I've had a look at various pumps available.

You seem to be able to get them from about 10pounds to almost 100pounds.

What specs should I be looking at to compare them?

Are there any well known quality brands I should look out for?

Are there any well known really bad brands I should steer clear of?

I see pumps come in a variety of connection methods, from a simple 3pin fan socket to Molex and even USB sockets. Do the USB versions interect with windows some way?

I'm looking for something quality and well priced.
 
Hahaha, I'm so confused.

How does that thing work? It only has 1 connection? I was expecting like a water in then a water out like 2 connections for tubing.

Thanks for being patient with me dude.

okay, I'm going to link to amazon because they have an example of what I was expecting. very sorry if that's against the rules, just tell me and I'll kill it.

*Don't link to competitors!* Sorry, sorry. won't do it again, I promise.

Also, I'm going out now. will reply to anything further later :)
Thanks again.

The d5 needs a pump top (which has the input and output threads) or a reservoir top, which again has the input/output on it.

Maybe it might be best for you to look at the pre done d5 pump/rez combos as then it will be all done for you by overclockers, and it's less confusing for you, alternatively, have a look on YouTube for d5 pump assembly instructions, im sure they will have something and it will clear up the confusion!

Hope this helps a bit more!
 
I was thinking what would be the indications of having a pump not sufficient for the loop? coz I am having a similar situation. I used the EK 4.0 for 6 months now, dunno if I change it to D5 will benefit a bit.. = )
 
Hard to judge, really - it's not something which would have obvious 'symptoms' unless it was particularly bad, other than the pump killing itself. But that's really not a good way to judge.

I suppose if temps were raising steadily throughout operation, and didn't level out, then you'd be able to establish a weak pump - but that would require you to have tested the exact same loop with a stronger pump in order to confirm that it wasn't fans, or rad space, or some other factor.

You've got quite a restrictive loop though, so it does sound like a D5 would be a good idea.

Hmm so you say you think you're having problems with flow rate? Interesting to me as your setup is exacly what I was planning to have, still wondering about the extra 120mm rad.

Why do you think your problem is flow rate? What exactly is your problem? temps not as low as you were expecting?
 
Hi, cooling a i7 920:4.2ghz + 6970:950/1350mhz with a 560 rad low rpm fans + Phobya DC12-260 600LPH 12V Compact Pump can't complain at all about my temps even with the hot spells.

Interesting. I see that pump has a much more manageable price tag.


I would only be using a total of 480mm of radiator split between 2.

plus I'd have 2 GPUs. don't know if this would mean I'd need a better pump.:confused:
 
Hmm okay. I'll concede defeat, everyone seems to love that D5 thing. I'll make that my pump, now to move onto all the other bits, going to be a hell of a long process.

Thanks for all your help everyone, I'll get a D5 whenever I make my order.

With the D5, you'll need a pump top and a res if you don't have one.

That's a good bundle to go with as it contains the pump, a top and an attached res.
 
I'm keen on a 5.25" mounted reservoir so I'll probably go for the standard pump top, haven't looked at all the options yet, dont know if they make a D5pump-res combo in the 5.25" bay
