The CNPS9900 MAX-B combines some of the most advanced technologies in the market used for CPU coolers to create powerful cooling performance. The CPU cooler utilizes composite heatpipe which is 50% more effective in transferring heat compared to ordinary heatpipes. Combined with a whisper-quiet 135 mm blue LED PWM fan positioned between two massive nickel plated pure copper heatsinks, the CNPS9900 MAX-B is more than enough to satisfy overclockers and users who are looking for ultra powerful cooling performance in silent operation.

Looks and works well, but don't discount the size of the thing
After measuring a couple times i knew this thing would fit and it did, but this thing is huge. I'm using this on an asus z87 pro with a new 1150 socket intel. Des not impact memory slots. Make sure your case is large enough.

Buy it, just plan on a struggle to put it on.
Pros: quiet, pretty blue led, looks impressive in your rig (if you have a window to the mother board). The temps are doable, seem to be cooling the system enough under stress w/o any abrupt shut downs. It's not obstructive on a asus z87 pro motherboard for ram. (a big problem with aftermarket cpu coolers)cons: dear god zalman put out a new backplate adapter for the 1150 boards. This one was a pain to put on. I got it on, but wasn't happy the time and cussing it took me.Other thoughts: yes i'm sure others had an easier time than i did. I just feel as a first time builder that can read directions it shouldn't be that hard.
By Amanda Sippola
Great cooling, but noisy after 4 months.
Cools great. Looks great. But i don't know if i got a bad unit or if their fans are just junk. I've had it for about 6 months and most of the time its running at idle speed. The last couple months the grinding noise has been getting worse. I tested all the fans in my case, and manually ran the speed up on each one, and it is this unit that once it hits about 1500rpm the grinding noise goes away.I'd rather not replace the whole heatsink, so i'm right now looking for a replacement quality fan for it.

Awesome but..
Everything its awesome of these cooler but it was hard to adjust it to the motherboard because the screw at the beggining appeared to not be long enought but fit good.
By Antonio Barrett
Cool but difficult
It looks great it really does. And it is fantastic at keeping your cpu cool. However the installation for this piece is very difficult. There is next to no room to maneuver when trying to place the screws which gets very old very fast.
By Emma Gray
You're screwed if you have amd fm2/fm2+
The backplate and the provided 3mm screws dont even come close. The provided amd clip is not even bent as shown in the pics!!! Wtf zalman???!?!?Its a nightmare trying to install this fan!!!
By Danile Da Costa
Do not buy for am3+ socket (fx-series processors)
First, this thing looks amazing, and probably works great, but it is not designed for am3+ processors, even though it's printed right in the install manual. There is no way to make the included brackets work without bending them, or really forcing the board toward the mounting bracket. On top of that, mine was missing screws, and the fan was actually bent between the two sets of fins. It's disappointing to see such great design fall so short when it comes to actually installing and using this thing. Will be returning and buying a noctua instead.

Keeps system cool
Works better than the bulky cool master i had. Not to mention it is quieter. Orb design looks nice, i like the blue leds, and it affords better access to the ram slots. All of this, for about the same price as any decent name brand air cooled cpu fan. I am running i7 with a nvidia 660 ti gpu. I am not overclocking much, but i do play high demand games and this keeps everything under 50*c.
Not good for overclocking the i7-3770k
Not at all as good as it's ratings suggest. When over clocking the i7 3770k you need something better for good temp. Control.
My second zalman cooler of this model
They are great coolers and look nice to. This is my second i had to replace my first cause the bearing was starting to get noisy and the fan was starting to slow way down. That old cooler ran for 3 years straight 24 hours a day. So if this one lasts that long i will be very happy. It keep my i5-2500k overclocked nice and cool!!
