Mentaly`s Prometeia Experience :)

[Mentaly]

Hi all


Well just got it :), it`s all setup and compared to the Vapo it ROXXX :banana: , my vapo kept my 1600+ @ 2 gig at 38 degrees full load, (maybe somethings wrong with it)
The Prom... keeps it at -6to-7 degrees full load :), I must say i`m very impressed with the Prom... not just because of temps but because of the way you set the the coolerhead on it`s so easy, not like the vapo where the core is danger every time. On the prometia they made it so simple, in my opinion everybody would be able to do this.


Evap temp idle = -40
Evap temp load= -35
Core temp idle = -15
Core temp load=-6to-7
Room temp = 23

These readings are after 4hours full load.


Again I have no where to put pics of it all, I have used a digicam to take pics of the whole setup and temps readings at full load if, if anybody will host them it woul be very much apreciated :D so u can all see what it is made off :) I must say I give it my 10 STARS :toast:


Well I better see if the cpu can take more oc in this setup.

Edit : 1600+ @ 2100 Mhz 1.98 vcore damn I`m so impressed :)
back off cpu temp @ -4 full load, Evap temp -34.

Hi NorthernYankee



Thnx man, damn im just too over excited by this :)

[dmitriyaz]

how much is that thing cost?

[Mentaly]

Hi dmitriyaz



Well U can check it out here www.prometeia.dk price is in Euro`s.

Hi NorthernYankee


yea I think so too :), well now ill just have to wait for my KX333,
just ordered it today in UK cause it will not be available in Denmark. Damn shops here don`t know a good mobo even if it
was thrown in their face :)



Menty

[LORD]

They are pretty good results for a 1600+:)

So 2100 @1.98v that is stable, yes?
If so then that's a bonus.

I read somewhere, reports of the Prometeia having problems, they may have been wrong. I'll have to check it out some more.

[Mentaly]

Hi Lord

The 1 I got have no probs at all :) in fact I think its one of the best coolers I have ever seen not many coolers can keep those temp`s on with that speed and voltage. And the assembly system is so simple and easy, with out fear of breaking the core of the cpu.

Wow, that sounds exactly like the trouble i'm running into with my Vapochill - my load temps are around 38-40C, no matter how many times I reseat it. I'd like to get some other type of phase change setup down the road, maybe this is the route to take. I'll keep an eye out for this in the states.

[Mentaly]

Hi Neptune5k


Do you have the same problem with high temps on the vapo too,
pls write some more info on your system pls, i`m just about to contact Asetek about this issue.


Edit : well I can tell u this setup is 100 times easier to install than
the vapo is no chance of crushing the core, and temps speak for themselves if u havent checked them out here http://ny.liquidninjas.com/Pics/Prometeia/primeprometeia.JPG

Odd to hearing about high Vapo Temps!!

I have a Vapochill not currently in use, but I was running
a steady -12 to -9 fully loaded XP1800 1.98v running SETI
@1950mhz.

P.s. Nice place you have here spotted a link from Icrontic :)
glad I clicked it :)

Those are probably Evaporator Temps - completely different from teh CPU temps. :(

[PMM]

The temps I quoted were what was showing on the Vapo's
LCD, so yes I see what you mean CPU Die temp is more
likely going to poss. be higher esp considering where the
thermal probe is located.

One thing I noticed about vapo's apart from the poor
mounting system is that there is not as much pressure
as you think being exerted onto the CPU Die, I ended up
adding a rubber O'Ring to the top of the Spring that is
compressed when you clamp the head unit down.

I am hopeing to at some point in the future experiment
with making a mixed Head unit employing Water cooled
peltiers and the Vapo Chiller?

In the hope that the Peltiers will take away enough heat
that the Vapohead can keep sub-20 just need the tools
to experiment one day.

My only concern is if the Vapo-system starts pulling heat from
the peltiers instead of allowing the peltiers to take away excess
heat.

[Leo]

From everything I've seen, the temps posted here seem perfectly normal for a Vapo. Thing just doesn't take very high heat loads that well.

[PMM]

too true I have set my Vapo to 2.08v in the past and seen
the temps just spiral out of control, hits a point where it
just can't exchange the heat fast enough, have seen it settle
at about -4 full loaded for a min then just loses it until it hits
the reset point and it does not matter how many large
fans you slap on the thing either:( not had much probs
when kept to sub 2volts

[2xD]

Luv your temps.
This Prometeia is really good huh?
Think I'm gonna go for that one.

How about noise with this thing?

[calantak]

quite low.

just the inbuilt case fan/case suxx. put a nice quit case with watercooling and pelts on the vidcard above it and you have silent mayhem

check thread on intel for temps with p4... how does -19° cpu temp/-44 evaptemp @ 3.2 gig sound ;)

[Mentaly]

Hi all


Well regarding the noise of the prometeia its less noisy than a vapo thats for shure, :) and the uppercase is not so nice, but whta the heck they need to make it cheap right, so I am buying a new alucase for it, maybe the new TT serie looks cool. I`m having an electrician looking @ it right now to make a solution to ma´ke the fans run a little slower easy done he says :).



Menty

[Petrus]

I agree this thing rocks ;)

[Slim]

Indeed it does. :D

some more pics in the phase change setup sticky thread

[Mentaly]

yo Calantak



FFS nice case there, looked at it myself but its 4000 kr`s here
thats a round 500 dollars :(. but im getting a TT 6000 alucase very
nice but not Coolermaster :)

Edit : ups i thought it was this 1 u had.

[calantak]

nope it's the 410, it was about 450 euro/dollars

[|PuNiSh3R|]

Ok man.. Start spittin it out.. What is the specs on the compressor.. HP and what not..

Take some pics of the whole compressor area if you could.. also you might get better performence from this if you put another fan on that condensor. But kick some stuff over man.. i gotta know how they are getting -40C with r-134A and not having that sucker in a big vacuum.. i need to know the HP of the compressor!

[Petrus]

The Danfoss NL11F specs are:
http://clarisseau.homestead.com/files/danfoss5.gif

The Compressor case:

http://clarisseau.homestead.com/files/Prom_compressor_box_.jpg

The datasheet can be downloaded here:

http://www.danfoss.com/Compressors/pdf/datasheets/r134a_220v_50_60hz/n-series/NL11F_R134a_220V_50Hz_08-01_Cg43j202.pdf

[|PuNiSh3R|]

Ok, WTF! Why does it say no where the HP of this compressor.. By the looks it has to be a 1/20HP.. But if it's a 1/20HP Compressor I would think it impossible to get R-134A down to -40C because in order to get any refrigerant pass it's boiling point you need to have the suction side in a good vacuum and a 1/20HP compressor simply cannot do that..

I didn't know you could give a compressor more electricity too.. I mean to make it work better.. Cuz that's what they seem to do.. If it's a 1/20HP compressor then it operates at their first statement of 130W.. But then they talk about more electric going to the compressor as the heat load on it goes up.. to 150 . 175 and 22x watts.. wtf?

I'm just confused now..

[calantak]

http://users.pandora.be/guy.cnockaert1/IDLE.BMP http://users.pandora.be/guy.cnockaert1/STRESSED.BMP
roomtemp : 26°C
idle evap temp : -43°C
stressed evap temp : about -37°C/-38°C
stress= three hours of prime 100%

[DaGooch]

The motor is rated at 235 Watt which equates to 0.315013 horsepower or roughly 1/3 horsepower.

[gooFly]

what is the dimension of the evaparator-box, so that I can check wich nice looking case I could fit on top of it without too much overhang?

-
gooFly

[|PuNiSh3R|]

Gooch, how did you do that equation?

I see now.. They don't start off at 130w .. That chip or whatever that controls it goes down from 235w to save energy.. interesting.. That is still a small compressor though for 1/3HP.. I mean size wise 1/3HP is pretty big.. I guess they put that thing in a vacuum then cuz no way they could get r-134a down to -40C unless they put in R-290 as well but I doubt that would even get it down to -40C.. hmm interesting indeed..

Approximate measures:

Height (PC case plus cooling case) = 67cm
Height (cooling case) = 23cm
Depth (both cases) = 45cm
Width (both cases) = 19cm

[wite]

hey Mentaly what changes have u made to the chip controller? u must have changed it right, else u wouldt get to -40 temps.

the reason why I ask is, when i tested to set the fan to operate att full speed whenever the temp goes below -29 instead of default -25 i get allot of condensation on the top of the microfreezer, seams that the built in heating element cant coap with the fan spinning at full speed most of the time. I tried this couse it helped me get another 100mhz. ;)

this is with a t-bird 1ghz running at 1520mhz 2.1V.

[|PuNiSh3R|]

Interesting.. I find this all very interesting.. -29C sounds normal for r-134a but if they are talking about getting -40C with no load.. then that r-134a HAS to be in a vacuum.. wow.. and a 1/3HP compressor that's so small.. i'm just dazed..

But the temps are correct mine stays a -43ºC Idle and -35ºC load room at 25~26ºC

[Mentaly]

Hi all

Well Wite the temps were when i received it all standard, now i have modded it with new fans PAPST, so the noise level has fallen to almost none now its -35 no load, -33 full load.


Menty

[wite]

ok, my temp will never go below -33 if I dont change the it with the chip-controller.

Mentaly r u using the halt commando to get a lower idle temp?

That's a god idea ;) I'll try that on my other Prometeia has the Intel does not need all that cooling power and more silence is always good ;)

[Mentaly]

Hi alll


Nope no haltcommand enabled, i just use standard havent messed with the Chillcontroller either.

Petrus: Well it didnt lower my temps much putting new fans on it,
only the nosie level, and my 1600+ @ 2050 mhz 1.92 vcore,
must be putting out some serious wattage :).

[PiLsY]

Mentaly,

How easy was it to get to the fans? Ive got a pair of 190cfm delta 120mms here waiting for it :D.

Also - how much "play" is there in the tubing to the radiators? Im thinking of relocating the lot into a custom case so I can put papst's on one side of the rad and the deltas on the other. Rig up a switch so I can use it day to day in silence with only the papst's on and then turn them off and the deltas on for benching.

Thx,

PiLsY.

[Mentaly]

Hi Pilsy


Very easy to get to the fans but not much room to get them out :D. Well not too much play in the tubing I would say if understand you correctly :).

There is a new review of the Prometeia up by JCviggen here:

http://www.thenakedreview.com/index.php?p=showarticle&id=81

[Neptune5k]

Anyone know how i can get one of these in the States?

[busaganashi]

They will be available in forth quarter 2002.

[|PuNiSh3R|]

Why not just put those 192CFM fans in with rheostats? keep everything in place.. turn them down.. when you bench.. crank them.. It's not really needed though.. there is only so much cooling that you can do with air on a condensor.. So you could put 5 192CFM fans on the condensor and not get any better temps.. It's not like with water cooling.. 192CFM is over kill anyway.. You don't need more then 100CFM going on that radiator.. it's only a 2 pass condensor anyway..

Granted.. once your CPU starts to heat up.. the condensor gets warmer.. cuz the more heatload you put on the liquid freon in the evaporator.. the compressor also warms up because of this.. But you still don't need 2 192CFM fans going full speed :)
