I'm starting up a new watercooling setup and am wondering about quiet pumps.

I've heard that the Swiftech MCP350 is a decent pump for sound, however I've also recently heard that the DD CSP-MAG is a very quiet option. The other options I was thinking of were Swiftech's MCP600 or MCP650 pumps.

If you would be so kind to give me advice on which of the above would fit the goal of silent overclocking, I would much appreciate it.

Thanks for the help,

Rob

Ok here we go.

Swiftech MCP350 ( AKA Laing DDC) : This pump is a very nice, very small pump. It has excellent head pressure and decent flow. It is natively 3/8" and is probably best suited for moderate flow loops which are using 3/8" tubing, or setup's where space is at a premium.

DD CSP-MAG : This is a nice little pump, supposedly quiet. The first few generations of this pump had notorious failure problems, but those seem to have been ironed out. This is probably the weakest of the pumps you have selected.

Swiftech MCP600 ( AKA AquaXtreme 50Z) : This pump is no longer commercially available ( the mcp600 that is). Swiftech stopped carrying it due to a defect in the pumps. However Cooltechnica now stocks a revised version which solved the reliability issues, and calls it the AquaXtreme 50Z. This is a great pump, with excellent performance characteristics. It is also relatively quiet, making it a very nice choice.

Swiftech MCP650 ( AKA Laing D4 ) : This pump is the one which replaced the MCP600. This is slightly more powerful than the MCP600, but it is notoriously noisy. Some of the units are pretty quiet, while others have a problem with an annoying whining sound. I would not get the MCP650 (Laing D4) if I were you.


I am also going to throw in another pump which you left off.

Laing D5 ( AKA Swiftech MCP655 or DD-D5 ) : This pump is the successor to the D4 (mcp600). It has solved the noise problems, and this pump is very quiet. The performance is largely the same, and is probably the best performing DC pump you can get. The D5 also has a very nice feature, a potentiometer which allows you to adjust the speed (and noise) according to your needs. Obviously the higher you set the speed the more noise it makes, but even on the highest setting it is pretty quiet.


Depending upon what type of components you are planning on getting I would recommend either the AquaXtreme50Z or the D5...perhaps the DDC.
 
The ones you picked are all noisy. Only difference is the degree to which you know of for reference. Listen to an Aqua Computer or Innovatek 12 volt modified Eheim 1046 or even a regular 1046 pump and you will understand what silent is truly about. If you want quiet then a DDC would probably suffice, but it definitely will not be silent.
 
Well, I'm trying to balance performance with quiet. I'm fed up with my current system, which is abhorrently noisy, and I'm assuming that the pump will be quieter than the combined noise of the GPU stock fan + CPU fan.

If I could get truly silent with heavy overclocking potential, that would be nice, if not, I'd settle for quiet with good performance.
 
Silent with good OC potential is within the range of just about any high-end system you would buy around here. Just depends on how much you want to spend and how important looks are to you. We just need to know your budget, computer hardware, and the case you are going to use.
 
Budget is somewhat flexible, although I would like to keep it as cheap as possible.

I have a lead on two swiftech blocks, the MCW5000-64 CPU block and MCW50 GPU block, for a very good price. The person who would be selling me those also has the pumps I mentioned in my first post, which is why I mentioned them.

It would be a 3/8" system, case uncertain but at least midtower, possibly full or server (I have several..seven actually.. in my bedroom currently).

The other option of course would be going to an entire 1/2" system, however then I would have to spend a fair bit more money I would think on blocks than I can through this person.

Basic specs for system would be as follows:
A64 3200+ or Opteron 144/146 depending on availability (possibly SD 3700+)
2x512mb Crucial Ballistix
X800GTO unlocked to XT
Either Asrock's ULi chipset mobo or Jetway's SLI (both got very good reviews over at Anandtech and seem to be very good alternatives to DFI's lanparty series, although the Ultra-D could be a consideration)

From what I understand, the Northbridge does NOT need water to hit very nice speeds on any of these boards, so I'm not concerned about that.

Edit: In addition, I was thinking of perhaps running dual rads with a massive res in a seperate case and putting some holes in the first (system) case, so as you can see, size and beauty aren't necessarily my top priorities (although I bet I could make that a *VERY* clean mod).

That really is strange TN... cause my DDC runs silent as a ghost. Theres no way you'd ever hear it running over the sound of even one 12cm fan at 7v. Hell, you can barely hear it with nothing else on. Maybee if it had AC stamped on it?

With waht your talking about, I would probly go with the DDC. It matches up with those blocks really well, its small, and relatively powerful.

Actually AC does sell the DDC and still is not silent. ;)
 
In my opinion the Laing DDC is the single best option when you're considering noise/features aspect and works great in 3/8" loops and 1/4" loops aswell.
The Eheim's are old-fashion pumps, like bricks (wasted space), lots of volume but very little head, EMI interference which implies spending more cash in a cage, the parts (impeller;shaft) wear.
The difference in terms of noise between the two is so small, that all the disadvantages acquire a much greater importance.
 
The MCP655 is quiet enough for me even @ highest settings compared to what i was used to with all my fans running. Its not going to be totally quiet , but you can tune it down to your liking. Has a relatively small footprint too. Seems pretty powerfull as well.
 
I got a similar problem. But with a twist.
I'm planning a WC system with 2 splits (one cools GPU+HD's and the other CPU+NB). To keep the flow I either go to a powerfull pump like a eheim 1250 or 2 smaller ones (1 for each split like a eheim 1046.
The question is: is it worth it (the 2 splits) and what is the best balance noise/flow (1 big or 2 small)?

If you don't get a defective one, the CSP-MAG is quiet... I don't know how you can describe it as noisy. I guess a 1046 would be quieter, but even with noise, you have the law of diminishing returns. On the other hand, I probably would not recommend the CSP-MAG since I had problems with noise the first week, although the noise has gone away (Something about the impeller manufacturing process IIRC)

According to TN the noise chart goes like this : Absolutely silent - Noisy - OMGWTF get that jet engine away from me

If it isn't absolutely silent then apparently it is noisy :rolleyes: Almost all of the pumps mentioned are quiet pumps, with the exception of the D4 (for the most part, some D4 are very quiet).
 
silent (can't really hear up even up close) - Aquastream, 1046/8

quiet (can just hear it up close, barely/not noticeable from a meter away) - L30, 1250

quite quiet (can hear it up close, noticeable from a meter away, from 3 meters... barely/not noticeable) - DDC, D5 @ 3 (just, imo)

noisy (can hear it up close, noticeable from a meter away, from 3 meters... still noticeable) - CSP750 (i've got 2, both are like this - bought at different times and from different vendors, maybe both are defective?)

very noisy (can hear it any where and every where!!) - D4

Before anyone has a riot and flames regarding these... I guess I better state in writing and in bold that these are my personal opinions of using these devices in situ. i.e. inside a case with the case door open and with plenty of padding.

I'm all about silence rather than performance, so I take noise pollution more seriously... and all my pumps have been and will be padded and vibration damped to hell and back to reduce noise further... and you can consider that the pumps will be the only noise around as my fans are HDDs are packed and configured as such that they are barely/not noticeable even right up close.
 
I have a new DDC CSP mag with a 120mm Pabst and Antec powersupple and all I can say is the pump is the quietest part of the setup, if you can dampen the vibration you cant hear it at all but I havent done that in a permanent manner yet. The hard drives are incredible annoying now because you cant hear anything else.
 
Thus far I'm leaning towards the Swiftech MCP350, due to ease of acquisition (financially and otherwise) and seemingly positive sentiment.

If anyone would like to dissuade me, now would be the time to make your closing arguments.

Thanks again for all the information

Silent

Quiet

Noisy and get that POS out of my house. ;)

I want to listen to Yanni without hearing my computer in the background. :D

i cant hear my D5 from any distance unless its vibrating against somthing, and thats what the rubber washers are for, maybe i dont get any noise max flow because i have a verry unrestrictive setup, and people are listening to them hooked up to say the storm block or not pushing through 1/2 inch ID? basically with the case door closed(who will have there case open when they have water cooling anyway) there is absolutly no noise other then the sound of the air going through my radiator which is so faint you need to have your head next to it

people complain about being able to hear there baracudas, there silent for me, even durring heavy seek, its actualy a bad thing because i dont know if the hdds are doing heavy seeking or if the game or w/e hung on me, i have to physically feel the hdds to feel the seeking, and i did nothing to isolate the hdds, ones screwed to metal the others zip tied to the other hdd piggyback style

maybe my case has so much mass to it that it soaks up sound like a sponge? i dont know, i just know just about every laptop is loud compared to my pc and my rooms quiet enough to hear the stupid ringing noise you hear when there is no noise :mad:
