Choosing The Best Pump for Your WaterCooling System

[shachar2]

same thing as in choosing a computer only you can give guidelines like: if you don't buy the computer for gaming don't invest in a good HD. if you plan to save a lot of video or HD images get a big HD. if you're worried about your data do a raid

Sorry to be rude, but if you find the stickies useless, then go look elsewhere or write us some good ones. Go ask your dad to pay you a private consultant that can choose for you a pump since you seem unable to make any decision by yourself

My last answer to you (another stubborn on the ignore list).

PS: when you answer others' posts, take the time to read and think before writing useless answers (in regard to some of your posts in other topics, heh)

My swiftech 350 burned out today. I'm going to get an iwaki, but I don't know what to do about the barb sizes. I have a 3/8" loop, but I'm looking at the 20RLT and that uses 3/4" hose hookups. How do I convert, and can I go so low as 3/8" without causing the pump to stop functioning? I could also get a 30RLT or 40RLT at the store I'm going to, but they cost more. Would it be worth the extra money to get these pumps over the 20RLT?

I also don't have a res. does a pump this big need one to keep the pressure manageable?

Those pump models have NPT threaded connections not hose barbs, you can easily get the correct adapter from McMaster.

Go with the RD-30 and Meanwell S-150-24.... FTW

Do all the iwaki's need a 24v power supply? I don't have enough money to get that and a pump. will the iwaki 20 just plug into the wall?

RD Pumps require a 24 Volt power supply
(W)MD pumps are AC powered.

If someone locates a 3/8npt to 3/8bspp or 1/4bspp thread adaptor, please post it.

Can you please update the sticky, It was last updated over a year ago..

From reading it, I decided to get the Eheim 1250

but on further research I found there have been more pumps and Eheims put on the market since the update

Which one do I get...

Of course I want to spend the least amount of money but I also want a good pump for a triple rad, dual rad, and possibly a single rad all in 1 loop

Does anything beat the Eheim 1250 in price for power?

[Bobly]

Either DDC3.2 or Laing D5, also worth considering having two in series.

Hi guys, can you help me with this ?
i started to build a wc system and in my country the only cheap pump that i can get is one called Atman but i have2 models in my mind.

Atman 103 - 1000 L/h - elevation 1.2m apox - 25w - Wide: 9,5 cm - High: 8 cm - Deep: 6 cm
Atman 104 - 1800 L/h - elevation 2m aprox - 38w - Wide: 11 cm - High: 8,5 cm - Deep: 7,5 cm

Both of them work under water and the 104 its a little bit bigger in size.

I will use only a block for my cpu and a rad for 2 120mm fan.

1.2 meters = 3.9 feet
2 meters = 6.5 feet

1000 liters = 264.1 US gallons
1800 liters = 475.5 US gallons

10 centimeters = 3.9 inch

I'm no expert, but the specs on either pump are sufficient for a reasonable setup. If you want someone to give you a more specific answer, you're going to need to post what you plan on putting in your loop.

Or just use martin's flow rate estimator (http://www.martinsliquidlab.com/Mart...Estimator.html) and pick a pump with similar specs to those.

Of course, unless someone has direct experience with those pumps, it's up in the air as to how loud or reliable they are.

Both pumps will give you a great flow on a low restriction setup. They are not suited for high pressure drop WB like the EK supreme which will kill them for sure.

Even a GTZ or a Storm should work fine. They are pumps like Eheim 1048-1056-1060 series

You could even add some low restriction NB and GPU WB like a MCW30 or MCW60 if you like

Also keep with 7/16 or 1/2 id tubing and low restriction radiators like the TFC, PA and MCR series

[Azt3c]

how can i know if any of those model work on a jet block ?

[SuporterPoli]

Can you please recommend me a good pump for a 9.120 MoRa radiator? Tubing will be 1/2 or slightly smaller.

[ZL1Killa]

is the mcp655 the badass of the DC pumps (wattage wise) and then the RD-20/30 comes in at the most badass DC pumps (heat dump high however)??

A lot of pumps have been discontinued and killed, I think we should update this thread at some point.

[Bolas]

Yes please. A thread update would be most welcome. I'm trying to pick a pump and I don't see some of the recommended models. I'm at a loss for how to evaluate some of the existing ones.
