In need of some opinion(s)..

[fragmaster]

Hey guys.
I need some opinion(s) on a wc rig I saw today at this pc store here in NY that I really liked and I'm thinking of having something similar if u guys think it's ok.
The wc set up is housed in a custom made wooden box,similar in size to a shoe box but a little bigger. On each wall. They have a DD double heatercore with shroud hooked up in parallel with 4 sunon fans sucking air in (2 on each hc), a DD Dual 5 1/4 bay reservoir, an Eheim 1260 ( 600 gph wow ) hooked up to a critiCool powerPlant , TDX Block cooling a 3.4EE, tygon tubing going out from two holes in the box to the tower. They are using a mixture of zerex,DW and some uv dye and the whole wc loop was 1/2".
Now my questions lol, I don't know why they're only cooling the 3.4EE with this set up?? could not ask since everyone was busy with whatever they were doing but I'm sure that pump and those 2 hc can handle any chipset and gpu blocks???
I really liked it, very quiet!! plus I like the idea of the wooden (shiny oak) box
what do u guys think my temps would be if I would go with a set up like this one.
Would it handle the heat southern Florida has to offer lol.
Any comments?? what would u do differently?

It'll handle the heat, but an actual temp is really hard to predict. It's going to depend a lot on the actual airflow.

Txs BB for the reply..
I know this set up will be able to handle the heat with those 2 double HC and that 600 GPH pump but don't u guys think that this pump is overkill?? what are the benefits of having this pump instead of let's say the DD or the eheim 1250?
do u think the 1250 or the DD won't be enough to push water through those 2 double HC considering only the TDX and reservoir in the loop? If not, then 1260 600gph is the one I'll be getting and I'll add a gpu and chipset block to that.
now with those double HC, is it better to have them in parallel or in series?
I already made up my mind about how to set it up, I have plenty of room in my Lian Li V2000 but I really liked what I saw at that store, so an external box it is, I'll have something made up of aluminium to match my case.
Give me some help guys please before I pick the phone up & call those nice people at DD .
Thank you

I would stay away from the 1260 if I were you, as it's not a great choice for watercooling. Its PQ curve is very flat (due to a high maximum flow rate and a comparitively low shut off head), and as a result you'll most certainly be operating the pump below its peak efficiency. pHaestus has done a great job of summarizing a variety of pumps here, which you can use to help make your decision (and if you can't, feel free to ask someone here how to do so).

[fragmaster]

Skulemate, I took a look at pHaestus's article and the 1260 was not mentioned there. do you have any link(s) where I could dig some info?
The wc set up I saw in the store had this pump running, it was quite, not as the 1250 per say, but it was doing a very good job cooloing that TDX block with those 2 double HC.
ok then, so let's say I use the 1250 I have now on my pc + 2 double HC ( parallel or in series ????) + tdx block + chipset block + gpu block + reservoir in a 1/2" loop,
would that be better? I still do not know if I should go with 2 double HC or just one? Oh, well I'm more confused than before now
keep it coming guys.
Thx

Yes, I realise that it is not plotted with the rest of the pumps, and for good reason. If it were, it's head capacity would fall just under that of the MCP600, and its maximum flow rate would run off of the plot. Keep in mind that this pump consumes 50W, compared to the 28W of the 1250 (which is still not a particularly great choice for watercooling incidentally), and that you will be running the pump in the flattest region of its performance curve (meaning that a small change in system restriction will have a large impact on the flowrate). While you may well achieve a slightly better flow rate with the 1260, I don't personally believe that the extra size or power consumption of this pump is worth the gain.

The 1060 (not 1260) is actually a very large pump, but its main advantage is that it has a 10 ft head (max pressure), putting it more inline with the other premium pumps that are now available. Otherwise, Eheim has a good reputation for durability. (see eheim.com for more info). The 1250 has a max head that's a bit low (IMO) to run a loop with two cores. You might want to check out what other people here use for a pump. Pressure is everything. The DD pump has a 10 ft head already.

Cores ought to be in series, usually. As Bill tested, they work best with an actual flow around 1 to 1.5 gpm, so knowing your actual flow rate can come in handy here.

[Skulemate]

Ben, I was under the impression that the 1060 and the 1260 are the same pump.

[bigben2k]

Last I checked, there is no such thing as a 1260 (it's a misnomer: it's really called the 1060).

[Skulemate]

Well then, I rest my case.
