Zalman CNPS9900 MAX CPU Cooler Review

If it wasn't just because of the CNPS10X Extreme CPU Cooler, I'd say Zalman definitively bets to produce coolers based on their unique design. I can really argue on how full tower coolers can be better for extreme overclockers or people who just want to push their hardware to the limits in non-extreme conditions. So let me start this review going 2 weeks back in time when I received the Zalman CNPS9900 MAX. Of course I was thinking this could be a good cooler, but I really couldn't think on how it could compete in the major leagues. Some days after that, we received a "reviewer's guide", with detailed features and comparisons about this new product. I started reading it when I got surprised; there was a chart comparing the CNPS9900 MAX against the Thermalright Venomous X full-tower cooler and the CNPS10X too, and the CNPS9900 MAX was showing the best performance among the competition. Of course, being this from the manufacturer, I needed to take it with a grain of salt, but I was just ready to try and obtain similar results, or simply explain how sad reality is in this article. Additionally, the Venomous X was tested with an ADDA AD1212HF-A7BGL fan spinning at 2,200rpm and moving 85CFM.

OK, so that's how I got really interested on testing the Zalman CNPS9900 MAX, as Zalman had some very convincing features including 3 heat-pipes being equivalent to 6 (U-shaped) heat-pipes, a 135mm fan, and a very appealing black-pearl nickel plating including a mirror-finished base. Also, Zalman is launching a new heat-pipe design which is supposed to be 50% more effective in heat transfer compared to ordinary heat-pipes. Through my review, I'll test the CNPS9900 MAX against the very popular Prolimatech Megashadow, and a pair of dual-tower heatsinks: the Cogage Arrow (pretty much the same as the new TR Silver Arrow) and the Noctua NH-D14. Before starting, let me get things straight. Don't expect tons of charts with different fans as the CNPS9900 doesn't have the ability to change its fan. However, keep in mind this CPU heatsink utilizes a 135mm fan (while other normally support 120mm fans) and it's said to work at 1500 and 1700 rpm as shown in the specifications below. You can't install a second fan either, but I'll test with 2 different CFM configurations; one quiet and another one not very quiet, but enough to move similar CFM as the fan shipped with the CNPS9900 MAX. For more detailed information about our testing methodology please read the next pages.

Interesting offering. At least Zalman is trying things instead of sitting back. I haven't seen anything really revolutionary since the Cogage True Spirit, and then only in price to performance ratio.

I still think the Cooler Master v10 got a bad rap since reviewers were unwilling to match it to its performance level--which is 80C or higher temps when OCing Core i7s. The v10 is just another cooler until you turn on it's Peltier system.

Then again, if you want to keep your box relatively cool with moderate OCing, the V10 is overkill, and you'd be better going cheaper for the same performance at lower temps.

I'm glad that in the conclusion it was restated that during the installation other components were left in place adding to less than ideal clearance of the wrench. If I had to guess I'd say that Zalman, and most other manufacturers, are figuring that those purchasing a cooler are doing so for a new build and wouldn't be installing the cooler into an already built system. I'd further be willing to guess they also aren't planning on folk swapping out coolers for benchmark tests. With that said, I wouldn't count the mounting system as a con, but more as a "be aware" type of note. Up until my current Xigmatech, I've been using Zalman CPU coolers for a very long time and I look forward to a time when they combine their composite technology with HDT all in the Omega layout. Good stuff BMR, keep up the good work.

You're probably right about building a new system, but as I've said, even in those conditions installing the CPU cooler with the wrench takes more time than with a screw-driver. Also, you've got 3 tapes for installing it, no more.
And the reason I considered it like a con, is because nowadays many PC cases come with a back-door for CPU installation without removing the motherboard, and doing it gets really difficult, especially without removing your RAM and PCI-e cards.
Thanks for the heads up.

No worries, I was looking at it from a new build perspective versus a benchmarking/testing perspective where it's one and done for the install. A "backdoor for CPU installation" meaning a slide out motherboard tray (like the Lian Li PC65B my favorite and current case)? Or something more dedicated to just a CPU swap? Sorry, didn't mean to half-hijack the purpose of the thread/review here in comments :)

Sorry, I meant "CPU-Cooler Backplate Installation", not CPU installation. This way I'm referring to a hole in the motherboard's tray so that you can install CPU cooler's backplates without removing the motherboard. Many PC cases have it nowadays, including the Obsidian 700D used in my review.

FWIW, you can't always install two fans on some coolers that allegedly accept them. For example, I'm running a Megahalems on my ASUS Rampage III Extreme mobo, and it's so close to the RAM sockets that if you install RAM in the socket nearest the cooler, a standard 25mm thick fan will not fit. A 12mm "slim" fan will, but Prolimatech's included fan clips only work with 25mm fans. This forces me to run a single fan on the rear of the cooler.

Use thin copper wire and push it through the top and bottom fins, and through the fan holes. Use a strip of the silicon that comes with fans to deaden any vibration sound. I hated the mounting wires on my Cogage True Spirit that I literally ripped them off in frustration and used copper wire to attache it to the tower. It's a tighter fit too.

I'm shying away from the Mega and Ven-X because I'll be running at stock for most of the time so the super-coolers are a bit overkill, but when I do clock up for rendering and encoding, I'll be running 65+ CPU load at 4.2GHz

So, the direct question: running over 4GHz on 980X for a few hours - yes or no to this cooler?

Will you be using standard voltage, or adding voltage with overclock? If you keep the standard voltage, this cooler is more than enough to tame temperatures. Still, I think the Scythe Mugen 2 offers the very best bang for the buck.

Undervolting as far as possible at stock (estimating 1.1v), and if my past few i7 920s and 930s are anything to go by the 4.2GHz OC shouldn't need for than 1.27v on Extreme Edition silicon, but I reckon 1.3v upper limit is realistic.

Since your CPUs don't use high voltages fores the frequency desired, this cooler should be enough. I would skip this and get a dual-tower cooler for your CPU if you're planning to going above 1.4 volts.

If you're going for the 4Ghz OC you will need a better cooler for any type of sustained computing. Just get the Cooler Master V10, install it, and call it a done deal. It's there when you need it.

I have an ASUS P8P67 PRO, and it has a huge plate on the back of the motherboard to hold the CPU. Will this cause a problem when mounting this cooler?
I am thinking of buying it, and need an answer to this.

Thanks

You shouldn't have a problem. Why do you say the P8P67 Pro has a huge back plate? All 1155 socket motherboards have it like that.

Oh, do they? I didn't know. I just upgraded from a 755 which does not have anything on the back/under the CPU spot.

On the Zalman website there is no mention of tape. Nore is tape displayed in the "How to Install" demo video.

And I downloaded the manual, and no tape was shown.

I guess they have improved the model since this review.

Open this: ##zalman.com/ENG/product/Product_Setup.asp?Idx=416
In the second step where they're preparing the heatsink backplate they put an squared sticky tape (color=yellow).

I contacted Zalman support about the stickers, and this is what they said:

Thank you for using our product.



The Double-Sided Tape is for user convenience only. It helps the Loading Block assembled Backplate to be attached to be backside of motherboard while installing the cooler. If you do not use it, you will just be burdensome while screwing in the bolts due to lack of it.



If you need such kind for easy installation, you may make it with commonly used electrically non-conductive double-sided tape by yourself.



Regards,

Tech Support/ZALMAN

So it's not really a necessity. Getting mad a Zalman as you did in the review was clearly not valid.

Anyways, I just put in my order.

Oh, and by the way. My Noctua 755 cpu cooler also had this sticker thing. As do many others.

You'll need it if you're installing it inside a PC case, but if you get another pair of hands to help then you're already at the other side of the fence. I guess that's good news.

a week later i realized i had used to much zalman grease, so i pulled it cleaned ,one small pea and put it right back in .
No Problems what so ever , easy very easy !

so how can i do this with no experience, yet the rest whine about it ????????? oh it works great!
