2 Apogee XT's in a series, what pump?

[Wiggy McShades]

I'm planning out an SR-2 build and I have one XT from a current build so those are definitely the blocks ill be using. Currently what I'd like to do is have the two XT's and a MRC-420 in one loop, but I'm not sure what I should look for as far a pump goes. Right now I'm looking at a D5 with an XSPC reservoir, but is that going to be too under powered? Also is there any chance running the blocks in parallel is a better idea?



PS: anyone got any idea about when a full cover block for this board is going to be available?

If pump gonna be D5 with it's lesser head pressure then that of DDC's, yeah, imho better put both XTs in parallel, as they are relatively rather restrictive.

believe me you don't want the D5 for that restrictive loop running in series ,the DDC 3.25 with either XSPC or EK top would be the best option as you need a pump with high pressure,as for the SR-2 block EK has one being made and the ETA is 9th of july as it is stated on their website

[Wiggy McShades]

would there be a big difference between 1 and 2 ddc3.25's? I'm looking at some of the dual ddc tops and if these blocks are that restrictive is a dual ddc setup a better option? or is one good enough considering I'm only going to be using 1 MCR-420?

[Alexandr0s]

I think a single DDC3.25 should be enough for those two blocks and that radiator.

+1 IMO one DDC 3.25 with a top for 2 XTs is enough

Try and take some photos as you go, would be nice to see

+1 i wanna see as much as i can of the SR-2's builds

A second pump will get you 1, maybe 2C, not really worth it imho.

I'm planning 2 XT's on a D5 with a HWLabs GTX 560 rad and a board block by Bei Fei in Texas..
Will have the board block in hand next week.
The rest is here nowincluding a nice custom front for the MM Extended Ascention drilled to hold the GTX560..
Very sweet!

[Church]

Are you shure you want GTX (less effective with silent fans), not SR1 (made for such)? And are you shure you'll be able to mount that long rad (605mm) with ease in your case? Good 140mm fans also hard to find unlike 120mm ones.

[WhiteFireDragon]

like others have mentioned many times already, a regular mcp355 with a top can handle two blocks and a large rad fine

dave entering the world of watercooling?? we don't see this very often

I have the GTX560 and silent fans? What are they?
I have 4-65cfm 140mm fans and if needed I'll get 4 more and do a push-pull.
Yea, it will fit, had a custom front made for the case just for this rad

Nope, but it's been a couple years, it's time..

[Wiggy McShades]

Nope, but it's been a couple years, it's time..

I saw you're avatar this morning and started ordering so evga, MM, and various other companies that received my paycheck have you to thank.


BTW what are you doing for a board cooling loop/is your full cover block going to be in a loop of its own or with something else? and hows the bclk ceiling on the board? I'm having a tough time picking cpu's

Hey Seeka Your sig reminds me how ignorant us americans are.

*sigh*...

Sad thing is 5/10 people u ask, i bet you would get the same answer.

[Alexandr0s]

Naekuh, you have anything particular to blame for that? I've always wondered 2 things:
1. is the stereotypical ignorant american a realistic image of actual americans? I've found out on several occasions, it is.
2. Where does this ignorance come from? I mean, I really doubt the educational system is that different. Is it the tv, should we blame the parents? perhaps even Canada (for those Canadians that don't realise it, that was a South Park reference. Covering my ass, just in case ).

Most americans seem to not get out much further than a their own city, so that seems to help add it it.

Also there is still an elitist mentality that America is better than any other country.

[seeka12]

what really gets on my nerve is while watching American movies and TV Series that arab people only appear as terrorists ,what really eases it on me that Terrorists only appear for few seconds in the American movies and Series

[Genesis:.]

hey! what was that about Canada!? *waits for an answer while shuddering in igloo*

As correctly stated in several response, it would be beneficial from a performance standpoint to parallelize your XT's. Since we have two identical waterblocks, the same principles discussed here also apply to this configuration. As to the choice of pump(s) this remains a matter of preference, as the performance impact remains nominal; if space allows it, and if you parallelize your blocks, the MCP655 is theoratically a slightly better match. But if you do not parallelize, then the 350 or 355 series are theoratically better.

Yo i buyed 2 apogee xt 1 week ago for my evga sr2 and i tell you its not enought power!!!! i was rly piss off that i have to much temp with that 2 blocks thermochill 120.4 and laing d5 pump i wanna ask what i can do i have 2 loop already 1 for sli and second for that cpus dont wanna do another loop you sure that DDC 3.25 have enought power for that 2 apogee xt with rad 120.4??

[Church]

You can paralelise without spliting completely separate loop just fine. Simplier for SLI/CF gpu blocks, a bit more work for other water blocks (like cpu wbs here), but no rocket science needed anyway. Eg. with Y-adapters like these before and after ..
Such parallelising will greatily reduce overall loop restriction, that would help with pump like D5 with it's lesser head pressure. I'm guessing that DDC-3.25 might handle two of XTs in serial just fine though (i don't take into account rad restriction, as it's relatively is very small and almost irrevelant).

I lose any performance doing something like this?

Based on my personal usage, I would do this:
1/ serialize the two loops into one
2/ parallelize the SLI blocks and the CPU blocks
3/ connect the parallelized CPU blocks to the parallelized GPU blocks in series.

Now ask yourself this question: what do you intend to do with this new machine? Are you going to be crunching numbers 24x7 on all 16 threads (or 24 depending what CPU you use) in the background while at the same time playing COD or Crysis ?

Conversely, if your usage model is more or less like the majority of people, you are probably using this high-end system for specific CPU intensive tasks typically in a professional or specific pro/hobby environment, and play games at other times when you are not working. In that case, you will be putting max load either on the CPU OR on the GPU's, but seldom if ever on both at the same time. That's exactly where you will benefit from recombining your loops, because you will have two radiators to dissipate the heat of either your CPU's or your GPU's rather than one.
