duron, had jij geen beschermend materiaal enzo?

btw: hoeveel plaats neemt jouw koelsysteem dan in?

DUR0N 30th May 2002 22:12

bescherming is voor wussies ;) nee, ik ga da vanachter in mijn tuin doen, en met materiaal op afstand :) eens dat alle leidingen terug dicht zijn, is er geen gevaar meer (tenzij ge lomp zijt)

plaats: ongeveer een EVA unit, gaat toch nooit ingebouwt worden

ff Gibbo quoten over de Prometeia...
Quote:

Hi there

First of all Intel warranty covers the CPU, so it will be replaced by our distributor, as there was no physically damage evident to the processor.
Just wish you had come to me sooner Slim, as it would have been nice to see what your 1.6 that did 2.9 air cooled was capable of when running at approx 40-50c cooler (10c-15c loaded temps).

Now as I have had PLENTY of experience with the Vapochill, I can fairly compare the two.

I know that practically everybody that had a Vapochill socket A kit manage to kill a CPU or several, I was lucky to have several years experience, as we both got along fine.
I thought the Vapochill was of poor quality, mainly the case, but after setting up and installing Slims Prometeia the Vapochill is definetely a better made and engineered product.
Unfortunately I never tried the Vapo with a P4, but was told that the P4 socket kit was very good quality, and that it also did a fine job at cooling.
Also the Vapochill does have a well illustrated manual, even though I never needed to read it.

The Prometeia socket kit in my view is terrible, and they quite frankly have not done enough testing with different motherboard and configurations. The manual is also poor, and on this side of things they need to do more research.
The case is awful, yes worse than the Vapo, and it's probably something you would get at the computer fair for approx £15 with PSU, anyway forget the case.

I was impressed that the Prometeia had a fare length of capillary tubing (hose), and using the unit with other case would not be a problem. The evaporator temp display is in a bad position, and hard to view.

When it came to fitting the unit, even though awkward I had no problem, but I have plenty of experience from Vapochill's, I have fitted heatsinks 1000's of times, and I have never damaged a processor to date yet.
What I am basically saying is that a novice should not go out buying a freon based cooling unit, as basically there gonna damage their kit. I would only advise such units to users with plenty of knowledge and experience in fitting heatsinks and possibly H20 cooling.

The contact seemed pretty good, but as already suggested not using the sticky black gunk would probably help. The STD servicol compound should be capable of doing a better job.

At this moment in time, I would say the Vapo definetely has a quality edge, and possible maybe a slight performance edge.
However I do believe the Prometeia to be a more powerful solution, and once the socket kit is improved upon, or the user decises a method to increase contact pressure, performance will be improved and will surpass that of the Vapochill.

I would say for the moment, avoid until things improve and users come up with methods of improving performance for themselves.

Good luck with it Slim!
denk dat het een goede eerste indruk is van een rot in het vak (die spijtig genoeg wel min of meer gestopt, naar ik gehoord heb?)

dat ziet er niet zo leuk uit voor iemand die juust een 700 euro cooling unit besteld heeft...
zucht...

maar JC zijn temps zijn dan weer wel goed...
ben nu aan het testen geslagen, paar opmerkingen van chip-con zelf uitgeprobeerd...sebiet nekee zonder een deel van de isolatie werken om nog beter contact te krijgen.
Chip-Con zelf zei dat dat pr0lly mijn probleem...
Volgens mij kennen ze het probleem onderhand wel...

The Senile Doctor 31st May 2002 15:03

test away... tegen de tijd dat ik ze hbe, zijn jullie x-perts

:ws:

fredperry 31st May 2002 17:41

waarschijnlijk ;)

en ik vind het systeem redelijk gemakkelijk om regelmatig van cpu te verwisselen; duurt iets langer als een simpele aircooler, maar sneller als een wb block in mijn ogen, das ook een pluspunt ;)

Ik ben nu op zoek naar iets dat isoleert, maar nie zo'n groot volume heeft zoals dat zwarte spul van chip-con...
heb nu dat zwarte spul iets kleiner gemaakt en temps zijn paar graden gezakt (2-3), dus als ik dat zou wegnemen, kan ik - hoop ik - deftige temps bereiken, ma moet dan ik wel een manier vinden om te isoleren...µ



edit: heb contact met een prometeia gebruiker in de UK, die tot voor kort temps van ... 20°C haalde met een Intel P4 :wtf:

maar door dat zwarte spul ervan tussen te laten en te vervangen door iets minder volumineus zakten zijn temps tot ... -15°C :wtf:
(beide idle)
(kan toch nog wat beter, gezien de kracht van de compressor)

DUR0N 31st May 2002 21:09

no way... zeker iets met de temp sensor. 35°C verschil is wel wat teveel van het goede.
hebbe oude figo's over het algemmen nen deftige compressor?

fredperry 31st May 2002 21:11

als het nen Danfoss is zitte goed, L'unite hermetique is ook wel goed hebben ze mij gezegd.

wel zien dat hij proper is, want das belangrijk en ook geen vocht...

voor de rest typenummer is opschrijven en nakijken of hij genoeg watt kan koelen.

om u gerust te stellen:
heb de andere prometeia-users in het oog gehouden en heb met sommigen regelmatig contact en na de aanpassingen zijn de temps in de goede zin geëvolueerd:

Well I think that fredperry's problem isn't really a problem... the suface area of an Athlon is pretty small, and if you use the extra rings supplied with the kit to have a bit more pressure, the CPU contact is pretty good. I'm getting awesome temps now after I mounted everything properly... this is a die hard cooling solution, so I'm not too bothered about the case not looking great. If you're crazy about overclocking and getting the last drop of performance out of your rig, who cares about what the case looks like....
Misschien dat de jouwe toch prima werkt, maar dat het enkel stukken slechter koelt op zo'n kleine core. Alhoewel, 't is wel een inmens groot verschil...

fredperry 1st June 2002 20:51

idd lijkt me toch nog een te groot verschil...

daarom, ik zou wa meer tijd moeten hebben en iets moeten horen van petrus vanop icronticforums...die ging, d8 ik toch, zijne prometeia ook voor nen AMD gebruiken.

ik zou dielectric grease moeten hebben, daarmee mijn mobo extra isoleren, en dan da zwart spul is weglaten en langst den buitenkant plakken.
Alleen, ik heb wa schrik om de core te crushen

DUR0N 1st June 2002 21:51

bwaa, ge moet daarmee oppassen dat ge uw core niet crush, maar ook niet teveel. Een dikke alpha die erop hangt is ook veel gewicht, en dan als je hem monteert moet je ook die vijzen vrij hard aandraaien. :wtf2:

RichBa5tard 1st June 2002 22:01

Mja, maar 'k denk dat het veel eenvoudiger is om een loodzware HS er loodrecht op te plaatsen dan een evap met zo'n zware slang eraan. :)

jASjE 1st June 2002 22:07

een pal8045 hangt ook rechtstreeks op het moederbord hé, is een stuk safer in my humble opinion..

DUR0N 1st June 2002 23:04

neen, maar er zit ook vrij veel druk op, over de moeilijkheid van de instalatie van een phase change setup gaan we mar zwijgen :)

k'had den eerste keer ook schrik om nen alpha er te vast op te vijzen, en twas niet eens mijne pc. Alles is gelukkig goed afgelopen :gay:

point: maak u niet TE druk op ..euh.. de druk

fredperry 2nd June 2002 06:42

ik heb woensdag C++ en daarna zijn er enkele weken theorievakken waarvoor ik niet echt een pc nodig heb, dus kan ik woensdag nog wat testen...
Op dit moment kan ik het mij niet veroorloven zonder pc te zitten :(

geen backup systeem? ik heb ier altijd wel een 468 uitgerust om wat te surfen/leren ;)
C++ zou wel lang duren :/

fredperry 2nd June 2002 09:49

mja nen AMD k6-2 333
en nen 486

ma voor C++, dunno zenne
na C++ volstaan die als backup
dus woensdag heb ik ne namiddag tijd :D

fredperry 3rd June 2002 21:21

update: heb net deze mail gekregen van chip-con:

Quote:

It does sound as if this is still not right.

Perhaps you can try this trick instead.

Take off the Coolinghead, and clean the top the mounting bracket and
the Coolinghead, to start on a fresh mount between the two.

Now put on the Coolinghead again without any Sealstring in between, and
do place a couple of extra spacers on each screw. Finally make a string
of sealsring by twisting to strings together into one, and then place
this around the GAP between the head and the bracket. Be sure it covers
the gap entirely, and then start the system up again. This should
guarantee proper thermal contact between the Core and the Coolinghead.

The noise you hear is due to insufficient load of the Cooling System,
when liquid comes back into a lttle pot inside the Compressor. This
Compressor has indirect suction, and therefore you do not need to worry
about any potential damage inside the Compressor. However the unevaporated
R134 that returns to this pot, obviously evaporates very quickly down
there, due to the extra heat, that is what generates this noise under
insufficient load.

This is also what makes me believe that your thermal contact is not
good enough.

I hope this clears your questions, and once again sorry for the slow
responce.

Looking forward to hearing from you again, with hopefully some better
Cooling results.
behulpzame mensen...

Allee, kzal mij woensdag kunnen amuseren ;)

jmke 3rd June 2002 21:35

zeker ons informeren ;-)

leuk wel iemand die alles al eens testdraait , weten we waar de mankementen zitten ;)

The Senile Doctor 5th June 2002 09:27

I have just received word that the prometheia unit has been shipped.

These guys are simply the best when it comes to keeping you informed or answering questions.

Danish blokes rule!

biCker 5th June 2002 09:40

Let's hope UPS won't go on strike then!

poloke's prometeia is also been shipped today...so that makes two AMD's cooled by prometeia and two Intel cooled by prometeia in belgium, and gilles prometeia is also ont the way (and there is another belgian dude who ordered it, but I dunno who)

DUR0N 5th June 2002 16:11

I'm just wondering: what if Colruyt (=belgian supermarket, always the cheapest in quality products ;) ) sold/replaced their refrigerators? Those professional stuff goes below -40°C in the freezer itself, so what would it be as a cooling unit?
In every store there are at least 10 of them, and they prolly need to be replaced once in a wile :)

fredperry 5th June 2002 17:56

Update: left the insulation out and instead of putting it between the cooling head and the bracket on the mobo, I just put it around the gap.
But, no improvement in the temps (maybe slight of 1-2°C, but not more)

So I'm dissapointed :(:(:(
Gues I'll have to go Intel to get negative idle temps...


Second drawback: My vidcard suddenly gave up on me :(
So I'm using a S3virge (4mb?) at the moment :(

so, if you haven't got negative temps, you aren't satisfied? :D
OPP runs his system at 2-10°C, whats the problem?

sorry to hear that, might be the extra voltage you added...

fredperry 5th June 2002 18:31

OPPs temps:



Mine:



Lesser volts and lesser speed...

The Senile Doctor 5th June 2002 18:43

was that on the eva?

OPPAINTER 5th June 2002 18:45

fredperry,

My max temps are around 10c with the above clock and voltage.
As for yours at that speed and voltage it does seem a bit High, could be your not seated perfect. Also with useing the Mobo socket probe it can differ, your probe may be up or down from the bottom of the chip resulting in different temps.
The bottom line and result from your cooler is Can your chip overclock very good with it?:D

OPP

The Senile Doctor 5th June 2002 19:05

that's what we keep asking him... he doesn't respond:D

can or can you not overclock any higher?
anywayz, we'll be seeing a lot of prometheia results here in the next few weeks as some 6 or seven people in Belgium have one or will get one in the next week or so.


fredperry 5th June 2002 19:19

Well, about the oc'ing: something is stopping me, dunno what, maybe my NIC (realtek), vidcard...
but due to my exams I've got little time on my hands (but I'll give it another shot ;))

about the temps: my EPoX 8K7A+ is quite old, so prolly it is the mobo socket probe that makes the difference...(at least I hope so ;))

OPPAINTER 5th June 2002 19:41

what are the evaporator temps reading?

OPP

fredperry 5th June 2002 20:37

idling at -31°C, cpu = 6°C, 2.05v Vcore

OPPAINTER 5th June 2002 20:42

At -31 and your only at 6c, you should be more like -6c, there has to be a seating problem.

OPP

I know, but I tried several things, one of them being putting the evaporator on without any insulation that could be in the way, and put the insulation afterwards on it.
Now the screws can be mounted with extra spacers, now I only received three, and chip-con told me you can use up to five (!).

So my next test will be to put some extra spacers on (if i can find some suitable ones in my local hardware store (metal and wood shop I mean ;))

The Senile Doctor 5th June 2002 20:52

Just be careful you don't f**k up your athlon,
you've been having lots of misfortune these last few days...

I'm quite curious to see what mine will give when I receive it... how many days did you wait once they sent it?
it got sent by UPS this very morning @ 6 am.

fredperry 5th June 2002 20:55

about the athlon: chip-con supplied a home-made shim with it, and since I'm a screw-up normally, it's working ;)

And good support from chip-con too, quick, friendly and they know their stuff ;)

It was send the 24th and I got it the 28th (+/-)

OPPAINTER 5th June 2002 21:00

I'll tell you about this MX mounting on AMD, acording to the Directions My chip would have made very little contact to the evaportor. I had to tighten it down more, a lot more then spec'd to get good contact.
