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! Love it.

Pros: Keeps the CPU cool, very low noise, long life. Love the quality

Cons: Had to remove the motherboard to install it but well worth it

Other Thoughts: Have the Zalman CPU cooler installed on my PC for 7 months as of now. After checking multiple CPU coolers to replace the stock one I had, I went with Zalman. My decision of purchasing a cooler was based price/quality/efficiency. Had some friends recommending a Zalman cooler, as some had them installed on their PCs. Best PC cooler for the price range.

My build- ASUS Z97-E/ i5-4460 3.2GHz/ 12 GB Ram/ XFX Double D Radeon R9 280/ 128GB & 256GB SSDs/ XFX TS Series 550W 80+ Gold PSU/ Zalman CNPS9500 cooler

Installation- It wasn’t that hard but it wasn’t easy as well. It was my first time installing anything(my first build). Had placed my motherboard to my case due to already having a backplate placed on it. Tried to install the cooler with the mobo placed and just couldn't place it. It was due to the size of the cooler and couldn’t place my hands properly in the right positions due to the case. Once I removed the MoBo I managed to install it real fast. So this was the only inconvenience I had with the installation. I didn’t use the provided thermal paste, used the Arctic Silver 5.

Quality- No complaints here. It’s sturdy and well made. The fan doesn’t make any noises unless it’s under high duress (I only hear it when updating my graphics card- it’s under a high load). As for temperatures when idling my PC is always around 28C-30C, with light use between 30C-32C and when gaming never saw it go above 40C-42C(even when streaming). It does go around 50C whenever AMD does an update on the graphics card(all my fans go crazy).

Overall I’m very happy with the cooler. The price/quality fits perfectly, it doesn’t make noise unless under heavy load, keeps my CPU cool. Would recommend this cooler to anyone.

1 out of 5 eggsNice HSF, but don't be suckered by Rebates

Pros: As usual, Zalman makes excellent HSF for overclocking enthusiasts. I had its sister, the CNPS9900MAX, in my last build, and while they're both very large chunks of metal, you cannot argue their effectiveness.

Cons: It's a very big HSF, so it won't fit in many cases. Installation can be a little cumbersome, so it might be easier to remove the mobo prior to mounting. Also, rebates suck.

Other Thoughts: I paid a little more than it usually sells for, because Zalman promised a rebate through Par for course for the dreaded "mail-in-rebate," they claim they didn't get my documentation, and requested I re-send. Of course I don't have a second UPC to mail, so I'm out $25 because of yet another shyster rebate company.
Rebates: Not Even Once.

5 out of 5 eggsIf you have space, you must buy it.

Pros: Excellent cooling. Previous temps were a bit high, running around 75C, even higher with shadow of mordor. With this thing, running on average 45 to 50C on ultra settings. If your tower has the space, just spend the 35 dollars.
Excellent price for performance. BUY IT.
Not even that loud.

Cons: Not too much to say. It was a little tricky to install. However, the process seems necessary for a heatsink of this weight.

Other Thoughts: I would absolutely recommend this to a friend. I enjoy the choice of either an LED lit fan, or this more simple cheaper unlit one.
I don't see a reason to buy another...but if I had too, I definitely would. Design is great, the mounting brackets hold it well it place

1 out of 5 eggsMounting horror

Pros: I was unable to get the heat sink installed so i can not say on its performance like others have.

Cons: One of the worst mounting installations i have seen for a heat sink. There are just 2 tiny screws meant to hold the heat sink onto the cpu. Needless to say they did not work. I was using a 775 socket. The metal nuts meant to hold the screws gave no retention what so ever. I will be asking for a full refund for the product. I am more than disappointed.

Other Thoughts: I have built 5 computers from scratched and have taken apart fully at least 10 times to work on them. With that said i have never had such issues with any heat sink like i have this one. I would advise to not get this product the support structure for the heat sink is not sufficient.

4 out of 5 eggsGood and Quiet

Pros: Keeps my CPU nice and cool, it's also very quiet.

Cons: The installation wasn't hard it was just annoying, honestly I never had a more annoying heat sink installation than this.
The fact someone saw that and said it was good is crazy.

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.
