BigAkita has a new review up on some new coolers which look to include the new top dog in silent cooling. These Asetek Micro coolers are impressive to say the least.


Check it out here.

So basically, its a heatcore filled with pressurized gas that condense's when heated to form a liquid, the liquid then flows through the heatcore which gets cooled off and goes to the part that touches the CPU...

Cool though. To me at first, it looked like a picture frame or something you put on yourdesk!

Did you use the FanMate that comes with the Zalman? If so, what RPM did you run the Zalman at to get the scores in your review.

Oh yeah, thanks for including the Zalman in your review.

The scores were all done with the fans wide open. I ran the Zalman off the CPU header after disabling the motherboards control feature. I just told it to run max when temp reaches 25C.

Nerdz, you have that backwards. It has a low boiling point so the liquid is heated to a vapor which goes up to the core where it is cooled back to liquid and gravity takes it back down to the CPU to start all over again. No different than Phase Change cooling except there is a lot less coolant and no condenser.

Intresting, I had wondered how this would perform when I first caught a glimpse of it , being on par with the Zally is a good starting point, I think they could have true "Top Gun" performance with a few of the minor tweeks you suggested

Great review, awesome pictures!

As always BA.

Il sick to a proven design I think. That think is just to bulky for my tastes. I like Zalman, even more so ThermalRight.

Im pretty sure you might have gotten somthin mixed up somewhere in there, cause in my book 47db isnt really all that quiet, and @ 35cfm

But on an upper note that was a great review, i like that it was light, didnt hog up cpu area and had great cooling for the cpu and the ram on the back of video cards, but the noise kinda throws me off a little.

Good catch, Beachbum. I must have been looking at one set of numbers while typing another. The actual dB is 28dBA @ 35CFM. Rep at ya for catching that. I'll ask GK to change it.

Haha I saw that, but I have seen site where they mesure the dB themselves closer to the fan to get the "real" sound created. Not the brands rating, usually 3ft away.

28db damn now thats more like it,
so do you think a 92-120mm adapter would fit on there to attatch a high cfm fan...? that way i could put on a talerable 32db 79cfm fan and possably got those temps knocked down 3-5deg?
thanx.

POST #200

I think it would be a breeze to fashion another shroud to accomodate a 120mm Fan. I just don't see it happening for me anytime soon due to other review deadlines.

Your review was one of the best that I had read and I recently purchased the unit based upon your review. It was one of the few who seemed to give an honest appraisal of the VapoChill Micro and provide clear pictures of the unit.

Having purchased the VapoChill I ran into a few problems. Although the instructions came with the unit they were not very clear to me and may not be clear to others who read your review. Three questions that I believe that I may share with other consumers who purchase the unit are:

1) Which way does the fan go? Is it with the logo facing outwards or towards the radiator? The instructions didn't say.

2) The small black pushpins, do you first take them apart, insert the top half through the fan and shroud and lock with the bottom half? Or, push the whole unit through the fan into the shroud hole? Again, the instructions don't say. In fact, I wouldn't have even known the black screws came apart if I hadn't been playing with it.

3) If you decide the unit is not for you...how do you remove the VCM clip from the motherboard? Again, no instructions came with the unit or is available on the website. (ASUS 775 motherboard)

I know these sound like rookie questions but I'm like many consumers out there and I appreciate any advice to avoid problems that I can get. And, when I get into trouble I appreciate all the help I can get. 8)

BTW: I really would like to know the answer to the above questions. 8)

Thanks!

Just wanted to welcome you aboard to PimpRig, Midnight Storm it is going to be great one my freind, Thrasher2 should be along soon with his welcome greetings and very helpful links for you to check out. You have come to what i have found to be one of the best site to learn how mod and find out problems with your computers and other great things. You will also find out alot of fello pimps and pimpets are here that will try to help you out with any kind modding and pc problems you might have. Great to have you aboard Midnight Storm hope you enjoy the site.....

MS, good questions and let me answer them for you.

1. The logo faces out which makes the airflow go towards the aluminum fins.

2. You don't have to take them apart, all you have to do is pull the center slight out to allow the sleeve to close a bit then it will slip through the holes. After you remove them several times you may find that the sleeves have expanded, then you may have to remove them completely for installation.

3. All you need to do is squeeze the base of the pins together on the bottom of the motherboard and push them back up. This will require removing the motherboard from the case.

Hello
First thank you for your prompt response. I appreciate you taking the time to do so. You know one of the things I enjoyed about your review -- that other reviewers don't do -- is that you didn't seem to pull any punches.

You were curious about the fan, researched it, found out info and provided that info. I was curious myself but none of the other reviewers seem to go into as much depth as you did. They seem to just get the product, install it, and give a canned review of what the manufacture's press release said.

Anyway, thank you for your response

Storm
P.S. One quick question, which way would the arrows be turned before I pinch the bottom? And, can I use a pair of pliers or would you suggest not? Thanks!

The arrow direction of the pins shouldn't matter. Unfortunately, I haven't had the pleasure of doing a 775 mount with this setup, so I am honestly just going from experience. A needlenose pliers works well but just ensure you use a light touch.

For BA, my buddy just got one for his 3500+ s939. and it works great. lowered cpu temps by 9c @ load

welcome to PR midnightstorm, if your looking for some kickbutt reviews than BA is the dude to fallow.
and you should be seeing thrasher soon.

I think you meant no Compressor bro....The unit clearly has an Evaporator and a Condensor. It just doesn't use a compressor to move the liquid/ gas...It uses gravity and heat from the Evaporator...

Looking at your review...
It was extremly informative. This unit gives me the impression that it's great engineering that could have been assembled a little better eh...However the numbers appear on par. Maybe had they spent a few more mins on the details they would have overtaken the ZALMAN.

I would really be curious to see how this performs with a higher CFM fan with lower noise. Something 120 like the king ZALLYS have.

Actually, I meant condensor. As you know, in phase change cooling on a large scale, there is a large radiator separate from the rest of the system that the cooling solution runs through to cool it enough so that it changes from a gas back to a liquid. In heatpipes, that cooling happens as the gas reaches the uppermost part of the pipe away from the heat source and then is usually returned to the heat source via capillary inserts. The fan assists with the cooling process, but a good heatpipe will still cool without a fan. A phase change won't cool without the condensor.

You are correct though, there is no compressor either. Most heatpipes depend on gravity. Now, I will get some arguments here that the tubes are vacuum sealed so gravity isn't a factor, but I will tell them from experience that I have only run across a couple heatpipes that were truly vacuum sealed. All the others were affected by the orientation. My current heatpipe review is one of the exceptions that have actual vacuum sealed tubes so the orientation doesn't affect it.
