New Zalman cooler. CNPS 8000A with heatpipes

Post by Webfire » Thu Mar 10, 2005 11:57 pm

Zalman showed a new cooler at Cebit 05.

(German page, but with picture)
Looks quite interesting but also very heavy, the poor mainboards.

The fan inside can be turned in the direction you want. That's definately a good idea.

Wow! Seven heatpipes! Dunno if I need it but it's impressive anyway.

Yeah! But it looks like the actual fan is attached to the holder with two screws just like the older models. If so then it's all depending on how the lid on top is attached...

Looking at pic from the link above, my first reaction is the fan doesn't look very secure and may create vibration just because how it's attached to HS.

Just my 2 cent. :wink:

wouldn't it be cool if the fan slowly turned around on the vertical axis?

Apparently this design was created after R&D got some wicker chairs for the office.

I wonder if there will be an aluminum version...seems silly to take twice the weight for maybe a 5% performance increase. That thing looks like it could weigh a kilo...

On the first page there is an aluminium version shown, well at least it looks like one.

yeah, still with the copper heatpipes though; that's a lot of torque.

I wonder if this design would benefit from a radial blower (like on the coolermaster aero series) instead of a normal fan. Granted, you'd have to take off the top for intake.

is it just me, or does the fan's position seem less than efficient?? i mean, it's really the only orientation you can use given the shape of the thing...but, i dunno...just seems like it would generate a lot of turbulent airflow in a few directions..

At first I thought the whole thing was made of heatpipes.

It looks to me like the copper version in the big pic has more closely packed fins, although the one in the smaller pic looks as spaced as the aluminum one.

My first thought was that this cooler would be great with NO fan. If you could put a hole in the lid, it's just begging for an intake duct.

what about this thing? Is all this heatpipe hype just getting a bit too.... hypish?
found at http://www.hexus.net/content/reviews/re ... 9JRD0xMDM1 alongside the new Zalman fanless case mini review.
I mean a heatpipe is suppossed to carry heat from a hot place to a cooler place. In this ring set-up, the fins are already likely to be the same temp wherever the heatpipe would be connected in the first place,

Until I see an SPCR formal review, I'm gonna have to call bullshit on Zalman.

wooglin: yeah that looks like real BS.

Edit:...and now I saw the second heatpipe, sorry about that, it wasn't obvious to me. Ok, maybe not BS after all, although I don't think that the 7x00 series is optimal for adding heatpipes to..
and yes, I'm drunk... just had another shot of Hallands fläder, not my favo(u)rite but still quite ok compared to O.P. Andersson or Gammel Dansk (sorry schronix and other fellas in DK but it really stinks) 8) Review comin' up soon somewhere.-

About the 8000: someone please rip the lid off, pull out fan + holder, and mount a nexus 92 on top of it (yeah, with a duct from the side of the case).

With their recent fatal1ty and LED editions in the 7000 series and now this 7700HP model it looks like Zalman wants a part of the market that is normally served by Thermaltake and other Bling oriented brands. Probably because there are more buyers in that market than in the silence market.

Now if they invest their extra revenue in research, we might actually see the NEPS and other quiet products come out.

Someone correct me if I'm wrong, but if the heatpipes carry the heat to the heat dissipators, i.e. the thin fins with high surface area, then this looks like a really nice design.

The heatpipe is to carry heat generally from the source, to the place where it will be dissipated the easiest. On this sink, the temperature at the top edge of any given fin will be the same as the temp at any other fin, so the heatpipe is doing nothing. (the Zalman 7x00HP we're talking about)

Looking at it a little more closely, what are the chances that the 1/4inch think plate down the center of the HS is carrying more heat to the heatpipe? If that thick 'fin' is actually a heatpipe itself, then maybe we're talking something new. If it's just an extra thick rib of copper, then I stand by my original comments.

Well, I am assuming that the heatpipe is connected to the base of the heatsink. It isn't visible in this photo, though, but we really can't see it very well. I can't believe that a top-notch HS manufacturer like Zalman would have heatpipes that connect only to the fins!

Maybe you can't, but I can fairly easilly see the heatpipe is not connected to anything else than the tops of all the thin fins and the one fat fin. This is a heatpipe we are talking about, not a vapor chamber. You can see the whole heatpipe from end to end.

They've done more changes.
Edit:(The original have 65 fins, )[yeah that's the 7000, stupid] this one have 72 + big fat one (which is not 1/4", but closer to 1/8" :wink: ), so the fins must be thinner. The big fin crosses the center of the CPU and because of the sharp edges it looks like a piece of machined copper,
not a heatpipe (I hope I'm wrong!). I really don't know how good/efficient this part will be in transporting heat up to the heatpipes,
and I don't feel like doing a thermal analysis in Ansys right now. :P


(..oops, got a brilliant idea, better write it down before I fall asleep!)

Hehe, Fatal1ty edition 7000 and vf700 :roll: http://home.htp-tel.de/wknappe/cebit/DSCN0164.JPG

And here is a blue version of the pointless(?) heatpipe thingie.. You can see the bottom. http://home.htp-tel.de/wknappe/cebit/DSCN0166.JPG

I'll admit that the blue on has great bling factor.

I must say that I really like those colors! But I won't have window + lights, or keep the case open, so it doesn't matter....

looks like that fat copper fin is just to hold the heatpipe in place securely (the thinner fins are kinda flimsy)
agree with wooglin abt 'heatpipe hype' :roll: this is so stupid

recall the zalman HD cooler has similarly dumb use of heatpipes, they have a (large) source sink at the heatpipe base but absolutely no 'target' sink for the liquid to condense at

Also don't forget the reports that in the early model HD coolers the heatpipes didn't even really conducted past the bend. That makes a bad idea badly implemented :roll:
