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.

5 out of 5 eggsRock star cooling

Pros: Great cooling, superb design, relatively easy to install. Also has a small footprint and fits in cases/tight spots easier than others without blocking RAM slots

Cons: price without rebate? If you can afford it, go for it!

Other Thoughts: Got is cheap with rebate and am thinking Zalman may be my new 'go to' CPU cooler. Very happy with this!

Pros: -Quiet
-Convenient sizing
-Nice Color

Cons: Somewhat annoying installing "seesaw" like clamp onto my board for one of the screws ,but other than that for socket 1150 it was easy as pie.

5 out of 5 eggsGreat cooler for the buck

Pros: build quality seems solid, keeps my i5 4690K @4.5ghz ideal around 34-40*c and under load ~75*c ALSO very quiet

Cons: Clip seems kinda flimsy that holds heat sink to bracket, plus only one clip

4 out of 5 eggsLove the look, install is tricky

Pros: Large copper heatsink looks nice
Effective cooling
Quiet

Cons: Compared to the install of the standard Intel heatsink, this Zalman install was difficult. I had a retail Intel heatsink installed on my G3258 which I decided to upgrade. I removed the existing Intel heatsink and processor in about 2 minutes. I then installed my new processor in about another minute. This Zalman heatsink required an hour to install. I had to remove the motherboard, then screw the retaining clip in. I then reinstalled the processor, applied the thermal compound and wrestled with the heatsink's screws to get it secure.

My biggest mistake was reinstalling the motherboard in my case after I attached the socket clip. The case kept blocking access to the screws on this heatsink.

Other Thoughts: I have owned several Zalman heatsinks over the years. I also have a few aftermarket coolers from other brands Given what you're paying for a nice looking aftermarket heatsink, this installation should have been easier.

If you are starting a build from scratch or are willing to pull your motherboard out of the case then the install should go more smoothly. Get the processor and heatsink on your motherboard first, then install in your case.

2 out of 5 eggsNo long term support

Pros: Very quiet
Less susceptible to dust clogging than other coolers
Cools fairly well

Cons: Design isn't the most efficient
Limited socket support

Other Thoughts: When I bought this cooler, it only came with a bracket for LGA 775.
Fast forward to today, I'm upgrading and want to use this thing for LGA 1150. To make it work, I have to get a new bracket, ZM-CS5B, which is sold out everywhere except for one guy trying to auction it for $30.
After contacting Zalman direct, they want to charge $7 because the product is now "out of warranty".
However, other manufacturers have offered FREE bracket kits for this exact same situation (see CoolerMaster's Evo). So if you want long term support for future sockets, you might want to look elsewhere.

5 out of 5 eggsIm a fan of this fan.

Pros: Fairly easy to install. Runs quiet for the most part. I run a 4770K at 4.0Ghz and running Boinc projects fulltime it never gets over 70c.

Cons: I guess you could cut yourself if your not careful installing it or lose a part. The washers are very tiny but that's all I can complain about.

Other Thoughts: The Cooler Master heatsink and fan nowhere near as good as this fan.

4 out of 5 eggsGood fan, could need some more quality assurance

Pros: The little time I had it was awesome, went from a stock cooler where Overclock temps were around 60C to this, which brought the Overclock temp down to around 25C when combined with Arctic Carbon MX-2.

Cons: The fan rattled *a lot* so I removed the heat sink. Right after I removed it a screw fell out of the back of the bracket attaching the fan and motor to the heat sink. I looked through the central hole and saw that the screw mount had somehow been stripped out. this is probably a one in a million chance so I wouldn't worry about others having it too often.

5 out of 5 eggsStill Working

Pros: I have this guy in two of my systems. One for about 5 years and the other 3 years. Works great. Keeps my CPUs at good temps.

Cons: None.

1 out of 5 eggs

Pros: Shiny

Cons: DOA. Fan was dead.

Other Thoughts: Zalman is usually my preferred CPU cooling solution. Of course I realize sooner or later I was going to get a dead one.

4 out of 5 eggsexcellent heatsink fan

Pros: I have i7-4790K CPU and the CNPS9500 AT provides excellent cooling. Running at 4.0 GHz stock speed, idle temperature is generally at 20-23 degrees, and 100% cpu load on 8 threads generates no more than 58 degrees.

Cons: The installation is not the easiest compared to couple of other HSF I've used in the past (e.g. Cooler Master Evo).

You must have access to the back of the mobo in order to insert 4 of the nuts for the socket mount to be installed on from the front side.

The S clip which lies on the CPU will need to be pressed down hard in order to screw onto the socket mount (no need to be worry, it is meant to be bent-resistant). I made the mistake of screwing too hard on the S clip in order to keep it down; the plastic on mount's screw hole loosened causing the screw to pop out (happened to couple of other reviewers for this product as well). Luckily, the S clip only requires 2 screws, so I rotated the socket mount 90 degrees and securely installed it the second time.

I have also contact ZALMAN's website regarding the issue and they have sent the replacement parts immediately. Excellent customer service.

Other Thoughts: I definitely recommend this product, as it provides excellent cooling temperature and air flow. Just make sure that after installing on your mobo, it will not hinder other hardware placement (e.g. RAM slots). Luckily, this was not the case for me, but it came close to the DIMM slots.
