I am starting to get together a list of parts that i need to build a liquid cooling system, and now i am at the pump. I was looking around and found this http://www.dangerden.com/mall/Pumps/dd12vd4.asp i do realize that the sound level can become quite high but i am going to hook it up to my coolermaster aerogate II, but a rubber pad underneath it, and make a small foam lined box to put in into and drill holes for the tubing. anyone have any ideas or recommendations about this pump and silencing it.

that's a very nice pump but according to tests that i've read, it's nowhere near quiet enough. unsure about reliability as well.

an interesting thing you can do with this pump though is hook it up to a (good quality) fan controller and give it less than 12v for better performance. aussie waterblock designer cathar uses 2 of these pumps in series, both running at 16v, to serve as a "high-pressure" test for his waterblocks.

The DD (DangerDen) pump is not recommended.

Either go for a Swifttech MCP600 ($80 USD) or an IWAKI MD-20RZT ($150 I think and the best of the best for watercooling)

IWAKI:
MD, Jap motors, quieter and overall superior to the USA made WMD type
T, threaded
Z, the high pressure version, do not go for the X, high flow version

Read up on it here:
http://forums.pcper.com/showthread.php?t=327217


At any rate, the MCP600 is just fine for all but the most extreme watercoolers, which is where the IWAKI MD-20Z steps in. If the MCP600 is too expensive, the Danner Mag3 (~$40 USD) is recommended. All other pumps are not recommended (i.e. Ehiem pumps)

If you go for a Danner Mag3, mod it according to this article:

I was looking at the Swifttech MCP600 but from the reviews i have seen it shows it having a low flow rate. will this effect performance any? I was also looking at the IWAKI MD-20RZT pump but i the tubing size is abnormal, how could i use this. I think it is 5/8in

I was looking at www.thehiddenreef.com where they sell IWAKI water pumps. I was looking at them and I cant seem to find the IWAKI MD-20RZT but they do have a MD20RLT which is the pump for pressure applications. Should i get the MD20RLT for pressure applications or the MD20RLXT which is for circulation. Here is the page with all the Japan and American motors. http://www.thehiddenreef.com/saltwater_ ... erpump.htm

Yes and no. Easy rule: when buying an Iwaki for PC watercooling, do not get one that has a "W" or an "X" in the model number.

Yeah it is hard to find the Z model. Whatever do you do, don't get the X. Waterblocks cause a lot of restriction, you want pressure. Sure a pump may have a 300gph lable on it, but that's with zero restiction.

Pumps from Best to Good:

IWAKI MD-20RZT > MD20RLT > MCP600 > Mag3


To be honest, the MCP600 or the Mag3 is just fine for 99% of watercoolers. Another thing to look at is the Wattage. The Mag3 uses like 5 times the wattage the MCP600 pulls so even though the MCP600 is a more expensive, it will actually pay itself off in the long term.

The MCP600 is an excellent choice and will do you proud. :)

Be sure to add sites like pcper.com and procooling.com as you browse forums and read articles enhancing your knowledge on watercooling. I wouldn't even bother checking out other resources for quiet/silence questions though. :wink:

That's a new waterblock for me. You got any review links? Really unique interior design!

no i havent found any reviews yet it just came out like last week. i really dont care about reviews thought because i know it is going to before beautifully. the old polarflo block smoked all the other water blocks and i feel this one will do the same. there should be about a 5 degree difference betwwen the old and the new polarflo waterblocks. or maybe i am just a sucker for chrome and black

Cool deal. Your right, it is indeed one sweet looking WB! :D

I posted a thread about it at pcper.com <here> and emailed one of the waterblock reviewers there. I'm really interested in how this waterblock will stack up compared to its competition. Thanks for the info!

The lack of them is because man is inherently a sinner and most people have chosen to ignore the Lord and have no moral bases to set their actions by other than their God created conscience and the status quo of their culture. :wink:

Indeed. As a science major, evidence of the Creator is simply astounding. Surely such complexity could not happen by chance! We have a responsibility to Him as His creation. Perhaps such responsibility is what induces many to deny Him? We know were sinners and we don't want to have to pay the price, which is ultimately eternal damnation from God. Praise the Lord for his free gift of salvation to all!

amen to that. how can you ignore something that created you and surrounds you every second of your life till you take your last breath and then you go to the creator or the distructor. your actions and decisions in life force you to go one way or the other. i suggest you make wise choices.

double amen. As an elctrical engineering student, people are often surpised when i tell them im a Chrisian. They think that science disproves God, when in actuality it does the oposite. The bible describes evertyhing from the earth being round, the number pi acurate to 5 digits, dinousaurs and even prophecied cars and the re-creation of Israel. I have been blessed to witness a number of miracles. Unfortunately it says that in the last days there will be a famin for the true word of God.

On another topic. Why do you reomend agains Eheim pumps? I thought they were supposed to be good.

Oh, they're not bad, just not the best for the money. They lack the 'head' or pressure of other pumps.

A GPH rating doesn't matter as that is often with zero or a very light load. You want a pump not with a high flow rate at zero load, but with good flow rates in a restrictive environment which waterblocks (some more than others) induce.

If you were using an old Maze design or a Swiffy 6000, then the Eheim is totally fine. But you need a high 'head'/pressure pump for most all modern, more effective designs. And at the price a good Eheim runs for, go for a MCP-600 (or an IWAKI MD-20RZ after lurking eBay awhile lol).
