For the PC-enthusiast who wants a desktop that looks sizzling hot, yet stays remarkably cool, check out the Zalman CNP9500 AT CPU Cooler featuring a fan and heatsink! This hi-tech cooling device lends a rich, bright look to your PC with its flashy heatsink and frame, durably crafted out of pure copper.

The heatsink saves space with an architecturally sound 3-pipe system that effortlessly whisks heat away with the help of the automatic fan’s 92mm blades and 2 ball bearings. Controlling the fan is a PWM chip, which automatically adjusts the fan’s speed based on CPU temperature. It operates at a stealthy 18.0 dB at 1300 RPM and quietly revs to 27.5 dB at 2650 RPM during heated PC action.

  • newegg PWM Control Fan A low-noise 92mm PWM Control fan automatically controls fan speeds ranging from 1,300rpm to 2650rpm for silent cooling in relation to CPU temperatures.
  • newegg Unique Heatpipe Design Three innovative and curved heatpipes provide a heat capacity matching up to six heatpipes for maximized heat transfer.
  • newegg Optimized Heatsink Layout and Ultra-Slim Fins A 100% copper heatsink with an aerodynamically optimized "tunnel" design and 0.2mm ultra-slim fins maximize heatsink efficiency with minimal weight and smoother airflow for optimum cooling.
  • newegg Intel Platform Compatible Compatible with the Intel LGA 775/1155/1156 platforms, the Zalman CNPS9500 AT provides an ideal cooling solution for Intel Pentium 4, Celeron D, Pentium D, Core 2 Duo, Core 2 Quad, Core 2 Extreme, and Core i7, Core i5, Core i3 processors.

2018 Clip design out of the socket 7 era, and among the worst clip designs ever.

Pros: It cools better then the stock intel cooler once\if you get it installed, but it doesn't cool anything amazing for a supposed 6-pipe cooler, but noway am I taking this thing off after what I went through to get it installed.
See below.

Cons: Worst clip design ever, requires a stupid amount of pressure because they made the screws\bolts the clip needs to screw down with about 25% to short when installing the clip as the clip is a seasaw like a socket7\370\A clip. They pop out due to not being able to get enuff thread, you don't have 3 hands to push the clip down while screwing in so this constantly repeats all while your getting cut by the INSANELY sharp fins, that should of been rounded... I think I cut myself 6 times on this thing.
Finally I got it installed but it REQUIRED me getting a 2nd person to HOLD the clip down with as much force as possible, and it still was barely possible, but we finally got the screw past the first thread to hold.
Hopefully I never have to take this thing off ever again.

OH did I mention the fin edges are SUPERSHARP and not rounded, keep cables far away from this thing, but good luck keeping your hands away from them while installing the clip, that is gonna rebound and cause you to get cut.

Other Thoughts: Can only give this 1 star due to HOW terrible the clip is. Reviews you find online of this sink are of its original 775 version, which seemed to have a more forgiving bendable clip and longer bolts, they weren't trying to save less then a penny on, unlike this more modern version.

Don't buy this even on sale.... I totally regret buying this just cause it was on sale, I should of got one of the hyper 212's with the great designed spread clip that wouldn't of resulted in my hand having a bunch cuts, and that is really the main reason it gets 1 eggstar.

It's 2018 I shouldn't be getting cutup by a heatsink, there is no good excuse for not rounding the edges of the fins and DEF no excuse for the SHORT screws that would of prevented this negative review as that clip and the short screws were the direct cause of me getting cutup by those sharp edged fins.

Needs 1 additional longer screw for the mounting bracket. Keeps the CPU nice and chilled.

Pros: Can't go wrong with copper.... that is unless you can't get the mounting bracket to hold down the heatsink.

Cons: The screws are too short to mount the metal bracket into the plastic housing.
No matter how much pressure you apply to the bracket, the screw will not catch the nut inside the plastic.
I'm going to see if I can find some longer screws at Lowe's or Home Depot in the morning. I fiddled with this thing for over an hour only to lose the battle.

EDIT: After going to Home Depot, I found a screw that was the same machine thread and a bit longer. The screw worked perfectly. The heat-sink mounted nice and snugly. My Intel i9 9900k averages 29-35 degrees C when idle and 52-60 degrees C when playing Battlefield V on max ULTRA settings 1080p.

Other Thoughts: I've increased my rating from 2 eggs to 4 eggs. I just can't give 5 eggs because of the short screw issue.

Incredibly disappointed

Pros: The copper fins and CFM

Cons: The bracket and/or screws/hardware. Very poor quality, I could not keep the cooler bracketed onto it. I had to run out and pickup a different CPU cooler because of it. Really incredibly disappointing, this fan was a nostalgic trip back to one of my first big PC builds with an aftermarket fan and I would have loved to have it. I will be returning it.

Very effective but difficult to work with and delicate

Pros: Good heat transfer, fits around most MB architecture. Cheap, solid copper

Cons: finicky mounting, Fins are sharp and delicate. wiring for fan is ugly and gets pulled into the fan with no good place to secure it. Even when fully mounted the Heatsink can be moved or twisted.

Other Thoughts: I might use this as a passive cooler the mounting system needs some thought.

Quiet. Seems to work really well.

Pros: Quiet
Easy to install
Comes with thermal paste
Reasonable price

Cons: Installation instructions could be more explicit (see writeup)

Other Thoughts: I bought this for my 2nd build (1st was maybe 8 years ago, so it's been awhile). I went with an i5-8600K. The mounting cage installed easily. My only concern was the bracket across the middle that actually holds the fan in place on the cpu - it seems like it puts an awful lot of force on the cpu. I even double checked the installation instructions - the only thing it has is a fairly small picture of the bracket orientation.

I went with an ASUS Prime Z370-A mobo which allows for plenty of room between the cpu fan exhaust and the top rear case fan (maybe 1.5" or so).

Just installed

Pros: Installed this a few minutes ago on a 1150 socket and seems to be working great.

Cons: The clip that fixes the heatsink/fan in place was difficult to clamp down with the screw provided. Apparently the screw was too long for my mobo - there was a motherboard part right under the clip support that prevented the screw from screwing in.

Luckily I had a computer screw kit nearby - and I tried a shorter screw. Amazingly it worked! The clip is now properly locked in place and my pc is ready to rock and roll.

Other Thoughts: If you buy this be sure to have a few extra screws handy - they could save your life.
