Enzotech SCW-1 case cracked after a week of usage

[rgooch]

A friend purchased a SCW-1 from enzotech, after mounting it on cpu after a week there is cracked on the case
anyone notice the same problem?

[nikhsub1]

The top isnt metal... it is plastic. Yes pics are in order... is just the shiny bit cracked or is the block leaking?

in germany are a lot of users with crackes enzos!

It looks like the barbs were screwed in way to tight. By the shavings and where the crack took place.

[jammin]

the german knows only 7 mm!





Attention: This cooler has a little shorter threads, hence, it can come by some connections to problems that the connection presses up to the ground and does not seal then either or destroys with too strong pulling the Enzotech cooler. If the cooler is destroyed in this manner, the damage counts as a " manelle damage " and this does not fall under the guarantee. Hence, we recommend by connections with approx. 7-mm thread length still per thread 1x article. To use 95008.

looks like either they were screwed in to far/tight or the barbs themselves possibly to "long" would be my guess.

[Clockwork_Apple]

Ouch, that sucks for it to happen to an expensive block.

[Waterlogged]

they used way to much teflon tape on threads...
...gee no need when 0-ring seals just fine.

...either that or they used BSPT (tapered) fittings.

[peebee]

No we don´t use Teflon tape in germany That is only used with the UK-Thermochill Radiators and the fittings.

But the thread of most common barbs in germany have longer threads.
Ther was also another person that shortened the thread of his barbs to the length of the original enclosed barbs. (This guy is not a rookie) But it also cracked the Enzo.
No idea why that happened.

I also had the Enzo for a little testing, and the material/quality of the top is not very promising. Remove it and you will feel what I mean.

[Exahertz]

ouch...

Is that delrin? seems awfully brittle.

maybe it wasnt tapped all the way down to the bottom and the threads of the barb started pushing into it??? is there a step at the bottom? there shouldnt be a step as i would think that would cause a little resistance or turblance).
does anyone know of a drawing with the dimensions for the Enzotechs?

[Waterlogged]

I did a bit of digging through some of the old topics here and found a post that had a tasty morsel in it.

If you look at the first pic on that page, it looks like the top is injection molded delrin which is a little bit weaker than it's machined counterpart, but what I find most telling, is the area where this is happening, look at how thin it looks.

[CedricFP]

This is bad for Enzotech.

[Xilikon]

Yes, another reason to not buy it. It's unfortunate for such a good looking block.

[Liquid3D]

So far I haven't seen this problem, however; I used the 1/2" barbs supplied and didn't over-tighten. I've leraned that water-block fittings just need to be tight enough for a seal, not screwed to the Black Hole point. This is not to say I don't agree I think the top sections are simply injection molded pastic.

Although I must say with a high pressure/flow rate pump it does erfrom very well. I've taken the block apart below.

I'm finishing up a 5-way shoot out including the Sapphire SCW-1, Danger Den Copper TDX, Koolance CPU330, Swiftech Agpogee GT and Apogee GTX.. The first pioc below compares base-plate thinkness, with the Sapphire on top of the Apogee GTX. Seems almost every block-maker in the business is using this thickness, and employing a flat (extrudud pin) copper base onot which the rest of the block is bolted. Some use cross flow, others direct impingement. For the most part Direct Impingement out performs cross channel IF a high pressure/flow rate pump is used...

My round-up uses the LAING D5-38 Vario, triple 120mm Rad., DD Bay res, in a workstation environment (no temp differential between a building internal case temp and ambient). The heat source is a Q6600 using Toture Test Prime 25.5 (one of only two programs I know of currently able to stress all four cores).

Interesting choices. Just what you could get?

Comparison shoot out without D-tek Fusion?

[Nate P.]

I bet if someone made replacement tops for the Enzotech they would make a lot of money (Martin, Iandh, I'm looking at you).

Umm, why?

[Nate P.]

Umm, why?

Because the stock tops are cheap plastic that evidently cracks easily. A delrin or copper top would not only look better but would crack less easily I guess.

But the blocks dont perform that well. And guess what? The tops are delrin.

Ah, I didn't know that. And I thought the blocks were actually decent. Shows how much I know.

[Xilikon]

I don't think the material is a problem but more likely a design flaw.

EDIT: D-Tek Fuzion en-route

I can't give away the results yet, but suffice it to say Danger Den's ole Copper-TDX may surprise you and I'm sure its because this block hasn't gone the route most WB makers have.

The most commonly employed mass produced design, now in use by almost every block maker out there is the thin base - extruded pin (of varying shapes). The extruded pin gives you the most bang for your buck in mass production.

Here's my take on the Enzo cracking problem. All they need to do is supply more specific instructions. I beleive the cracks is the result of the installation. The End-user must slide one tube over one barb and then tighten the band. Only then can you slip the second tube over the second barb and then tighten it that band. Trying to slide both tubes on then tighten those bands or any other method will stress the outer barb resulting in eventual or immediate cracking. Over tightening the barbs would be another cause of cracking.

Now I do think the barbs should be further apart, that would require re-designing the entire block. Should the block be larger anyway? Well were supposed to be shrinking our dies and their getting larger. It doesn't matter how many cores there are, the ethos of micro-computing is the micro. Making it smaller, faster, better, cheaper.

Below are some pics of the closeness of the EnzoTech barbs (The only way to mount the tubing is to do one barb at a time tighten then the next) and TDX vs Enzo base designs.
