Cooler Express "Hydra" SLI Phase Change Triple Evaporator

[Visioneer]

What do you guys think of this (http://www.frozencpu.com/cas-339.html?mv_pc=711)

[MeltedDuron]

uhm... wow, commercial triple head, I wanna see real world performance from that bad boy. nice find Visioneer

[Vapor]

Wow, the advertised temps are insane....those gotta be evap temps.

[Aphex_Tom_9]

wow, at first i was like "oh, another triple evap, cool..." but this is a retail unit in a prometeia-sized box! I think it should be $1.5K though, say 500 per head?

[SoddemFX]

If thats the same unit i read about a few months ago the 15cc SC series with r410 will be strong.

...but imagine what system you could build for $2000 including tooling.

[epion2985]

Looks like crap, I want to see some tests. The temperatures they give are evap no load no dought. Under load the temps will go up to -20C and the ballance will be all outof wack between the heads. And you still will be $2000 in the hole and feeling stupid. For 2k I would take a good chiller anyday, which is ironicaly what I am doing right now lol.

[Athens[2004]]

The Price for 3 evaps powerfullcompressor and factory job <-[controller-lcd-case] is good. And dont forget this deal guys is for people who dont have tools - skills , time.

[Entsafter]

You can buy the same cooling unit @ ebay for 999 Euro....Link (http://cgi.ebay.de/Cooler-Express-Hydra-SLI-Phase-Change-Triple-Evap_W0QQitemZ6874892570QQcategoryZ3673QQrdZ1QQcmd ZViewItem)

[epion2985]

lol, even for 999 euro the preformance and balancing is probbably ass.

[SexyMF]

Nice package..pricy but expected. Althought I reckon you should get a free t-shirt with it(and maybe some of those mints)

:)

[npk]

Yeah looks good but i´d like to see real some world testing, put 2 x1900 and a powerful cpu (300+watts) and we´ll see if it can reach the temps stated on that website.

[Jort]

300+watts lol you kidding right?

[npk]

Sorry I meant a total of 300 watts, both video cards and cpu combined power. Does it make sense now?

[npk]

oooppss sorry my bad :p: , didn´t read the config used for the testing:

Performance Test:

CPU: AMD FX-57 3.0GHz
GPU1: nVidia 7800GT
GPU2: nVidia 7800GT

[epion2985]

lol I didnt notice their test numbers untill now. I dont really trust their tests but they are still very poor. This is a joke of a system for $2000 :down:


CPU Running Prime 95 for 30 min: -34°C
GPU1 Running 3DMark for 30min: -27°C
GPU1 Running 3DMark for 30min: -28°C

Just wait untill you get a good overclock and the temps will look like this:

CPU Running Prime 95 for 30 min: -23°C
GPU1 Running 3DMark for 30min: -18°C
GPU1 Running 3DMark for 30min: -17°C

Epion was does everything I read seem negative? For a triple head, on one compressor, those are quite good temps.

[the_new_guy]

it is using a 404a compressor with 410 that cannot be good.

[Jort]

lol you guys are amazing. think about a NL11F(R134a) and R404 or R507?

NL11F max pressure is 15 bar aka 55° (absulute max is 60° for long therm and 70° for short therm)
R404a & R507 @ 45° is 15bar

19~20 bar with R410 and 32° condensing

Max pressure in a R404A compressor is 20bar

[the_new_guy]

oh! i was under the impression that 410 ran at much higher pressure 25-27 Bars

r507 compressor can handle almost 30bar :slap: btw, I've tested it :D

I think the unit looks a bit like it's build by an amateur:

Hey Unknonw, did you look at the compressor exit when doing the testing? i´d like to know how they solved the 1-3 split for the cpu and gpu evaporators (sorry for the crappy description). Do you have any picture of it?

[TodB]

I don't think that the -89C/-14C is a typo..... cuz if you check the single evap config..... FX57@3GHz with 1.45V.... evap -51C.... core -4C.... I think it's on the same mobo... soo...... it's not ok for me...

[C-BuZz]

CPU Starting Prime 95: -36°C
CPU Running Prime 95 for 30 min: -34°C

Cpu drops 2c under full load? I dont think so somehow...

I didn't test this cooler, I don't have it. I meant I tested a r507 compressor up to 30bar.

As you can see in the picture they just put 3 cappilairs in the dryer.

[LeSnip3R]

I don't think so, because with capilars you wouldn't have the same qty of liquid inside the evaps, because of gravity etc... you will have an evap much loaded than another...
Maybe 3 CPEV well tunned, or 3 TEV...

[npk]

Or perhaps it´s just poorly built? I´d like to know how they did it though. It looks like 3 capillars in the dryer just like unknown said.

[jinu117]

What it can handle and what i can handle is 2 separate story. People don't make stuff without safety and longevity of equipment I hope.
That out of way, I am guessing real problem is the gas they used... R410a. My gut feeling tells me they don't condense enough volume of it with the size of cooler to get it really... Probably R507, etc with lower Tc Tp gas might be more suitable to increase performance is my guess. Won't know till I try it though I guess :")
BTW, I don't think temperature is that bad. Just about 5c short of what one might expect.

[LeSnip3R]

It has mutliple cap in the dryer... but it can lead to CPEVs...
Sometime to shorten the lengh of capillars, you can put 2*1.00mm diam and 1.32m instead of diam 1.5mm and 1.76m. It's just an example.

[Revv23]

huh... wonder if anyone we know is building them.

good one :D

[Jort]

offcourse you ever saw a desuperheater in a prom? vapo?
a commercial unit using a desup is just too good to be true.

if there building phase-change's they now if they use a condensor thats big enough the desup isn't needed at all.

and then all the promotion used on the forums.. :)

and there is absolutly no room for any metering device other then cauptube

I am a party pooper, sorry. Although others seem to share the non positive responce.

What I am really saying is not that it is bad, but that it is very bad for the given price. If it was a chiller that would make it alot nicer and maybe worth the price, but as it stands now :down:

[jinu117]

Wow... just realized the size of desuperheater... wonder what the static charge is with so much volume on high side -_-... especially R410a...
That desuperheater is something I try to avoid as it is rather tight wrapped with too much bend where it will actually restrict flow rate of refrigerant leaving compressor and make it work harder. But anyways, 3head for 2k isn't that bad IMHO if it is commercial product. I get the feeling though if OCZ makes it through, 3 cryo-z might fit the bill better around same temp (just guess) or better temp.

I was thinking that too. This whole desuperheater thing is way out of controll. How about a properly sized condenser, a u bend to prevent flood back to compressor (although would that even be an issue with r410, probbably wont have to much liquid to flood back to begin with) and a small flex line to dampen vibration from compressor to condenser. Walt said once a tightly bent coil will wear holes though itsel from vibration and I believe himm I have see something similar first hand.

[gclg2000]

I think its prety bogus...but i guess this type of thing is becoming more in reach now w/ 65nm cores and 45nm cores down the road...the heat loads are getting smaller..

[wdrzal]

I would bet that desuperheater disrupts the airflow off the fan so much it does more harm than good. blocking 25% of the fan.

[johann]

The choice of refrigerant, why R410??? With the load of 3 heatsources the highside pressure must be very high.

$2000 is a complete rip off imo, what makes it so expensive? 2 more evaps?

Say a normal single cost $750, add 2 more evaps and flexlines + $250 and a bigger compressor +$100, perhaps a more suitable controller +$100.

$1200??? Even $1500 would be expensive

[wdrzal]

forgot all the warrenty work they ARE going to encounter.In addition to the tubes rubing already mentioned the only thing thats worse is cap tubes that cross each other.never let a cap tube lay across another cap tupe. a little vibration and you'd think someone took a round file and filed a notch in the tube.

[epion2985]

:) Tell us more Walt!

And what about people who coil the capillary around there suction? Why not there?

No worries...check out Frozencpu's disclaimer at the bottom of the page...no warranty :slapass:

My thoughts on the temps generated by the unit:

1. Any decent FX57 can do 3ghz on phase UNDERVOLTED by a decent amount.

2. The temps reported are evap temps.

3. The reported temps are for each INDIVIDUAL head loaded BY ITSELF. If you were to load ALL the heads AT THE SAME TIME, the results would be quite different......

Good idea, didnt even think of that.

[wdrzal]

they are wraped tight enough and dont move(vibrate) also where you guys wrap them has little vibration because of the flex line & distance from compressor.
cap tubes by their self because of their thin diameter and annealed temper move and bend easily even with minimal vibration. most vibration problems come from the compressor or fan. But pulsations in the refrigerant itself can also be destructive.

Bleh, just a hunch ;)
