Choosing The Best Pump for Your WaterCooling System

[Brandon_Tyler]

I dunno, I'm now leary of using my WMD-30rlzt, According to some it uses in excess of 90 watts which atleast 50% gets dumped into the loop. So, I wouldnt think that the LG would be more efficient at dumping heat. Therefore I wouldnt think it'd be wise.

-Brandon

PS What do you not like about your Hydor's in series? Ive got 2 L30's Ive thought about bridging in series.

[yasoumalaka]

well when I tested them on my counter top I got around 1.77GPM with my blocks rad and res all hooked up, but I'd like to get more flow so I'm searching for the perfect pump? I found the little giant pump because i was just searching around google to discover a pump nobody has used yet. People have used Little Giants but I'm not sure about the one in my previos post. I'll be finding and posting other pumps that I haven't yet been used in watercooling so that we may discover the perfect pump. If it hasn't already been found.

[yasoumalaka]

I would think based on the proposed application of that LG model and on the other statements I have posted from theLG website that there is less than 50% dump on that pump.

[Brandon_Tyler]

This is the pump I hope to be buying soon. Blue Line 20 HD I'm jsut not ready to commit to one pump yet though.

-B!

[yasoumalaka]

Brandon_Tyler I'm no expert on this subject but that pump seems like it would work well.

[Brandon_Tyler]

Oh I know it'lll work well. I just need to rehash the design of my external enclosure to make damned sure thats what I want.

-B!

[MaxxxRacer]

the blueline 20hd is exactly the same as a iwaki Md20.. like exactly. its even designed by the former head designer of iwaki. its the reason that the pump looks almost exactly the same.

[Brandon_Tyler]

Max, do agree with me that my WMD 30RLZT is going to heat up to much to be effective in a dual core system, unless it were two of Wepon's Monster cores?

[yasoumalaka]

MaxxxRacer please comment on the Little Giant I posted previously. I know you know a lot about pumps. What do you think the heat dump will be like based on their statements in my post.

[EnJoY]

That pumps specs are similar to the Iwaki MD20. However, it has a higher wattage (heatdump) but higher flow. Overall I'd say it's not worth it.

[yasoumalaka]

EnJoY what do you think this statement means? Do you think it is just marketing poo or that the pump really dumps most of its heat into the air? Or is this just the code for normal pump stuff?(Thermally protected open fan-cooled motor with sleeve bearings. Also the Magnet housing acts as an insulator to prevent motor heat from being transferred to the fluid being.) The only reason this cought my eye is that the pump produces 300GPH at 9ft head. I wonder if my blocks could even handle the pressure. I would have to leak test for a week or something. (Watercooling joke. get ready its hilarious) I've been looking for pumps nobody has used yet and I've come across alot of pumps that can actually pump 300GPM of terd. I think intel may be using these pumps to cool their marketing department. Its been running hot lately. I have no clue why I thought of this. Peace!

[MaxxxRacer]

enjoy the wattage is 45.. same as the md20...

yasou, that pump is very similar to the MD20 and the blueline that was just mentioned. the 3 of them are nearly the same thing. they are all rip offs of the MD20

but that little giants heat dump is gonna be way wya wya too high to make it worth using. the MD20 would be a much better option.

Brandon, the MD30 is not worth using unless you have a very large rad like the monster core. not sure if you would see gains over the 20 with a 302, but you would see gains with a monster core.

yaou: the pumps based off the iwaki designs have a relatively low heat dump as the impeller is seperated from the motor housing. this is why they only dump about half of their heat into hte water unlike pumps like hte DDC and 50Z which dump about 95% of their heat into the water.

9ft of head is equivalent

[yasoumalaka]

MaxxxRacer would you say that the statements I posted were describing normal pump features or something different in the design of the pump but pretty much useless because the heat dump is still very high. Something that I've noticed is that pumps with high flow consume alot more power, even if they have low head. I'd like to find a pump with high head and flow but is aircooled. I thought that is what I found. I guess I'll search further. It could pay off in case I need to find a terd pump or something. I'm going crazy

Honestly there are pumps made for pumping terds. Could you imagine studying terd dynamics. I bet you could learn a lot of usefull crap in that class.

[yasoumalaka]

what do you mean by (9ft of head is equivalent). On the spec sheet I think it said something like 3%$GPH@9ft

Thank-god the DDC only consumes about 8 watts!

yasou just get an iwaki.. it will make ur life easier...

lol. Agreed.

Wich pump shall i take.

Alphacool AGB-Eheim 1000 Station = 55euro

Or

Eheim Universalpump 1048 220 Volt + reservoir = 73euro

[MaxxxRacer]

most certainly the 1048, although both of those pumps are way underpwoered.

and btw dont get one of those aluminum resivours. get a normal acrylic one. the aluminum ones will cuase corrosion and are just dumb.

Could you explain (why the 1048) whats better

If i take the 1048 i will buy this reservoir Cape Coolplex 25 external

although both of those pumps are way underpwoered.

Well thats the european way, we don,t like to much power

Normaly we use a 600 L/h pump, 1000 l/h is considered verry heavy here.

[MaxxxRacer]

the maximum flow rate doesnt mean a whole lot. especially for the EU blocks and tubing. head pressure is the biggest thing. EU gear is so restrictive you need a very high pressure system to overcome this.. even an iwaki md20rz is gonna get choked up.. scary though if u ask me.

the 1048 is better in this case as it is not dumping all of its heat into the water like the other pump. both of the pumps are underpowered so that isnt much of a consideration at this point. its all about the heat dump. when your pump is submerged in the water it puts all of its heat into teh water.. but the 1048 wont do this. it will dump a little over half of its heat into the water (this is an estimate of course as eheim isnt about to release heat dump numbers as there is no reason to).

if you get that res make SURE you use anti corrosion as it has aluminum endcaps. one thing ive noticed with most of the parts on that site you linked me to is that everythign uses aluminum which is a big no no if you are using any copper in teh system which you will undoubtedly do.

btw take a quick read to my introduction to watercooling guide if you havnt already. it will explain some if of the points im talking about here in more depth..

[RaptorRaider]

Do you have any idea which Iwaki MD-20 performs best? RLT, RLXT, RZ, RZT or RLZT?
My guess is that the RLT and RLXT perform less than the Z's but which of those are best?



Edit:

If anyone has ANYTHING they want to add please do not hesitate to pm me. If you think that any part of my post is biased or just incorrect, please let me know and I can change it to be more fair to all products.

Here we go...

Surprisingly enough, when this pump is run at 13.8 volts it will beat pretty much any pump on the market. It is only beaten by running two of them in series. It is quite amazing only drawing 8 watts of power. this really is the ultimate water cooling pump. Low power, high head, and great temps. Its only downside is that it is not as long lasting as some of the others. I have no real data on how long it will run for, but suffice to say that the iwaki will outilve it by a while.

Don't forget to tell that this pump is the Swiftech MCP600/AquaXtreme 50Z; looking at what you posted above it make it seem that you're talking about the Swiftech MCP350/Laing DDC.

then head on over to the link I provided.

Don't forget the link.

1.It has more head pressure 2. Its cheaper.
It sucks about 7 watts of power

That should be 8W, right?
It also dumps less heat and makes less noise.

[MaxxxRacer]

the RZT performs best with restrictive systems.
the RLT is best for really unrestrictive systems

all the others should not be botherwed with

did i not put the link in there??


"It dumps less heat and makes less noise."

you refering to the 50Z and D4 comparison?

[RaptorRaider]

Not the answer I was hoping to get; thanks anyway. I think it's rather stupid that even Iwaki doesn't give us any information about the difference between their pumps.

did I not put the link there??

I'm an idiot.

"It dumps less heat and makes less noise."

you refering to the 50Z and D4 comparison?

Yeah.
BTW, according to this review, the D4 has more head than the MCP600/50Z.
