Typo police here ... second page:

"The fins themselves are flexible as they are made of fairly then copper sheets."

And also, it does not require you to remove brackets on P4 Systems... you just place the 2 aluminum bars, to the p4 bracket, and screw the fan to those aluminum bars.

well since we are doing typo police, on the last page, near the end it says: "CNPS 700CU" which I'm pretty sure was not the intention;).

BEST HSF I EVER PURCHASED!!!!!!

Best. Period. My 80mm case fans are louder than this thing. My A64 3000+ is OC'd to 2.2Ghz and running at 47C.

I can understand why you had some reservations about design, but for a heatsink with that much weight, I think personally that I would feel awkward using a clip to mount it. It needs to be mounted through holes in the board using screws IMO, and I don't consider that a drawback myself. It's more secure, and I personally don't want to mount 700g of copper over my CPU unless it's locked down to the mobo with screws so I know it isn't going to rock when I stand the case up or need to move it.

Also, at 3.5dB above ambient on it's highest setting, I find it hard to consider the internal fan controller a drawback. More like a superfluous addition to the packaging IMO. Like I said, a pair of 80mm fans on the back of the box are louder than the CNPS-7000cu. Again, subject to opinion, and you do give it a good score, but I do think that complaining about a fan speed controller that moves you from ambient noise to 3.5dB above it is nitpicking.

Just my 2c.

thanks for pointing that out. i have it corrected.

same to typo cop Gxcad

Glad to like the CNPS Noubourne. I dont know if you are familiar with the Gigabyte 3DCooler but the mounting mechanism on it is very slick and the copper version of it is just as heavy as the CNPS. Like I said, bracket removal is not a huge deal just a bit of extra work.

It is true that the CNPS at the high setting is only slightly above ambient noise but the lab here is on the noisier side with a ventilation system going as well as traffic passing outside. That said the CNPS will likely be barely audible inside a case. Some people are just more fanatical than others about that so the option of being able make the fan more or less completely silent is a bonus. Still if Zalman puts forth the effort into making a rheostat, it would be better if it was more usable. I cant see making the controller sit in a PCI slot being much more expensive than the little device they include. But like you said it is a fairly minor issue but just a little something could be improved upon in the future

Oh, you missed one more on the Conclusion... This might confuse future readers, hehehe....

The mounting method of the CNPS7000A-Cu could use some work also. It is not nearly as elegant as the Gigabyte solution as mounting requires the removal of the back plate and bracket on both the P4 and Athlon 64.

I have the Zalman and the the Gigabyte cooler, the Zalman in my main rig with a P4 3.2 running at 3.712 and at idle the CPU temp is consistently lower than the board temp, something I have never seen before, best cooler I have ever used. I didn't install the fan control so it runs at full RPM and it is still the quietest air cooler I have ever had in my main rig. As mentioned earlier in this thread with a P4 you don't need to use mounting holes and it is a super easy install.
I have the Gigabyte in my HTPC running a P4 2.4 at default speed and am not all that happy with it. Although it is very quiet on the lowest speed the noise is a low frequency that passes through the case and is quite noticeable in its home theater environment, at high speeds it is REALLY LOUD. The Gigybyte does not seem to handle heat well at low speed, once the temps get up they do not recover very fast. I also felt the Gigabyte was a royal pain to install but a lot of that could have been the fact I installed it in my Antec Overture HTPC case and there was not a lot of room to work, in fact the Zalman was originally for the HTPC but it wouldn't fit becaues the PS is so close to the edge of the motherboard by the CPU socket.
I am going to replace the Gigabyte with the Scythe Kamikaze as it has been getting raves for quiet performance in HTPC message boards.

Edit:

The Gigabyte cooler I have is the Pro, not the Ultra.

the ultra is a lot better at lower fan speeds but it still cant touch the zalman

i usually have a lot of space to work with so the installation of the 3dcooler is a breeze. it literally takes me only about two minutes to remove the 3dcooler from an athlon64 and move it to a p4 for example and that is where its strength lies imo. of course this functionality isnt as important for a lot of other people though and if they arent the type that needs to move the heatsink around i would recommend the cnps without hesitation
