Blackeagle, sorry that it took so long to get back to you.

The block top is acrylic and it is about 0.33" thick. Yes, that's an odd thickness, but it is either flycut down, or it came that way.

Internal shots a little blurry my apologies.

Any details on this things performance and when it'll be released?

Performance is now known (to me).
I shall not say anything publicly until Dangerden makes an official product announcement. As for when that will be? Perhaps a relevant quote from www.dangerden.com:

"Stay tuned to Danger Den...This Friday there will be a new product announcement!"

CPU Killer has given permission for those who have tested to give reviews pH :D

I don't know who this CPU Killer is; I communicate with Jeremy and Dennis at Dangerden directly. I don't feel comfortable in posting performance numbers until they say "the block is released" over there. In any case the review is not written yet and in fact I still have to run about 5-6 more remounts at 1.50 GPM tonight. It could be ready tomorrow though if Dangerden's announcement is in fact the TDX :)

Its official - the STD(X) Lives! :P www.dangerden.com
Appears that both copper and silver versions will be avaliable for XP, P4, Xeon, and AMD64 processors at the same price as the RBX, although no pricing on the site for the Silver blocks. So, the speculation ends... lets see performance numbers!

An admission I must make: the block top may not be acrylic. I never could tell the difference between that and polycarb. So, whichever one that the Lucite(tm)(c)(r) brand is, that's what the top is. :)

Anyone know of any other TDX reviews? One with the other Nozzles would be interesting.

Hmm... Same price, a little less performance, a little less hassle, and a little easier to mount. It's disappointing at best.

no alpaca the "less performance" isn't true due to lowered resistance. Should be ~same perf in actual loop due to increased flow rates.

But if you have a powerful pump like the MCP600 you still only get a low flow rate but high pressure don't you? I thought the MCP600 was only about 1.8GPH, so would be worse than the RBX wouldn't it?

Hi,

I've been following this thread closely since I was going to buy a DD TDX
and I am after honest advise about wich block to get

My set up is DD maze4 chipset, DD clear res, Hydor L30, Innovatek 120mm rad with Thermaltake 120mm fan and all with 1/2" clearflex 60

My choices are

DD RBX
DD TDX
D-Tec LRWW

Which should I get and why?
Many thanks

Is the Innovatek 120mm radiator the one with all the passes (lots of U's on either side for water to flow through)? If so then that thing has to be a flow rate killer and all the blocks that you listed make good use of higher flow rates. I'd get an $18 heatercore from autozone FIRST and then either the TDX or WW. If that radiator is really important to you then I'd go with none of the above and get a MCW5002 or MCW6000 instead (superior low flow performance). More than one way to skin a cat :) Oh and if the radiator isnt the one I am thinking of and is more like a heatercore in design then I guess get either TDX or WW and disregard above. Man I am rambling I should sleep :)

Hi,
The rad is as shown

I think it's of the second type you mention (better) with 1/2" barbs fitted

So between WW and TDX which will give lower temps?
A gut reaction?

Thx

WW will give better temperatures. Are you sure on that pHaestus? I would do the calculations to see what the exact flow would be, and thus the performance, but I've got stuff to do. Impingement seems to do better with higher velocities caused by a tighter restriction.

Edit: I could be wrong, but to get approximately equal performance to the RBX at 1GPM, one would need to have a little bit more than 1.25GPM. The TDX has a pressure drop of 14.1", while the RBX has a pressure drop of 16.3" 1.25^2*14.1" equals 22" drop, for equal performance with the 16.3" drop RBX. However, as you point out, the ease of use and mounting are much improved with the TDX, making the TDX better than the RBX. I don't agree with saying that the WW is worse than the TDX due to the extra outlet, as the WW is 3 bucks less and ~1.5C better. The WW has much less pressure drop than the TDX at equal performance, that being 1GPM for the WW (20") and 1.75 for the TDX (43.2") I wouldn't think that the wye fitting was too much of a hassle.

In case you're going to bring up your system, I'd like to point out now that you got 3.05GPM through the TDX, making your pump provide 3.05GPM @ more than 10.9' H2O, making your pump abnormally powerful.

overclockers.com used different accelerator plates on their RBX and TDX reviews. I believe a higher restriction plate (#4 vs #1) was used on the TDX so it makes it hard to use their data to calculate the different relative performance/pressure drops of the two blocks.

AngryAlpaca, the pump that pHaestus has is a hydrothruster. Yes it IS strong. Some of that is needed to overcome the pressure drop from all the instrumentation. Some of it is probably because pHaestus likes to have a big pump. :D

I'd like to know how the silver version performs, I "think" that's been asked here, but people aren't clear enough with their "that's" for me to be sure.

So how does the silver version perform?

I dunno only one I've seen is at pimprig. I believe the RBX designer (ROKK?) said 3C somewhere for silver vs copper rbx, but that smacks of foolishness to me.

The physics roughly says that just changing from C110 copper to pure silver that a difference of around 0.002-0.004C/W (at best) should be expected (depending on actual purity of the copper and other factors).

Can that quote from ROKK be dug up btw? I never saw the statement but just heard that secondhand.

It was originally mentioned in this thread:

Interesting interaction going on between Zenzzo (reviewer of the Silver TDX) and Rokk here:

They make a pretty big deal out of that zenzzo fellow having a "lucky" CPU. No real details there just the fact that new stuff is coming though.
