REVIEW
Kick ass.. I want one...
Arctic Cooling Accelero X2 is available here now, but i think i'm gonna wait for VF900 instead. This thing looks awesome. :slobber:
It won't be very impressive. The heatpipes don't look effective at all.
Is it enough for GeForce 7900GTX?
depends atm nothing is really known about the heat production of the 7900.Quote:

I wonder why heatpipes don`t look efective ? Remember that it`s NOT important how they are situated, cos it`s vacuum inside ;) It`s more important what kinda liquid is inside - resp. it`s boiling T
it's little brother can cool the X1900XT so I think the Big Brother should definately be able to handle that and more...Quote:

The fan blows most of the air right to the card, missing the heapipes which are situated more to the sides where less air flows. As you will know the closer the heat is taken away from the source the better. That's also the reason why heatsinks don't have 1cm thick baseplates. And don't forget that it only has 2 heatpipes, and they aren't even big. If you compare it to a high performance cpu heatsink you know what I mean, they mostly have atleast 4.Quote:

One other thing is that normally fins are often above the core area, above the heatpipes in the base. You can see this in the Thermalright heatsinks. In the Zalman there are no fins at the base so the area above the core can only loose it's heat trough the heatpipes. You can see that most of the fin surface of the cooler is totally unused as only in the small area of the fins right around the heatpipes the heat is taken away effectively, but in this case most of the air doesn't even pass this area.
I should have stated the cooler is ineffective, and not the heatpipes themself ;) They are only placed in an inefective position.Quote:

Have to agree with you alexio - yr statements are quite right. But let`s wait for the benches. IMO this one is better than VF700
the heatpipes job is to transport heat from one part of the cooler to another - they arent the cooling surface themselves. thwe design seems to removes a portion of the heat from the centre and move it to the outside edge, whilst heat will also radiate from the centre as usual. This means that the heat will come from both the middle and outside edges, which effectively increases the useful surface area, - as usually the centre is hot with the edges cooler - by having the heatpipes the heat load is spread more effectively over the heatsink - which means greater efficiency in removing the heat.
If I'm not mistaken, wasn't the design mission to make a single-slot cooler as good as the VF700, nothing more?
Also, the core contact area is scary small :fact:
Small ? Show me GPU that it won`t cover :D
i will take one
Well, they are damn good as coolingsurface themselves and the pieces of the fins very close to it.Quote:

Still even if the fins were attached to the base the heatpipes would still perform better closer to the middle, but in this case the heat isn't spread from the core so the heatpipes are totally wrong on the outer edges, but they chose this as it is impossible to manufacture this design in another way. Zalman has chosen for looks rather than performance with it's 9500 cpu cooler and now the V900.Quote:

Alexio, seeing as you don't know how it is constructed, obviously don't know the finer points of heat dissapation and are making poor observational evidence sound like a fact, why don't you wait for some reviews before making blanket statements.
Its a pet peeve of mine when people say a product is going to be rubbish before anyone expect the producers know anything about it.
Besides zalman have always gone for silence over performance in the past so I don't expect that to change now.
When is Zalman going to learn to solder the fins to the heatpipes instead of crimping them? This has been a problem with every zalman heat-pipe cooler, they lose alot of cooling due to this.
It's something thermalright realized real quick, but other companies still haven't learned....
I'm waiting ;) and please don't insult me, I know what I'm talking about. My guess is that it will be a little worse on lower power GPU's than the VF700 and a little better on the high power gpu's, but we'll see.Quote:

I know my stuff, so please don't make me look like a fool talking :banana::banana::banana::banana: :nono:
They just want to make it look nice, trust me ;)Quote:

The 7000 and 7700 cpu coolers were pretty nice, but the 9500 cooler just can't keep up with the compitition even though it's priced higher.Quote:

You mean they cool the pipes down with for example LN2 so they schrink and heat up the fins so their holes grow and make the heatpipe fit? I guessed they used this kind of technique. You're right that soldering can yield better performance if it is done right.Quote:

I don't see why the heatpipes won't work... heatpipe is meant to carry the heat from the small circular base to the fins, and the fins are cooled by the fan.
Energy transfer is CPU->base->heatpipes->fins-> fanned into the air
But of course heatpipes are only to help facilitate the movement of heat from the base to the fins. I dont see how it's wrong though... doesn't matter that no air passes over the heatpipes Alexio, they are meant to move heat as stated above - you don't need air flowing over them.
Fins are conductive but if you look at it in another way every material insulates. Heat can be taken away best as close to the heatsource which is in this case the heatpipe. So yes, air passing over the heatpipe will pick up the most heat per cm2 and after that the area just around it and so on. If this wouldn't be the case there would be no need for heatpipes. So indeed cold air flowing the closest to the heatpipe will make the deltaT the highest.Quote:

alexio is spot on, I fell for this with the zalman 9500, I should have known better since I have played around with heatsink and fans with audio amplifiers that were biased high and gave of massive heat wattage.
Basically the best cooling is always achieved when the base of the heatsink had the fins protruding dircetly from it, the same moulding or piece of metal. Using multiple bases bolted or even soldered to each other actually increases the thermal resistence at the junction. In reality the thinnest of fins always carry the heat away fastest, when these are combined with a fan the results are very good.
Fashion has lead to these trends with heatpipes in pc's when warm air should be directed out of the case. However the jucntion temp is also important,and the best approach in these situations would actuall be a 2 fan approach, one pusing air towards the junction between core and base, and another positioned nearby to pull the warm air towards a vent.
Using thick heat pipes with no fins on the base itself is not as effective. If you study that new design you will see that they are relying heavily on the heatpipes to carry the heat a considerable distance before any cooling begins.

raju now tell this to all Zalman9500/TT BT owners :rolleyes:
There are also many other coolers on the market with same construction ;)
QFT I definately agree with you.. I love my 9500 :DQuote:

I think they increased fin density from the original at CES.
nn_step and willis why you dont go to a irc channel and chat :P
waaaay off topic....
my vf700cu performs pretty nice and i think with this desing it will perform even better
If it works well and they come out with a high fan speed version, I'll get one for my upper sli card, as it runs much hotter and doesn't have a lot of space for incoming air, and i'll put my fs-v7 on the bottom card, and have two cards doing much cooler =)
I think it's too expensive... :stick: If price doesn't go down, i WILL NOT but one for sure... Am i alone ?
I did not say it didnt work, last night I reinstalled the stock amd cooler with a zalman fan pushing around 30cfm and the results are the same, for a lot less money too. I have the 9500, it looks great, but I can get the same cooling with the amd heatsink with a fan at 30db.
The idea of that post above was to point out that the ability to cool is not especially impressive if you mod a stock cooler.
The heat from the 1900 cards needs to exit the case fast, I have 2 in crossfire, the stock solution pushes the air out of the vents at the back of the case, with this new zalman that air would be circulating round the inside of my case, so I doubt the overall system temps would benefit.
There may be situations where they could work, but for the money you could do it yourself cheaper, if you are inclined.
Exactly, can't see it doing anything special. I doubt it will be sufficient for X1900/X1800 and 7900.Quote:

Well im kind of upset now that I bought the FS-V7. I only did because this was supposed to come out late Q2 of 06. Oh well I doubt it will even be much cooler but i will probably make the switch any way.
Well i bet that the VF900-Cu will be better than the VF700-Cu. If it is not better, than Zalman would be really dumb to introduce another cooler with nothing better than the older model. They already tested it and generated some improvement and than decided to mass produce it, so don't worry, it will be better than the VF700-Cu (which i got 2 days ago, i love it). :)
Well from my view I think Zalman has done the correct improvements over the 700:
1) Heatpipes.
2) Low-profile.
3) More silent on 12V vs VF700. 25dB vs 28.5dB which is a better max noise lvl imo due to their "Quiet Computing Solutions" motto. At least I thought the 12V was slightly too loud so I bought a fanmate 2 for my VF700.
4) Lighter
On a swedish site I see the price shown as 31€ ($37).
I would bet this one will do about 3 - 4C better load temps and those other improvements are enough for me to wanting one whatever it performs better or not. ;)
I keep reading this over and over on various places. Some people even thinks it's a single slot cooler.Quote:

VF900 - Dimensions : 96(L) X 96(W) X 30(H)mm
Well of course, lower speed, less noise. Surprised? My guess is that the numbers are measured with the included FanMate connected, which maxes out at 11 V IIRC.Quote:

Still no reviews? :(
yes, I want a review of this gpu cooler!Quote:

Great find
First post updated
How lame, a brand new supposedly beefy cooler like this and it gets tested on a 6800GT? Give me a break. It mentions at the beginning of the article how most coolers can't cool an X1900 these days bringing me hope that it was going to be tested on that but no, the 6800GT is used instead.
92 mm fan?
Contact area looks huge to me...
I'll have to see if my 6800 fits...
lol. they type like 4 pages of stuff we already know and then come with one test diagram. Ewww it's better, well :doh: If there isn't even a 10 degrees difference from a stock cooler, then compared to an x1900 with it's beefy heatsink, I'd say it would still top at 80 degrees.
But we'll see.
I vow that when I am finally able to review desktop computer hardware, I won't be writing sloppy cr@p as this.

on a 7800GT, better than a 6800GT as we've seen.
Seems like the best air-cooling solution right now.

I ordered one, anyone else want to take a chance? (showing 4 in stock) specs are right.. pic is not.. so I'm hoping
Edit: Shows 19 in stock now!
Just ordered mine too mate
i wanna see a review of one on a X1900.
a 7800 is a pretty cool GPU.
and then i dont mean a X1900 with a low temp but one of them hotheads that ive read about on XS.
Looks very good. Im still displeased by the lack of a strong fan being used on these cards. Id almost prefer them go to a triple slot so that we can add our own fans.
there is.. just not a hothead. Stock cooler doesnt even report 70C, I guess temps are either way off on this card or way off on everyone else's. And 2min of atitool 3d doesn't mean anything... the temp was still rising so who knows :/Quote:

to see if this solution really is the best 3rd party cooling solution around is to test it on a hothead in a room with a high room temp.
Cause common some of the hothead X1900s ive read about had a ok room temp (stil winter in some places) so i wanna see what a hothead does to this zalman on a hot summer day.
