SPL-XFR3 gives you maximum adjustment of your splitter or coolant manifold. Of 5 total nozzle sockets, 3 rotate independently up to 180°. Each socket location can be quickly locked and unlocked in 13 separate positions with a spring-loaded push button.

Two G 1/4" socket plugs and two base mounting screws are included. G 1/4" nozzle sockets, nickel-plated brass, anodized aluminum base (not in contact with coolant).

Inline Coolant Filter (no nozzles) - $8.99 (http://www.FUFUFUFUFUFUFUFU.com/water-cooling/product_info.php?product_id=790)

Inline coolant filter for keeping accidental debris from damaging the pump or clogging other components. It can filter particles down to 1mm (1/32") in diameter.

G 1/4" sockets are provided on both sides, with one male and one female for easy installation into the inlet of a water block, pump, or heat exchanger. Nickel-plated brass fittings, acrylic body, and stainless steel mesh filter.

Very cool, I like that manifold. Any info on how restrictive it is?

[ballz0r]

that manifold is cool.... already thinking of how I could use it :)

Perhaps coolant into the top from a powerful pump, the three side ports off to parallel loops using valves to balance the flow with a drain on the bottom

the filter is a bit pointless tho... .ive never had a problem with debris in my loop :)

[Kayin]

There's a lot of people that cycle first time through with a pentek, though...

If you use different lengths of tubing coming out of the manifold, your flows would be different for each run off of the manifold.

Path of least resistance...

thats why id include the valves in each loop.... to balance the flow. That way you could increase the flow rate to the cpu and perhaps reduce it to the chipset....

hmmm im liking this idea... I can now see three of those new FUFUFUFUFUFUFUFU flowmeters coming off each side port

True, some do... but there's a lot more to one of those Pentek filters than some wire screen. ;)

If the wire screen were made a decent diameter (hard to tell from the photo) and were easily serviceable, it may be useful to some of the guys using evaporative coolers :shrug: [trying to be nice]

Nifty splitter, though.

[zlojack]

Well...interesting, but nothing I see here that's useful for me.

[ballz0r]

the manifold would be handy for parallel radiators... I havent seen any tests to back this up, but slowing down the flow through the radiators would be a good thing for removing more heat from the coolant... better than series anyway

[Septim]

the manifold looks like it would come in handy with an RD30, and 3 fuzion v2 on a rackmount cruncher/s...

[Gazmtk]

its nice to see FUFUFUFUFUFUFUFU actually bringing out innovated ideas.... they are finally becoming what they should be ;)
and Red I see the chance for a 3x RD30's feeding a split system loop :rolleyes:

[ballz0r]

3x RD30's feeding a split system loop :rolleyes:

why stop at three

[Gazmtk]

good point, why limit the potential :)

I cringe every time I see someone talking about radiators working better at low coolant flowrates than higher flowrates...

Some testing that Bill Adams did while with Swiftech: http://www.swiftnets.com/Technical/Assessment%20of%20Radiator%20Performance.pdf

Some contracted independent testing that Bill did for Thermochill (with his own test equipment a while after leaving Swiftech): http://www.thermochill.com/PATesting/

Interestingly, though, some of the charts later in this review by Cooling-Masters (though, as I recall, Bill had something to do with this as well) seems to suggest that a higher coolant flowrate can degrade performance when very low speed fans are employed... However, I should note that this is the only test that I've come across which shows such a trend--all of the other data that I've seen refutes such a trend: http://translate.google.com/translate?u=http%3A%2F%2Fwww.cooling-masters.com%2Farticles-38-0.html&langpair=fr|en&hl=en&ie=UTF-8&oe=UTF-8&prev=%2Flanguage_tools

Thanks for the info Petra

so radiator performance increases with flow rate... I cant understand how that works.

Perhaps the cooling is more efficient at the higher water / air delta.... hmmm

hmm it could probably be better if you have higher liquid flow rate, and a little higher air volume to cool the radiator a little faster...

that manifold should be hardened against overwhelming pressure... (3xRD30s or more...)

[RedRaider]

It's a closed loop, lower flow would seem to hamper performance due to the fact it is circulating through the rads at a slow rate..:shrug:

Tests are coming on multiple radiator loops, running RD-30 vs DDC3.2..:crack:

[CrazyJoe]

My personal thoughts on this ( although I currently have no data to prove it one way or another ) is that the cooling capability of the radiator is dependant on surface area ... and the surface area is limited by the laminar flow of a slower rate as opposed to the more turbulent flow of a faster rate.

More turbulence will allow more of the water to reach the outer walls of the radiator tubes where the actual heat exchange is taking place. :up:

[Snyxxx]

Every radiator performance curve I have seen always show thermal benefits with higher flow. This is an asymptopic relationship with flow and diminishing returns by increased flow.

Based on my personal tests:

I had a highly restrictive system with a single DDC and noted the temperatures at idle and load.

Then I simply added a second DDC in series changing nothing else. The temperatures did not change very much (maybe +1°C better) at the higher flow rate since the benefit was offset by the added heat dump of the second pump.

Therefore, I was already at the point on the cooling curve where additional flow did not show much gain in temperatures.

[Kayin]

CrazyJoe hit it on the head. We're not that limited by thermal transfer rates that we have to slow it down, to the contrary, they're fast enough that we can speed it up and still get as good or better temps. It's complicated, and I can't diagram it now, but he's headed in the right direction.
