ZALMAN CNPS10X Extreme 120mm CPU Cooler with Worlds first PWM Fan Speed Controller

Pros: Does its job
Seems sturdy
Looks decent

Cons: Scroll wheel could be faster
Kinda small but you get used to it

Pros: So far it's cooling great, I went from average temps of 38C down to 29C at Idle, using the lowest fan setting which rotates at ~1000rpm. You can not hear it! At higher speeds it's definitely audible but not crazy loud, this is a 120mm fan so you won't get that high pitched whine like a Stock Cooler.
The ability to mount the controller outside the case is very nice, you probably get about 12" of cable, so don't expect to mount this much beyond the case itself.
Install was fairly easy on a AMD Processor. I probably didn't need to take the fan off, but did anyway and that proved to be rather cumbersome to get back on once mounted.

Cons: This thing is HUGE, that may not be a con to some people.

I can see if you are using this on an Intel Chip, it would take more time to install.

I don't feel that the AMD clip is very tight, but it's holding fine for now.

Controller extension cable can easily be detached, it should have a securing clip of some sort.

Other Thoughts: Motherboard: ASRock 990FX Extreme3
CPU: Athlon II X4 640 (3.0ghz) not OCed
Memory: Corsair 2 x 4 GB XS3 1600
HD: WD Raptor
Video: PNY nVidia GTS250
PSU: Corsair 650TX Enthusiast

I had no fitment issues, with this setup, granted the Fan Power Plugs were a little hard to get to after mounting.

If my memory was any taller this would not work, the XS3 does not have a Heat Sink that sticks up so it worked fine, but I only have about 4mm of clearance on the A1 Memory Slot. I installed the Memory before mounting this thing, it would be difficult to change it out in the future however.

If your impatient you probably don't want this, it will require a ton of patients to install proper.

Pros: Cools great.

Cons: 1) Large
2) The bracket was tricky to get on and it's un-coupled twice in the 3 years I've had it, but I guess in 3 years and only twice, that's decent right?

Other Thoughts: I didn't realize how big this thing was. Seeing the dimensions and seeing it in my case were two different things. My computer runs a little hot still...but it's due more to the space restrictions in my tower and airflow.

Pros: Core i7 920 2.66GHz - OC Testing
Stock @ 3.2GHz: 80C
ZALMAN @ 3.2GHz: 38C

ZALMAN @ 3.9GHz: 53C

A huge decrease in temperatures. All temperatures tested using the lowest (blue) speed. Very quiet at the lowest speed, slightly audible at the highest (red).

Cons: Difficult to install. When first installed, i wasn't lined up flat with the bracket, and had to uninstall and fix. (Caught before boot).

A little large on height. While it didn't block any RAM slots, it did require I remove a side fan on my case door in order to close it.

Other Thoughts: Looking forward to using this again after upgrading to an Ivy Bridge processor.

Pros: I'm sure this is a greak CPU fan for the boards it actually works on. Looks amazing - really disappointed I won't be able to use it.

Cons: While the brackets and screws fit fine into my brand new X79 Sabertooth board, the tabs that hold the fan down ended up being about 1/8" too high. This allowed the fan to float around and tip off the CPU. Despite both newegg and the Zalman website assuring that this fan is compatible with LGA 2011, the box and the instructions don't mention it at all. Furthermore, the instructions available at the Zalman website tell you to use special Intel brackets that aren't even included in the package!

Other Thoughts: Are you supposed to order special brackets separately for LGA 2011? If so, PLEASE state so before I purchase.

I waited 3 weeks for my new 3930k, and now I'm going to have to wait again for this fan to RMA while my new one is shipped.

Hopefully the next company I buy from (which I can assure you WILL NOT be Zalman) won't lie about compatibilities to sell a couple extra fans to suckers like me.

Pros: Big fan, big heatsink, very good mounting kit, good cooling.

Cons: I finally got to install this after going through a long process of picking parts. I got it installed, up and running. After the boot process settled down I reached over to turn the fan speed adjustment and POP! Yellow sparks shot out of the control unit and the CPU cooling fan went to top speed. Now my super large (NZXT phantom) super quiet case has a loud spot. I'm not happy I might have to fully disassemble this full build.

Other Thoughts: I tried to figure out on Zalman's site how to get this fixed, but alas, I can't find anything beyond ads for their product and manual downloads. I don't know if any of you other newegg fans know how to contact this company, or if Newegg can help. All I need is the little controller piece and I should be set.

Pros: Keeps my i5 processor nice and chill!!

Cons: This Thing Is HUGE!!!!

1) Unable to use all my RAM slots due to their heatsinks hitting the fan on the cooler

Other Thoughts: Make sure it will not interfere with anything. had to modify my side panel fan so it wouldn't keep hitting it.

Pros: My first Western Digital VelociRaptor and i love it. Its fast and reliable so far.

Cons: None so far

Other Thoughts: Kinda noisy when on load

Pros: Adjustable Fan Speed, Excellent Cooling Performance, and Universal Socket Compatibility.

Cons: It was kinda big

Other Thoughts: Had to switch the heatsink the otherway because it was blocking one of my ram slot.

Pros: Runs quiet, keeps the CPU very cool. 10 degrees cooler than stock at half the RPMs ...

Cons: I got the REV 1 cooler and the only attachment for my AMD 1100T was the weak spring clip. My computer would blue screen every time something bumped the case, which told me that the cooler was too heavy for the clip. As the clip weakened over time, the slightest touch would blue screen the machine. When I went to replace it with the stock cooler, it's size made it so difficult to remove that it twisted in such a way as to bend hundreds of pins and destroy my 1100T. So not only was this a waste of money, but I lost my 1100T and the only chip I could find locally was the 1055T, a severe downgrade. Thanks a lot Zalman and Newegg. Note: I got mine on sale, which meant that the REV 3 was already out and it has the screw on pressure plate to hold the cooler securely. Neither Zalman nor Newegg warned me that I was getting a cooler that was known not to work with the AM3 socket. Shame on both of them. It also interferes with tall memory like the vengeance.

Other Thoughts: It you get the REV 3, then this is an excellent cooler, assuming it actually fits your case. Watch out for tall memory ... if the slots are close to the CPU you will have problems with this cooler. REV 1 should be avoided by AMD users.
