Very nice block,

the block uses cathars pitted design from his storm.

i wouldnt be suprised.

Andy, please tell me your doing a proper posted review of this block? It would be nice to actually see how it performs compared to the V2, GTZ and Supreme and not find some kind of egregious error in the results....then maybe I can shut up and this topic can die. :up::ROTF:

Should have some prelim stuff by the end of the weekend,

Take your time Andy, and PM me the final results. :up:
Are you planning on testing all the nozzles?

temperature difference (Core CPU - H2O)
at different flow rate? ......... three or four ? ;)

Accommodation and inclusion of nozzles I think :p:

i.e., Rev. A comes with nozzles and works with nozzles while the original can't even fit/take the nozzles.

Looking forward to your results :D

My CF/Dallas probes should be here fairly shortly too :lol:

I think he wants data in a few varieties, or is wondering if you're going to do it.

1) CPU temps minus water-in temps.

2) #1 as it changes with a decrease/increase in flowrates.

One things for sure though, it's working pretty good just the way it is.:up: Once I see how well this one measures up against a Supreme, I might just buy the latest version.

Not sure myself. All the images I've seen of both rev's show them both to be very similar internally. It'd be nice if Enzo-Tech(Dav) could magically re-appear and explain the differences. :yepp:

that is the formula used by Excel :D
The same formula used by Martin........for the radiators
Delta temp. vs RPM (Air rate)

"...........The first curve, to me , describe correctly the physical phenomenon.........
follows the points and approaching asymptotically the X axis.
Is very precise for flow rate 100/800 lph........... and also > 800 lph.
Likely for flow rate < 50? lph is less accurate (wrong).

See above

A trendline with so few datapoints (and tightly packed datapoints in the grand scheme of things) really shouldn't be used for so much extrapolation. What's worse is that the endpoints of the actual data have the largest error compared to the trendline--does not bode well for the accuracy of the extrapolation.

I've played a lot with c/w vs. fan RPM for aircoolers and power trendlines do not extrapolate well at all. They look the nicest and are certainly the lesser of 6 evils, but the power trendlines do not play well with cooling functions when it comes to extrapolation (long story short--they lack accurate vertical asymptotic behavior as flow approaches 0 and also don't give due justice to the diminishing returns behavior of flow in waterblocks).

The interpolative strength of a trendline is viable and great for estimators, but I'd really really be careful with so much extrapolation :-/ You're doing a lot of extrapolation using a trendline that doesn't even really match the few datapoints you have, especially not at the extremes of the data :-/

blah andy i just want to know what performs better and at what flow cost.

thanks please! :up:

Do you have those plots also?

I hate to say this, but what is the purpose of this chart?
It just shows that 2 setups with identical computer and cooling components equal the same results. :shrug:

If D-Tek not soon releases their 1366 mounts for the Fuzion V1 I think I will be going with this one for my 1366 Core i7 setup. :)

The block looks great, but hows the performance? Saw Malik had some numbers, where the Luna performed better comparing to the GTZ. :)

my next build is on the I7 chip and WCing it, so You have yet another set of eyes on ya, tis okay no pressure :D I like the way it looks and yes that goes for the funky little binky light on it. :) So yes seeing some Stats on this puppy will nice.

Anyone who knows if the BP 7/16" ID 5/8" OD will fit the Enzotech Luna without those 45 degree fittings from BP? :)

I just received my 2 samples ( with one brand new block, can't tell the name for NDA) from Enzotech will test them next week on the I7 platform (when my probes get here) against the EK supreme, Swiftech GTZ and co...

Again tests will be kept simple and reproduced in coretemp charts at stock, 3.6-3.8 and 4ghz clocks (like the swiftech review) but also with added in and out watertemps...

when will this new block be avaiable you know?
