Typhoon III & D5 -or- XSPC dual DDC pump res?

Been following the T3 thread, but was wondering how the T3 and a D5 pump might compare to the XSPC dual DDC pump reservoir? Both of these pump/res units allow for 2 loops, but would the dual DDCs give you higher pressure or more flow in a 2 loop setup?

I have the option to use either, but let me explain how my 2 loop setup would be. Loop1 would have a 1080 rad that would be used strictly for an OC'd i7 920 D0 CPU. And loop2 with a RX360 rad that would be used for dual GTX295 blocks and NB and VReg blocks.

Both the T3 and XSPC setups use a single res for the dual loops, but would one give better performance over the other for the above setup?

This is the XSPC res I'm referring to:

I don't think enough data has been collected to determine whether the T3 would be better or not. We need someone to chart efficiency numbers of the T3 running parallel loops at different pressure drop values before we could say which is better.

I do believe we have enough data to say, though, that the T3 will win in a low-pressure-drop pair of loops, and the dual-DDC res would win in a high-pressure-drop pair of loops. The question is; what point does one become better than the other ?

I *think* my setup would be low pressure drop loops, so perhaps the XSPC res may be the better option of the two for me.

EDIT: Oops - I meant to say I think mine is a high-pressure drop setup. :yawn:

Yea, it did seem there was talk of it not responding well to really restrictive loops. It seems Skinnee is going to have data out here any day now, so I may try to wait on that data before making a decision.

Which, the XSPC res or the T3?

The T3. I should check and be certain though, I read that whole thread like an hour ago, so I might have confused it with something else.

Alright, here we go:

Let's take a sample loop of the Aqua Computers Double Impact, two MCW-60s, and two HWLabs GTX480s. Two of the most restrictive rads, a very restrictive CPU block, and two standard GPU blocks. Not only that, but I'm quite sure the ACDI is one of the more pump-hungry blocks out there (that doesn't mean most restrictive, that means an increase in flowrate does the most for its performance!).

In a normal serial config, this setup will get .89GPM. With the Typhoon III, splitting the ACDI into its own subloop, Subloop A, and everything else into Subloop B, you get 1.34GPM through A and .98GPM through B!

To put that in perspective, two D5s in serial (with the rest of the setup in serial) only gets 1.30GPM!


Another possible config: Apogee GTZ, 2xMCR320, and a single MCW-60 (yes, an all-Swiftech config). All in serial: 1.39GPM. Split up with just the GTZ in Subloop A: 1.79GPM-A and 1.66GPM-B.

Adding another MCW-60 to Subloop B drops serial flow to 1.30GPM, raises Subloop A to 1.85GPM and lowers (without any drop in performance) Subloop B to 1.49GPM. Again, the GTZ is a block that LOVES flow, so the Typhoon III is helping performance quite a bit here :)

Not only is the CPU block getting a significant boost in flow with these configs, but the secondary components are also getting a slight increase. :D

No problem! :) So what do you think with my loop setup - the T3 or XSPC res? Or at this point we really don't know what the better option might be? :shrug:

I would wait for Skinnee's results. I am leaning more toward that T3 from reading that thread, but I think it worth waiting for the data :up:

edit: you can always put those DDC's and that dual top on the for sale section and get some money back out of them ;)

Well, with my current single loop configuration, I know that my D5 (PMP-450) gave me 2.5 LPM. Moving to dual DDCs with the Watercool top is now giving me ~3.5-3.8 LPM in that same configuration. I can only *assume* that my dual DDC setup would give me better flow in a dual loop setup over the D5. But then I never tested the T3 in my single loop, so I can't compare directly to the dual DDC/Watercool setup.

Very true! :)

Umm... 2.5 LPH pr 3.8 LPH you need a new pump! I assume you mean GPM.

Crap, sorry my bad :yawn: - I meant LPM. I corrected my post above.

What is really awesome is that we have a choice now where we didn't a few months ago.

Agreed. The fact that we are finally getting some decent options from a variety of manufacturers and that their is some sense of standardization shows how matured the water cooling scene has become.

:up:

I ordered the XSPC dual DDC bay res and some other parts last week from Performance-PCs. The parts arrived Friday, but instead of sending me the XSPC dual DDC bay res, they sent me a standard XSPC dual bay res (for no DDCs). Arrgh! :mad:

Now my build's on hold and my PC has already been drained, taken apart and just sitting there with nothing I can do until I get the correct part. I've emailed P-PCs, and hope they take care of this issue in an expidited manner.

Good luck on that one, with PPCs

Thanks. They emailed me back today indicating they're sending out the correct part today, with a return shipping label included.

I hate to bump an old post, but I'm curious of the same thing. For a similiar multiblock setup described by the OP, which is the better option, a D5 vario and T3 or the dual DDCs and XSPC pump res? Looking for expected flow rates with various levels of restriction and noise? (I've never run a D5)

Well, we haven't got a review out of the new XSPC dual loop version, but IMHO both are fine for multi block loops.

The biggest difference is if you want to get 2 pumps, or one. If you already have a D5, then get the T3, if you already have a DDC (guessing you do. :confused:) I would just order another DDC and the XSPC.
