OCOOL Coolplex 10 LT SUCKS!!!!!!

[mele]

Came home today and it had cracked in two places and leaked all over my damn system!!!!!!

I'm glad it was near the bottom of the case away from my MB.

Its your fault. You should not have cracked the tube. What did you expect?

I don't think Alphacool products are of bulletproof quality, i don't say it's crap but it's not high end.

useless comment.

Now tell us how you cracked it

[NKrader]

if he cracked it, it would have started leaking before he walked away? so? are you just trying to irritate people today db?

i realize he could have overtightened and that could have caused the crack, but still. its not like he watched it happen.



and at op, these things happen with any company.. failures do happen.. you should expect it and not call the companies names.

prove it

Acrylic/plexi tube reservoirs crack everyday from all manufacturers. Tis the nature of the beast.

[Makymaco]

prove it

Sorry for my ealier response but i was irritated by yours.
If i follow you, you think alphacool always use a very good acrilic and he must have overtighted it with a tool so it has cracked, and it must be his fault ?

I think you get what you pay for, the EK version is twice the price for example. It's a shame watercooling products ar so pricey (and perhaps overpriced)

EK acrylic reservoirs can crack too, it just happens with acrylic! Not sure why DB is trolling.

Was about to say the same thing

[schoolslave]

Was about to say the same thing

Because that's all he ever does?

[mele]

It has been in my system for almost a year now....was hand tightened only at time of install.

[st0ned]

Dahm ! I must keep a close look at mine since it is in a really dangerous place that would utterly destroy my system if it cracks...

[GliderHR]

These actual acrylic reservoirs trend to react funny (chemical induced tension cracking) with many watercooling mixtures.
I lost five acrylic reservoirs until now. Reason: cheap produced acrylic cylinders (Alphacool, Watercool, Phobya). Old reservoirs didn't have this feature (maybe due to better mechanical treatment or due to a heat treatment after mechanical work.
I treated my actual one in my hot air oven for 4 hours at 70-80?C and this one doesn't show even on crack.
(hope my grammar is acceptable...)

My old EK high quality reservoir cracked too and is twice price

[ggdh]

EK anyone? Effect of few months in a box.



You can't feel cracks from the outside, only from inside with your fingernails.

[DarthBeavis]

I wish Martin would do some tests in a controlled environment that used different coolants but also that introduced temperature changes.

The reservoirs listed in this thread all used a screw on mechanism for the top and bottom. Has anyone had this issue from other types of top and bottom mechanisms? I wonder if the POM expanded and contracted causing the cracks?

[ZX2Slow]

I never had an issue with screw end reservoirs, I just switched to a Primochill CTR res with the compression caps. I swapped caps before I used it and noticed some cracking on the ends and have been pretty cautious about over torquing the end caps.

Its brittle plastic, not sure if there's something better. I would pay a premium for something better.

[rge]

The reservoirs where manufacturing process has been stated, use cheaper, mechanically weaker extruded acrylic, and do not anneal the ends after cutting.

If vendors used cast acrylic (fewer defects and mechanically stronger) and annealed the ends after cutting to prevent microfractures (ones that you cant see, but ultimately can lead to cracking), we would likely see fewer cracked reservoirs. But that would require raising price or lower profit margins. Lower profit margins are not going to happen in a business model, and if they think you will pay more, they would raise the price, and still sell the cheaper extruded plastic, and just rma the few broken ones.

Either cast acrylic with annealed ends or scratch resistant poly would make better reservoirs, but I wouldnt hold my breath waiting for either.

[Makymaco]

My old EK high quality reservoir cracked too and is twice price

It's a pity, my ek dual bay res is very well built and it seems of great quality

But I use only water, no funny coolant

[Martinm210]

LoL, You guys should stop running alcohol in your loops already..

just kidding.

Hard to blame any manufacturer if you run anything but distilled. Even with that I am sure all sorts of things flush out of rads and blocks from their respective manufacturing processes. I have even seen cubed acrylic reservoirs spider. My Swiftech MCres started to develope micro cracks at the glue joints after a few years.

I personally don't think anything acrylic made by anyone is bulletproof.

These cylindrical reservoirs with "Internal" threading just fail more often because the threadind induces machining stress and the internal nature puts the shell in tension. Your better bet is to buy the type that thread the acrylic tube on the outside. This still introduces machining stress, but the shell is then put in compression rather than tension (better design). IandH and a few other options use that setup. That and flush parts really well and minimize the use of coolants. I know there are also annealing processes involved, but not sure of the details.

Or stick to acetal reservoirs or a simplie tubing T line. It may not be as purdy, but less risk and cost.

Bling comes with risk and maintenace...

[DarthBeavis]

I got maximum overclocks with this one - do not see cracks

[Sparky]

My trusty old EK150 hasn't cracked yet. Got it in 2007.

That said, I've seen a few that have.

Acrylic can and does crack, particularly if stressed a certain way or subjected to some kinds of additives and such. Not sure why the OPs cracked. How thick is the acrylic on those?

I think the OP needs a few more exclamation points for stronger effect.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Lol

[avddreamr]

I had my ek 150 crack after extensive use with DISTILLED water, on a system that spends most of it's life idle, and not overclocked.
