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 eggsAwesome

Pros: Very high build quality, low noise, great cooling, long life, super easy install on amd platforms (its just a simple spring clip)

Cons: Out performed by some of Zalman's newer designs

Other Thoughts: I would not buy this cooler again unless I had space concerns in my computer case since it is has been made obsolete by newer designs; however this is very well made. The heat sink is solid copper with a base polished to a high mirror finish. I had this thing rocking in my case for 8 years, the fan finally started acting up on me under load and had to be replaced. I replaced it with the 212 but that does not match up to Zalmans build quality. Zalman has fantastic support too, I went to reinstall this 2 years ago and broke the clip, they were able to send me a new one in a short period of time for a few bucks.

5 out of 5 eggsDoes exactly what I need it to

Pros: Very efficient.

Nice and quiet.

Installation was quick and easy.

Unique aesthetic looks.

Cons: You have to be careful when handling it on installation. I bent one of the fins ever so slightly and while no one else will see it, I know it's there.

Other Thoughts: I chose this version because my rig is black with green lighting and the only lighted fan option is blue. This is not a big deal at all for me as performance of the cooling far outweighs and aesthetics.

It's holding my i7 Core 6700k running unclocked at 35C and I'll be happy to ramp up the clocking later on from 4GHz to 4.4GHz.

This is my first Intel build following yead on AMD chips. The LG1151 socket adapter is a much better design for me and installation was very quick.

I'll be seriously considering the blue LED version for my kid's PC as it has blue LEDs in it already.

2 out of 5 eggsIt works

Pros: - Cooling performance
- Small footprint
- Unique look

Cons: - Mounting Hardware
- Sharp and thin heatsink fins

Other Thoughts: Cools a stock i5-4690k very well, but I wasn't able to get much of an overclock in before the CPU was throttling under load. However, it did perform well for an air cooler of it's size and price point.

I used this in an orange colored build and the copper fit in nicely and the shape draws attention.

I was incredibly disappointed with the mounting hardware/process with this model. I have used other Zalman coolers previously with no problems, but I had a very difficult time getting this one mounted. As a seasoned builder I had to look at the install instructions which showed installation the exact way I was trying. During install I ended up cutting my hand on the fins and bending a few in the process. They were easily bent back, but I shouldn't bleed when building a computer.

This is advertised as an "Ultra Quiet" cooler and in my opinion this is just a quiet cooler since it exceeds 25dB under load. My preference is under 20dB under load, but that is just my opinion.

Build this was used in:
Gigabyte GA-H97-D3H
i5-4690K @ 3.7GHz
Coursair Vengeance 8GB DDR3-1600
Gigabyte GeForce GTX980 WF
Seagate Barracuda 2TB HDD
DIYPC White/Orange Case

1 out of 5 eggsAsus does not Honor Rebate

Pros: Great Heatsink and fan. Keeps CPU cool. Install was a little tedious, but possible.

Cons: Six weeks after I was approved for the $10 Mail In Rebate, and I still have not yet received this Rebate.

Other Thoughts: I would prefer to have $10 off the product. All of the hoops they make you jump through for a measly $10, and then they don't honor this same rebate.

2 out of 5 eggsNot impressed

Pros: Works better than a stock intel cooler, and looks nice.

Cons: I used an i5-4690k at 4.4ghz with a Hyper 212 EVO at first, but I couldn't get the panel on my case. This CNPS9500 lets the cover fit, but temperatures are a little higher, and the noise is much greater!

Because other reviews mentioned problems with the 2 screws holding the spring to the square base, I paid extra attention making them tight in the captured nuts. After one trip however, one screw had worked it's way loose and fell out. The cooler was left bouncing around inside the case! Poor design using just 2 screws for the spring, and probably needs blue loctite from the start.

Other Thoughts: Compared to a Hyper 212 EVO, this cooler costs more, runs warmer, makes more noise, and falls apart.

1 out of 5 eggsHorrible support

Pros: Never got it installed (see below), so I have no idea how good it is.

Cons: One of the thumb nuts was missing the insert tor the bolts to screw into. I was going to purchase on in the store, but since this is a M3 nut, stores don't carry them; you have to buy them online,

Came with a rebate, so I couldn't send it back without invalidating the rebate with a replacement model; instead I submitted a request through Zalman to send me the nut or pack. I submitted it twice in a period of a week and received no email response from Zalman. Newegg gave me a phone number to, it didn't work. I couldn't seem to find one online, so I gave up and sent it back for a refund and got another cooler.

I have heard that Zalman's support was awful and this wasn't an exception. Poor quality control including a worthless nut along with the terrible support Zalman reserves one star on this one.

5 out of 5 eggsSuper cooler

Pros: Copper,
Easy to install,
Super quiet at low rpms

Cons: None

Other Thoughts: I have my motherboard setup to do CPU smart fan control so the fan doesn't go more than 1500 RPM and is super quiet. Stock E8500 @ 3.16 and idle temps are 30C in a 76F room! Prime95 small FFTs doesn't take it above 55-56C while still maintaining 1500 RPM! Arctic Silver 5 for the thermal paste.

5 out of 5 eggsBig Boy

Pros: Dropped 12C under load from stock cooler.
Adaptable to future socket types (I've owned two over the past 10 years, both are still going!)
For how big it is, it's quiet.

Cons: Cut myself on the fins. :(

Other Thoughts: I guess I'm bias, but everytime I do a new build, this goes in. Until I switch to watercooling I will always by this big boy.

5 out of 5 eggsPerfect for Old Dell Inspiron 530

Pros: Price

Cons: Big, but not too big
Loud at 100%

Other Thoughts: I just installed this in my Dell Inspiron Desktop with a Q6600 2.4Ghz overclocked to 3Ghz. Wow, it's running at 10C cooler and the fan bolted right into the mainboard with no need to remove it! So far so good! The Tuiniq TX-2 and Arctic Clean were used for the install and I'm happy with the results.

3 out of 5 eggsCools good .... install leaves a lot to be desired

Pros: Does a good job of cooling.... once you get it installed.
Doesn't hang over the motherboard making it a good fit in a tight case
Lighter than some other aftermarket coolers

Cons: Screws are too short
More components than necessary to mount the bracket
Plastic bracket
(see Other thoughts below)

Other Thoughts: Let me start this review by saying that my old Thermaltake cooler was much better than this and I wish I could have it back but the new case I bought was an inch too short to accommodate it and I didn't want to mess with returning it and getting a different case so I just bought a slightly smaller cooler instead.

First (and biggest) issue with this Zalman cooler.... the screws that are used to attach the retention arm to the mounting bracket are too short. The screws thread into a nut which is maybe 1/8" thick on the back side of the bracket and they only thread about 3/4 of the way into the nut. I put one screw in, tightened in, then put the other screw in and while tightening it the first screw popped right out of the nut. Even if you could get both sides tightened, I wouldn't trust it. I ended up finding 2 screws from my other Thermaltake cooler that were the same thread count and pitch but were about 3/8"-1/4" longer than the screws that came with this cooler. They threaded fully through the nut and worked perfectly.

Second issue.... the bracket is a bit of a pain to install. The mounting consists of the screw, a tiny plastic washer, and a nut. Way more components than necessary. My old Thermaltake cooler had screws that went in from the back side and threaded directed into the bracket. Not nuts or washers needed.

Third issues.....the bracket is plastic. While it is rigid plastic and will probably never break under normal circumstance, do we really need to take that chance in this day and age? Again, back to my old Thermaltake which had metal brackets.
