Zalman CNPS7000CU

[singularity2006]

it looks very promising.... but I've never used it. All i know is that it's unusually expensive. I'm just very reluctant at the moment to get that heat sink cuz i just recently got my Vantec Aerofan which uses tip magnetic driving instead of a ball bearing.... most quiet fan I ever have used... the only noise is the airflow... u can't hear the fan itself.

Anyhow, I'd hold off until the price of that particular zalman drops to about half price, which won't take very long.

Quick search on Google and there you go :)

They also have A/Cu (aluminium/copper) version. It should be much lighter. Also don't forget that copper oxidize over time.

Looks like there's one serious problem with this fan -- its size. It won't fit on some motherboards. Here's the link: http://www.zalman.co.kr/english/news/20030224.htm

I'm getting on of these fans next week I think. So we'll see if it's really noiseless and keeps CPU cool :)

Yea, I thought of that after I posted. And I always find it annoying when others ask question without research.

The other problem that I found because I didnt properly research is that I have an AMD 2000 on an ASUS A7V333 so I dont think that I could get it to fit and even if I could it might be a little over kill. Guess I'll stick with my plan for the SLK-800 or similar. But please keep us informed on how it performs.

P.S. can someone please make a spell check for this site. I really need it.

The HSF itself from what I have read performs very well. Keep in mind that it is bigger than it looks, but the fins are designed to provide clearance for everything underneath it. Unfortunetly, it is only availiable for PIVs and Athlon64s...

I will still take my Swiftech 462 anyday. :)

[singularity2006]

yah, i was totally concerned about the size issue too. I remember the first zalman I got... the clearance for the capacitors right next to the CPU were.... close. This one... eh, no way.

I have this Heatsink/fan mounted on a p4 2.8c and it works great. It is really quiet and performs really well to. My temps never seem to go over 35 degres. I had no problem mounting it on my gigabyte motherboard (Gigabyte GA-8IPE1000 Pro).

[GregHess]

Its currently the #1 heatsink on the market currently for Noise/performance levels (its extremely quiet for its performance) for Pentium IV/Athlon64 applications.

As for copper oxidation problems...this has been proven not to be a factor in cooling performance. In fact some sinks which haven't been treated, will actually arrive with some oxidation having taken place.

By the time the oxidation reaches a level thats noticable (in most treated heatsinks), you'd have most likely replaced the entire computer.

Here's some more indepth reviews...the frostytech has a soundclip.

The alu/cu blend would be good for slower p4's, with the copper one for the 2.8+ P4's.

(Btw overclockers.com is a VERY reputable site. )

Frosty's awesome with heatsinks.

As already mentioned, be careful about size issues. It is also possible to use this heatsink with Socket A solutions...but requires modification to do so. (It won't work out of the box).

[AmbientLight]

Thanks, Greg. I think I'll give a copper FHS a try, since I'm planning to install it on top of P4 3.0C.

I better make sure I don't drop that baby on to my foot. 773g! I might end up in the hospital :) The weight is also an issue with this heatsinks I believe. It is well over what Intel recommends. Initially I wanted to try acu/cu because it falls under Intel's recommendations.

[GregHess]

Hey Ambient,

Either of the two combinations would be fine (both are realtively close in performance) but I myself would err on the side of the copper sink, due to the low fan rpm involved here.

Up to you though. If your buying from a local shop, you might be able to return the alum/cu version if your not happy with it.

[singularity2006]

I'm still pretty surprised there haven't been many if any reviews of the Vantec Aerofan... any thoughts about that particular HSF compared to this one?

[GregHess]

Its louder and less efficent.

Costs alot less though.

Frostytech has a review, and I believe so does overclockers.com.

[singularity2006]

the aerofan is louder compared to the new zalman?? no way! hah, this is like the best HSF I've ever used in my life! The only noise I hear is the sound of the air flow... no bearing noise.... love it... works soooo well.

[GregHess]

Ya its actually louder :).

The Zalman 7000-cu is currently the top ranked performance/noise heatsink on the market.

In low rpm mode, your hd's will be louder (even if their fluid bearing IDE drives).

At least, according to most reviews. Haven't built a P4 with one first hand yet.

[AmbientLight]

I'll post results here and we'll see first hand if it's any good :) Fortunately, I'm not sponsored by any hardware manufacturer, therefore I'm not biased.... ummm.. maybe a little :D

[singularity2006]

wow... interesting... that thing must be next to silent then... and it's using a ball bearing too? geez.... aight, let's see some reviews. =D But yeah... the cost of it is holding me back still.... =T

[GregHess]

Reviews of what? The Coolermaster Aero?

http://www.frostytech.com/articleview.cfm?articleID=1393

According to frosty at its quietest setting....

The Coolermaster puts out a mere 38.6 db.

But at its loudest setting, it smacks down with a WHOPPING 62.7 db.

The Zalman by comparison puts out 41.7 db...but also manages to run cooler then the the Coolermaster.

[singularity2006]

oh no no no Greg. I'm talking about the Vantec Aeromaster, not the Coolermaster. The Vantec Aeromaster can be found here:

http://www.vantecusa.com/afc250.html <--- not quite a direct link... their site uses frames and such, a lil hard to pinpoint. But they call it the "Aeroflow" now instead of the "Aeromaster" .. I'm guessing to clear up the confusion between Cooler Master's product and their's. My original box says Aeromaster. =)

Yah, I'm quite aware of the noise issue w/ Cooler Master's thinger.... but this is a totally diff product.

[GregHess]

Oh that guy!

I actually have one of those things. Its loud as HELL!

I replaced the fan with a Panflo L1A cause I couldn't stand the noise.

Of course the TMD's aren't as loud as some fans on the market...but damn man...they're still really noticable.

I actually have that TMD just laying around now =/.

Zalman CNPS7000CU (http://www.sharkacorp.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=SOS&Product_Code=cnps7000cu&Category_Code=cpu-cool)

I use Zalman CNPS5700D-CU (http://www.sharkacorp.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=SOS&Product_Code=cnps5700d-cu&Category_Code=sock478) with iP2.4 in silent mode and I am satisfied, it is not noiseless but very very quiet. (in silent mode), with Enermax powersupply that is very quiet too.

[singularity2006]

wow, now way! I mean, if we both have the same type and same functioning fan and u think it's loud as heck, it makes me wonder what ur definitions of "loud" and "quiet" are... -.-" I actually can't hear the fan at all in my system. The only thing I hear is the flow of air. =D I love this sux0r... hehehee.

Singularity,

Remember there are two variants of the 70mm TMD fan. One is a low rpm, and one is a high rpm.

I think I might have the high rpm one. You on the other hand might have the lower rpm model.

That would explain our differences in noise perception.

[Ckerr812]

You want loud, try the Vantec Tornado! ;) I put two of these in one of my computers at home with Ventec Nexus fan controller, if I turn them both up full blast, it sounds louder then a vacum cleaner!

Luckly I have a fan controller on there, and they are only on full blast if the temp gets above 40 C in my system or cpu....which it rarely does.

[singularity2006]

yah, that would make sense.... but how much faster can that thing get past 5500RPM? I was assuming what I had was the higher RPM model.
