Choosing The Best Pump for Your WaterCooling System

well i will tell
im runnin a mcp 650 and it rocks, it moves 315 gallons an hour
i went from a constant 45c - 48c
now with the pump outside the case and case wide open
my p4 3.4 800fsb 512 cache is idling @ 25c to 27c
i think b 4 i added 6 fans around the open case
it would idle at 28c i couldnt believe it

so b 4 i added pump i could only get up to 221fsb x 17 multiplyer
which would put the cpu @ around 3.75ghz somethin lik that
now im runnin round 231fsb x 17 or 3.92ghz
it varies cuz this thing also auto moves
i have come outta a game n have seen it as high as 4.15ghz

i have a water block here monday 1-31-05 for the intel mb chip

we see if that improves systems temp, its @ 23c - 25c

i have a swiftech 650 and it rocks dude
check out my message reply to this issue

ancient, I just checked out that review. Thankfully the author made the sencond test setup. I had asked him to make a more current one as i really love his reviews, just that the test rig was outdated..

the ddc seems to be the pump to beat when modified. They would be very comparable to a MD20Z when modified and in series.. I just wish that they were 1/2inch on the outlet too.. that would make it alot better.. I wonder if there is a way to mod it there too.

You wouldnt really see any performance increase by putting a 1/2 outlet other than making it compatible with 1/2" systems. Its pretty easy to just slip a small piece of 3/8 x 1/2 tubing over the outlet before you install the 1/2" over the top of it and clamp as normal.

What about the Hydor Seltz L35? Does this pump generate much heat?

I can heartly recommend MCP600 as well. On my waterloop, it can keep water temp only @ 2c above ambient priming 2.94ghz 1.73-1.76v on FX-55. (MCW-6002 A64, Weapon heatercore in 1/2" ID loop) That is with fan running @ 7v :) Wish I had way to measure CPU temp but I am happy.
MCP350 seems to do good job as well which is on my video card loop with silverprop Fusion HL keeping video card cool (still haven't don't volt modding with heavy overclock to quantify yet but 550/560 XT with stock volt is only 10c over ambient on video temp with MCR-80 dual radiator :))
Truely amazing is it's size. It is just a little bigger than Maze4 GPU block!!!!
I can heartly recommend either one to anyone jumping into H2O depending on your preference. (space constraint is not the big problem anymore with either of these)

Anyone know?

I would guess in the 12~15w range.

u sure its that low?

Thats its wattage right? So what does that mean?

wattage is amps times volts.. 15 watts is quite low for a pump. .the lowest i know is the mcp600 with 7 watts of disipation. My iwaki puts about 30watts into the water supposedly.

Please note that teh wattage consumption is not the same as the wattage going into the water.. not all of the heat is put into the water.

So is 12-15W good, so-so, or not good enough for overclocking?

12-15 watts is good.. its very low wattage.. which is good.

It isnt really good as far as to how much it adds for the performance. That puts it about the same as a D4 and close to double the MCP600/AQX50Z both of which will out perform it, and more than a Eheim 1250 which has about the same performance.

lol i guess my perspective is a bit off... lol.. im so used to my iwaki..

Which of these will provide the best performance in a very small loop just for video card. It will go with a HeaterCore, MCW50-T, and Tygon 1/2" ID tubing.
The MCP600, MCP650, Laing D4, or an Eheim 1250?

mcp600 as the heat dump will be the least and it has high flow. btw mcp650 and D4 are the same pump.

Well.. 8 pages later and screw the quotes...

Nobody addressed the question of Little Giants, so I'll sum it up:

The original Rainbow Lifeguard Quiet One is NOT even close to the same thing as the new Pentair Aquatics Lifeguard Quiet One. The originals have great specs and are goddamn silent. They used to be inexpensive. I just lost another bidding war on ebay and the RAINBOW lifeguard quiet one went for almost $100 shipped. :( I have a few friends at other forums who are absolutely in love with their original Quiet Ones.

Since I can't get my hands on one, for now I'll be using a couple Via Aqua 1800s in series. I don't believe these are the crappy pumps every Iwaki owner will insist they are (Iwakis are great pumps, not only do they pump water but are also great at pumping cash from your wallet) :D The Via Aquas are meant to be submerged for cooling. Even if you run them inline. Yet many people don't, and they still last for quite a while. Based on this I decided to be the cheap bastard that I am, and run a couple in series for a whopping total of $50, and if one fails, not a big deal. I'm also going to run them submerged in their own baths. If this thread is still kicking when my rig blows up I'll come on back and eat my words. :rolleyes:

-Luf

sounds good man.

well i was about to get ready to add another pump to my listing but when youy said hte new one suck (is that what you said in not so many words?) I wont bother.

MaxxxRacer, which of the Iwaki's will give good performance while managing to fit in the case?

what will be better for a weapon heatcore and shroud, 1/2'' tygon, tdk block, swiftech res.

50z, mcp650, or should i go for a iwaki or blueline. i pefer the smaller 12v dc pumps though. if i use the 50z or 650 will i have bad performance because its a smaller pump or can they hold thier own.

it iwll be 5/8od 1/2id system

I recently ebayed an original Rainbow Lifeguard Quite One pump & I must say it is very impressive (1140gph at 0 feet). Weapon hooked it up in his kitchen sink & the flow is like a friggen' garden hose---could even hold my thumb over the end & do the high pressure spray thingy. I replaced a Lifetech pump in my 2 room watercooling system & my cpu temp (according to socket sensor---8rda+) dropped 2C. This is w/ a rather poor choice for blocks to use w/ this pump as well (Maze 2-2). I plan on upgrading soon to a Swifty 6002 & prolly add a 2nd WeaponCore (since I get the friend's and family discount, ;) ).

To be fair to the L30. I would like to say that I've used one for a little over a year and had no problems. Also I'm using it with the Black I ce Extreme Pro II. The cooling isn't bad 45c is what it runs at under load now it was up to 50c when I just had fans pushing on the rad. Now I have a L35 its also a good pump so far, but Id say it creates more heat.To give you an idea I put it in a open loop with no rad and after a few hours the water was about 85-90 farenheight. I am trying to lower temps right now so I'm going to reconfigure my cooling system. Going to try rad before and after pump among other things. After I reach optimal performance for these components I'll report back. Then I might try one of the other pumps discussed in this forum. I bought mine when I didn't know jack. Peace

jnr, stick with the 50Z. the iwakis are great, but if your looking for something that will fit nicely in your case and be easy to work with the iwaki is not that... lol.. its an amazing piece of gear but it makes working on ur comp alot more dificult.

Does anybody know of the consequences of hooking up two pumps(L30 and L35) in series, with different flow rates? Good or Bad?
