VapoChill Micro High End

wah?? negative temps for only 50 buks?! something doesnt sound rite.. but if its tru.. i want 1! i currently have a xp90 myself
 
I don't see how you could possible get sub-ambient temps with that. It looks like a modified heatpipe to me. You can't achieve sub-ambient temps without having to actively take energy away from the system through the use of a compressor or other means. But, I may be wrong , tell us your results.
 
From what it looks it's the refrigerant that makes the difference in this case. Time will only tell....[H] team attack! :p.
 
"The cooler is similar in function to a heatpipe, with a metal base being filled with gas that heats up and rises and is then cooled by the fins and the fan. Initial performance indications suggest that it will be cooler than a Zalman CNPS770-Cu by around 7 degrees, and cooler than the reference Intel LGA775 solution by 8 degrees."

bit-tech

This is not going to do 10C. It might hit 22C, which is still killer. It's a HSF that might get temperatures lower than ambient.
 
I think the zalman is better than the refrence intel by more the 1C but I may be wrong. Sub-ambient is not posible.

Sub-ambient is possible. If it does, in fact, use evaporative cooling within the HS, then it is possible and probable.
 
Well, if they do go subambient, there would need to be some kind of condensation proofing, which has been absent in all the shots I've seen of it so far.
As I understand compression based refrigeration, the way you get the energy to move from one area to another is by varying the pressure of the refrigerant so it changes phase in different parts of the refrigeration system.
The difference in pressure is considerable. My chiller system has high side pressures of around 200 lbs, and low side pressure between 0-5 lbs, sometimes dropping into vaccum. I don't see how the microchill can achieve those kinds of pressure differences without a compressor.
Maybe vapochill is just making their own heatpipe cooler and branding it with the vapochill name, hoping the positive image their compressor systems have will sell some regular heatsinks, kind of like how the WaterChill systems were not water chillers, just plain water cooling.

Question: Is moisture or water condensate a problem with the VP"Micro?"
Answer: No..because it doesn't go below the dew point, or ambient air temp.

That definetly defeats the idea of sub zero temperatures :p. Man I hope it at least out performs the XP90 :(
 
ok according to asetek the high end of this cooler, which can be preordered here will achieve temperatures around 28 degrees celsius...

for a $45 cooler it seems fishy however this thing will supposedly achieve better teperatures than a high end water cooling setup...if true im dropping the water cooling and getting one of these :p

What is the ambient temp? I could achieve 22c with a stock HSF if I lived in alaska.
 
no idea but their site lists 28 degrees celsius for the high end model...lemme c if i can dig up more information

I just bought one of those beasts. I was told that I could get negative temperatures with it. I certainly hope for $50 the dude was right! I cancelled my XP90 order for this. I'm going to be strapping this beast to a 3000+ for overclocking bliss (hopefully).

You got the right idea that MOST vapochills cool beyond negative temps, but this specific vapochill is just a glorified heatpipe HSF.

These vapochills cool beyond negative elvels, but require a lot of protection due to condensation.

I'd also be very careful leaving that thing on your mobo if you are going to let it stand vertically
 
The Danish cooler specialist Ase Tek, famous for the VapoChill systems based on compressors and WaterChill systems as liquid coolers, presented a product at CeBIT which may take the wind out of the sails of conventional solutions. VapoChill Micro is based on the VapoChill, which retails for several hundred dollars, but it is supposed to be available for much less than $40 (30 euros). With over 130 W of power dissipation capabilities, the device is also said to be able to accommodate the cooling needs of upcoming processor generations. According to André Eriksen, CEO of AseTek, larger designs could also dissipate well over 200 W.

The device utilizes a liquid coolant that is placed in a closed circuit and transformed into a gaseous state by the waste heat of the object being cooled, which is usually a processor. This gas then rises to the upper area of the cooler, which is equipped with cooling fins. The gas then returns to its fluid state and flows back to the evaporator.

So far the installation of the VapoChill Micro is extremely easy, since the cooler can be fitted to all standard bases by means of various retaining clips. The cooling element can be turned by 360° and can thus be aligned according to need. An initial test in a few weeks will show how well the system actually works in practice.

from toms hardware

sounds really impressive
 
We already know it maxes out at 150W of cooling capacity. And that is probably exagerated. The Prescott puts out I believe 100W of heat. Which makes me seroiusly doubt that it will handle future generations just as well as this one. Like others have said, glorified heatpipe.
 
if they aren't saying condensation and dewpoint issues exist, then the performance must obviously be less than or equal to that. As far as being better than w/c, I'm a little doubtful, but they do claim to have a/c coolant in the heatpipe. Still, I don't see how it works like a 'fridge loop.
 
Well it'll really come down to the benchmarks once this thing is tested. I ordered mine from Kit-tronic for barely less than $50 shipped. I'm pretty excited about this though, so far Asetek has been really good about their products.
 
Yea, I am really looking forward to the benchmarks. One website said the review will be posted as soon as July 25th or 27th?

I don't think most heatpipes use the evaporative cooling methods that this apparently uses.

Isn't that what a heatpipe is? Using evaporation to move heat from one end to the other?

ya, but i think makes this different is the chamber at the bottom. instead of having a lot of metal right on top of the cpu you have a chamber full of this special gase which evaporates and then cools off. I'm not sure if this would work better, but it's pretty interesting.
 
I've always wondered how the tactic of cheap marketing diction stays so prevalent in so much advertising. It's always so glaringly obvious to me that I have to stop each time and think to myself, "Everyone who hears this knows it can't be taken at face value..... right?"
Reading this thread answers that question.

Not everything in life is too good to be true but if, at the end of it, you can't explain WHY or HOW could it really be possible, it probably isn't.

'A chamber full of gas which evaporates and then cools off' IS a heatpipe.

It sounds impressive if a description of every other heatpipe cooler in existence sounds impresive too, because all that tom's hardware paragraph does is describe a basic heatpipe.

Now this may or may not be a well designed, or even the best designed, heatsink - that remains to be seen. But either way it's just a heatpipe heatsink like any other on the market. Not revolutionary.
 
yeah but none of the other heatpipe hesf's have a vapor chamber filled with a refridgerant gas...as in the plastic box around the heatsink it self read this:

Once a commercial idea is refined, the technology developed and the final products available to the market - most innovations seem simple. In this respect the technical profile of the patented VapoChill Micro CPU cooler series is indeed simple. Nevertheless, the vapor chamber technology of the VapoChill - utilizing an evaporation process directly on the CPU - is in all its simplicity the most cost/effective and most efficient CPU cooling solution on the market. Two aspects of the VapoChill Micro puts it ahead of traditional heat pipe coolers:

1. Dramatically increased evaporation and condensation surface area.

2. Direct mounting of the evaporator
on the CPU.

These two features, however simple they may appear, is why the VapoChill Micro is the superior solution on the market.

Its not a question of opinion, it is a question of physics. No more no less.

Gas alone does not a refridgeration pump make...otherwise I could just unplug my freezer and have it still work. Which it wouldn't.
 
First of all ... the best you can probably do is get it to ambient temps. No less ...

In order to achieve any sort of extreme cooling you need to compress the gas inside and then cool it off. Without the compressor, you can forget about it.

There's no difference between using this and water. Only difference is, water won't evaporate fast enough, so they use different gas that will evaporate FAST.

It's almost impossible for such a small thing to achieve ambient or less, let alone -50C. You have to remember your case temps make a difference too.

A chamber filled with gas is all a heatpipe is. Yes, AseTek likes to constantly state the name of their particular compound over and over to make it sound like its groundbreaking, but don't let it fool you. Who knows what other heatpipe manufacturers use. Even if AseTek is the only one using R134a in their heatpipes then perhaps it will perform a little better, but it's not revolutionary.

As for the neat looking 'chamber,' it's just a change in design. It looks like does add surface area to one part of the reaction, but it's not a change in the basic function of a heatpipe. Heat passes through a layer of metal, evaporates a liquid, and Windows reports a temperature between ambient and 3 x ambient. Life goes on.

I'm not trying to say it won't be a good heatsink. Just that it is functionally the same as what's out there now.

Ya i know that, i was just saying that this dome shape at the bottom is different then the normal pipe style. Maybe theres been somehting like that already, but i dont know.
 
Our we positive there is a phase change in regular heatpipes? I know it's ammonia, but i was under the impression that it stayed a liquid the whole time. Very possibly wrong.
 
Any one have this yet or find reviews of it??? I may want one!! lol

Which one has better performance, the extreme, or the high end?
 
i think the extreme as it says the extreme is for overclockers + high end is for normal users

Yes, it's not a change in basic function, but that surface area could be critical. The heat extracted from the surroundings during a phase change is proportional to the mass of the refrigerant involved in the reaction. If having a vapor chamber as opposed to just a heatpipe allows Asetek to involve more refrigerant in the reaction, you could get a very dramatic increase in cooling performance.
 
I never say never to anything. All I want to see if the benchies for temps / loudness and what not. Seeing is beleiving. So lets see how well it does....

The reason why something like ammonia or R134a would be used is partly because they have a low boiling point, for the purpose of the phase change. Also, pipes full of a liquid would add a lot of weight and I don't think their performance would differ terribly from a solid copper bar.

Yes, that's undeniably true. But it's only a dramatic way of stating a very simple concept. There are scores of engineering companies across the globe that would love to dominate the PC cooling market (not to mention thousands of other applications) - But if simply increasing surface area was going to do it then it would have been done and duplicated long ago. The best performing heatpipe coolers now don't need 9 heatpipes to do their job - the biggest difference you see is in the size of the radiator. No matter how efficient you make one part of a the process you will be limited by all the others.

Increasing surface area is the fundamental name of the game; no product's sales ever flopped because the engineer behind it never thought to 'use more heatpipes'. The only difference between the Vapochill Micro heatpipe and any other is it's shape. It's just a single metal compartment filled with a single gaseous compound. If this product is able to beat an XP-120 by 5 or 10 percent, then it will be due a conglomeration of well thought out design features, but nothing quite so dramatic.

In idle mode, the fan has one speed while in heavy load it starts rotating faster, making a machine noisier. I believe that’s whatthe motherboard dictates to the cooler as these mobos are very smart these days and want to increase cooler RPMs once the temperature rises to a certain level.

LOL. I think the author let his 9 year old son help him out with this one.
Maybe he should have let the motherboard write the article for him. They are very smart these days.
