If this has been asked before I'm sorry I just didn't have any luck trying to find the information while searching. Everyone asks for pump recomendations but I want to find out what is needed in a pump. Obviously low noise is nice but how much GPH is actually needed.

I want to cool my CPU, GPU, and NB. Everything is going to have a 1/2" tube.
I'm getting:
Black Ice XTREME-2 Radiator
the Innovatek Tank-o-matic with the barbs switched to 1/2"
Dangerden TDX block
Dangerden Maze4 GPU block
Dangerden Maze4 Chipset Block

And I'm not sure about the pump yet.
The pumps I have available at the place I'm ordering from have different GPH ratings.
There's the MCP600 V2.0 that does 160GPH
There's teh MCP650 taht does 330GPH
There is also the CSP 750 and a Dual CSP750.

For what I want I would like to know what would be required to run it. How much does the GPH really matter? Am I lookinig/comparing the wrong properties when it comes to pumps?

I'd appreciate any information you can offer.

Don't bother with the NB chipset cooling and go with an Eheim 1250. Although, the 1250 can handle the NB as well... but it's pretty pointless to do the NB.
 
James, have you considered the Delphi pump sold under different brands? This seems to be one of the best pumps around now. Swiftech sells them as the MCP350 while Danger Den sells tham as the DDC-12V.

That pump only does 105GPH if google conversion is correct. Is that enough for what's in my loop?

I'm just curious because a lot of people recomend the MCP 650 which pushes about 330 GPH. I've heard it's a little loud but what's the benefit of the exra GPH?
 
Personally I would only consider two pumps if I were buying right now, the Laing DDC/MCP360 or the MCP600/AQX 50Z. I believe the MCP600/AQX 50Z would perform the best but the DDC should be withing 1°c and it is smaller, quieter and has a 50K hr MTBF which the MCP600/AQX 50Z does not have.
 
Many on these board would disagree with me, but I really like the CSP 750

I run two of them, and they have both been great. They are plenty powerful, but the best thing is how incredibly small they are - about 2" x 2" x 2"

I con't wait until the third revision comes out.
 
The two important specs to pay attention to are head + flowrate.

Head is the ability of the pump to apply pressure, flowrate is the amount of water the pump is able to push through with no tubing. Aquariums tend to prefer high flowrate, low head pumps, while watercooling tends to prefer high head, low flowrate.

Cathar did a pump comparison on Procooling.com that put the MCP600 at the top of the heap in most aplications.

Id recommend staying away from the CSP-750 as, even after the Mark II revision last Nov., they are still suffering from the same seal leakage problems. Most people wont have problems with them, but if you do itll die and C-Systems is now notorious for terrible customer support.
 
I just bought a via aqua 2600. it leaks but i did the sound mod on it and then sealed it with plumbers goop hasn't leaked a drop since then. It is a big pump but my temps dropped about 6C at load after upgrading from a 1300
 
^^^ What Mike says :D

MCP600 is nice but me thinks DDC is cool and quiet, and MCP650 is teh king of the hill if u interested in GPH and dont mind a lil' noise ;)
 
I've got teh DDC and it's quiet as hell, not to mention its size. From what I've read its best suited for high-pressure applications... so take that how you will.
 
Well, considering my system runs at 2* over ambient idle, 8-10* over ambient load w/ slight overclock (2.25ghz, 215 fsb).... I'd say sure.
