPM i have no idea, the mag seemed to handle the voltage change with no issues. As far as I know Rear inlet is what i have according to DTek, top inlet being next to the typical top outlet. |
Nice! I just hope that they last. :)

MAG's run at LOW rpm, around 2400-3000.
Help keeps noise down and extend pump life. It is a low speed / high torque motor, as opposed to DDC, high speed / low torque. In other words like Dan likes to say, MAG is an old V8, and DDC is a 16 value straight 4, both hit 1/4 mile at same time. Which is better approach? We can argue that for years, can only say MAG needs high starting torque because OEM versions often pump higher viscosity fluids. (This does not mean you can do the same with retail model) As tech and support rep, must say additives void warranty. As fellow cooling enthusiast must say food dye is fine, but you need a different color :) |
"Nice! I just hope that they last."
Not starting an argument Max, but worse case, bearings or shaft ware down.... and the "big secret" is out, MAG runs fine without any bearings. Yes, several people figured it out already, the rotor can run in magnetic suspension, fluid stabilized. Bearings are there to stop, start up / shut down noise and to help boost flow. Of course like any pump, you can still overload the electrical components, by using higher viscosity fluids, or stopping impeller. We would know when examined, if this happened, as we have overload indications on circuit board now. Just some info for you Max, as I am at C-systems again with nothing to do. Most of the staff has been away all week and didn’t leave me approval for anything. |
dave quick question 4 ya how hard wud it be to make a twin headed mag ie 1 motor with 1 pumping head ither side runin on same shaft for ppl who are mental and ppl who wud like to run a seprate gpu loop
tnx 4 time |
Not hard I guess, but people are discovering thanks to guys like Cather, massive increases in flow does not equal higher performance.
Not sure it would save much space flat, there isn't much space wasted. Maybe 1/4-1/2" smaller then two pumps. Also guys, place 3 in series will not help head, we design impeller / rotor to max at specific rpm. We have to do this because people are "modding" pumps and we had to find a way around this and make our insurance carrier happy. For those that do not understand pumps / motors let me explain. If you design a motor / pump to run at high RPM, forcing the motor to run low RPM will overload it. When people "mod" a pump chamber, you increase flow, which DECREASES rpm, and therefore increases load. Our solution was a tuned rotor / stator combo that doesn't allow any increase in performance by "modding" the chamber. You can increase outlet size, or inlet, and true system flow will decrease. So place two MAG's in series you will get about 6 psi, 3 MAG's will only get you about 7-8 psi, and so on. When we figure how to change the higher RPM pump so we can tell if it has been modded, we will release it. Until then, higher head pump is OEM only :( |
thankyou for you swift responce and comments
i was personaly thinking seprate loops for cpu and fx/np and haveing the bonus of added flow the rad interesting point on mod's and shutch maybe a "void if removed" sticker and a modabull pump may make "us" dremmal deamons happy :) tnx again |
^ Can't do that, we all know some people may have to clean out there system, including the pump.
If there was a simple answer, Laing or one of there distributers would have done it as well. We are trying very sensitive current monitoring circuits with not much luck :( The problem is not modding our chamber, it is companies that make modified chambers that fit right onto orginal drive, like they do with the DDC. Nothing to do, heading over to AVT an work on C-Systems tooling. See all next weekend. |
Can 2 pumps be placed in series back to back ...and two of those sets of series pumps be placed parallel to give double flow to a double head loop? In essence you would have 4 pumps total in the loop.
Someone is talking about doing this in another forum with a sketch included. |
You can place as many in series as you wish, all I am saying is each pump add's less head, there is a limit to how much head pumps in series will produce.
4 Mags? Why don't they just try one, then two and observe temps? If you want that much head / flow, there are much better pumps out there for this range. Two of the new D5's will do well. I think there wasting there money, but if you want to spend that much for an extra 0.5Deg C, go ahead. Would be cheaper to buy an air conditioner and sit it next too your Rad :p (Keep you cool in summer as well) |
Seems to me like a matter of trying to get massive flow with minimal acoustics, ignoring the price : performance ratio.

New question-
How do these pumps handle operating without liquid in them? I know with the fluid suspended impeller design like the Hydor L20 dont fair so well, and I know this because I had a slight accident which resulted in my L20 running with nothing in it for about a half hour straight, from then on it rattled, and looking at the impeller the magnet core was chewed up pretty bad as well. Obvioulsy the mag doesnt follow the same design, but I am just curious if these can be irreperably damaged by running without any liquid flow. You guys suppose this might be a good sticky? Seems to be the CSP-Mag/C-Systems thread of choice :) |
Dave,
Can you estimate what the head and flow rate would be with the following setup, 4 total pumps consisting of 2 sets (of 2 in series) in parrallel ? Code:
,,,, Pump 1 + Pump 2 ,,,, |
Approx. slighty less than twice the head and twice the flowrate ;)

Not sure Brit, depends on back pressure.
Der- Some Mags run fine without fluid, some have high end vibration, depends on final balance. The fluid stops this vibration, hence "fluid stabilized" comment. Running MAG open for short time is fine, long term can causes bearings to crack. It is best to not run dry, if possible. I did run a MAG for over a week dry, didn't know the damn thing was on. I sent the address to sales for the review pumps. All the sales staff was away last week, for training. There are new customs rules and procedures for US shipments now. I am no longer to ship direct anymore, but will ask what went out. Off to work, later all |
Top inlet or Rear inlet?
I have two gorked 750 MKIIs I want to upgrade, but on visiting the C-Systems website I'm given the option of Top inlet or Rear inlet designs. However the pictures for both are identical and I can't tell for certain from anything else on the website which is which and what the geometry of the two different versions really is. It also seems the MAG pump pages are cut and past inserts into the old 750 pages and that some of the stuff on there has nothing to do with the Mag pumps.
Somebody needs to go through and edit your site and bring it up to date. Hoping for clarity. random |
rear inlet..

Dave, could you please to light this doubt. And, please, ask Julie to change C-Systems page picture (are both T and R same)... http://img215.echo.cx/img215/7775/magrotulo2uw.jpg http://img231.echo.cx/img231/5320/mag013tw.jpg |
^ Thats is just a customs label, does'nt matter if R or T, same price.
Or are you suggesting you ordered an R, and got a T model? Let me know if someone made a mistake. Dave *Is long weekend in Canada, will not be in tomorrow. |

Notice that C-Systems' homepage pictures are identical. I'm suggesting to make it clear with true pictures. Editing: some in Brazil are asking me about which is better T or R, asking me for testing my unit and how they could be sure about right model, since both pictures are same, at C-Systems' site. Ok, if here it is impossible to get simple answer (like THIS is T, and THIS is R) i will contact C-Systems directly. Thanks, anyway... |
