Prometiea or VapoChill
 

I'm considering switching from water to vapour and I can get a Prometiea Mach1 for about the same price as a new model VapoChill. In reading the installation procedures, the Prometeia uses no dielectric grease, while with the VapoChill you have to slather it on everywhere, even with a heating element in the back. Anyone know why? Any recommendations one over the other?

u know you could build you own type of prometia system...?

Well yeah, I could probably build my own thermonuclear device given enough time............what's your point?

Prometeia is a bit more powerful than the VapoChill.
You can also switch to a more r404a rich gas mix for that "extra freeze power".

It also has a better mounting block, better isolation (thus less need for grease or sealants, and it's bit more efficient at it, as far as i know. Or, you can try a Kryo (which is good too), but personally, i wouldnt go for the Vapo.

The point of having a heating element is to keep the processor from dropping temps too fast at start. It can damage the core if it does.

I'd suggest a Prometia.

Its already been suggested on most places that the MkI and MkII display only a 2~3deg difference between the two in cooling power. Basically the MkII has overall better user control over the MkI and better user interface.

I've had a Vapochill CE and lets put it plainly, it was about on par with a Cascade, Silverstorm4 rad and 1250. I dont know for sure if it was on par, it probably was a tad less than that in fact. But the fact that I crushed two 2500+ Bartons, one which did 2.7GHz w/ the Cascade really put me off the Vapo's mounting mechanism.

Then a mate just bought the Prometia MkII and it truly was a huge difference to the Vapo. :drool:

I can see your point with the mounting hardware, but I find it tough to accept that a VapoChill would only perform as well or worse than a decent watercooling setup. I'm not doubting your word, it's just hard to believe.

Mind you, it was a Vapochill Classic Edition, and they are rated for 120W of heat dissapation, in comparison to 140W, 160W & 180W for the SE, PE & XE models. The Prommie MkII is officially rated for 200W of heat dissipation and the Prommie MkI is only 140W from memory. However, most users say that the cooling capacity of both is approximately equal.

You ought to check out this thread in OCAU. Cathar's water setup against Stergiopolis Vapo PE. I shant say who won, but it was an interesting event to say the least.

The Prommie gets the vote from me anyday cause of their cooling efficiency and plus the mounting mechanism. Unless u're on a P4 platform than the Vapo's evap head aint too much of a worry.

Nice reply...

pfft...

next time I help someone...

Dans something is the maker of what I think vapochill uses for the condenser... And just a relay of some sort to turn on a little bit before the computer and also up and down the temp according to the temp of the cpu....

its up to you how much you wanna pay and how much of a "mod" you actually wanna do...

if your into modding that is instead of buying premade stuff...

no shame though if you got the cash... just buy it right?

Its Danfoss.

The prometeia is rated for 200W of max power. Not 140w. And both of them (mach II and mach I) have practicaly the same "heatengine". They have changed mainly the temperatura sensing equiment and monitorization from the machI to machII.

Sin22 is correct. They supply the Compressor for the Prom/ Vapo /Kryo ..and other AC type systems out there. However, they are not cheap.

And constructig your own Prom system will be up to 200-300$* US depending on costs and labour.
Personally, i'd get new one, warranty, a purty case and the assurance that it works.

*unless you know someone what works in the business , or you mod a refrigerator or freezer compressor.

It depends, the literature on the Mach I is as such.

So it does scale at max loads.

Like i said 200W at max. But that's what's important , let me explain :

In the real world, nobody i know that has a prometeia (and i know a few) are idle in windows with default settings in their machine.

They are either folding, or running some benchmarks and/or prime or similar to test new tweaks, or playing. Idle doesnt exist there.

All of them are running a Intel system at 3.7/4.0 Ghz (depends on which) . And trust me , they make the most of those 200W .

Anyway. You can (and they did) change the gas to a more rich r404a misture. You get a few degrees that way. And, you can change the condenser, or put a bigger capillary ... which also helps. So , more than 200W is achievable.

Point is, to buy a prometeia and not take advantage of it ... i dont think it's worth the money. Even more if you take in account that the sockets and mobos are already changing for A64, and probably later versions of Prescott. Unless chipcon supplys new retentions, you'll have to "mod" it yourself...

Wow, been awhile since I posted here. I just bought a VapoChill PE because they were on sale at FrozenCpu for 499. Just so you know since no one mentioned it, you can do the same r404a upgrade to the VapoChill. Most people said they have had it done for 50-75 dollars, and it usually lowers the idle temp to -45/-50 at zero load. Yeah a prometia would have been nice, but the cost isn't worth it to me for the same item (more or less). Not to mention I have a p4, so I won't be cracking a core. I plan on switching to an AMD64/FX chip, later on probally, so it won't be an issue there either.

I dont remember Asetek mentioning if there will be a socket kit available for the A64/FX boards. Be careful also, I've been noticing quite a number of FX boards have the socket a fair way down, closer to the middle of the board, and I'm sure some of the evap heads just wont be able to reach it.

As to the R404a "upgrade", with the PE version, Asetek has warned people that it may or may not work. Yes I know people have done it, but due to the PE having a larger compressor, the BDF53E I think, it has trouble starting with the heavier refrigerant. Good luck though.

And hopefully Asetek will finally get the Windows software out. Its a dream being able to control most of the settings within windows.

True, they are working on the a64/fx kit. Its coming though. So far initial reports about upgrading to 404a have all been good. I've seen a couple the didn't work, but it was usually because they put to much of a charge in. No harm done though, they just vacum it back out and its ready to roll again.

Windows software is out in beta, and its working pretty well right now. Hit there forums for the download.

Thats good to know.

I've already sold my Vapo anyhows. Was all good fun, but somehow the lure of water is stronger :D

I love water cooling, but I've been doing it for so many years now, its time for the next step. : )
