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.

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
Quality
Packaging

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.

3 out of 5 eggsthe actual fitting

Pros: Grabs the heat from my CPU very nicely.

Cons: I had to buy another adapter ZM-CS4A, because I have an lga1366 mobo. Whatever. But the problem is, there is absolutely no way you can get the screws into the bracket. On the front size, they are just too far back the screws never reach. I managed to get the top two screws to hold after removing the socket washers. Even then the bottom screws don't go in and it kinda hangs there. I'll need to go to HD or LOWs, to get longer screws. Gah!!!


Oh, and the fan doesn't work. I'll try running my CPU at it's max, to see if it works on a certain voltage or something. I'll update as soon as I find out.

5 out of 5 eggslightweight and extremely effective.

Pros: Very effective cooler that doesn't weigh much more than an Intel retail cooler. It doesn't require a plate on the back of the motgerboard, just 4 nuts to secure the mounting frame. Because of the way the frame is designed, you can orient the cooler 4 different ways to direct the airflow as you wish. With the retail cooler I was experiencing 99 degrees C running folding@home on a core2 duo E7200 at the stock 2.53ghz. With this cooler I am able to run my system perfectly stable at 3.8ghz at all times and never exceed 55 degrees C.

Cons: Large physical size makes it challenging to mount the cooler while the motherboard is installed in a case.

5 out of 5 eggs

Pros: Dropped my I7 4790 from a max of 85c with the stock Intel cooler to 62c doing heavy trans coding.

Cons: None

Other Thoughts: If you're so mechanically inept that you can't put in 6 screws without messing up you probably want to look elsewhere. Complaints of getting cut and using heavy gloves? Really? If you're that ham fisted ease up a bit, probably help with the stripped screws too. Seriously, they're 3mm; you don't need to wrench them down. Snug is good.

1 out of 5 eggsWORST CUSTOMER SERVICE EVER

Pros: It SHOULD work, but there is a problem. See below.

Cons: I found a defective workmanship on the item that did not allow the screws to fit snugly, causing the HSF not stay on the CPU. I emailed Zalman

subject: Defective ZALMAN CNPS9500 AT 2 Ball CPU Cooling Fan/Heatsink

Hi,

I purchased two ZALMAN CNPS9500A-LED 92mm 2 Ball CPU coolers and one ZALMAN CNPS9500 AT 2 Ball CPU cooler. The two LED versions seem to work well. The CNPS9500's thread was broken upon arrival. You can imagine how upset I was when I spent time putting my entire system together just to find out the screw to one side of the mounting bracket. I have to take the entire thing apart and put in a different CPU Fan/HS.

What's wrong with it? If I put the gold screws into ANY other place, it works great. In fact when you place the screw in, you can see it stops about 3/4 the way in, allowing you to screw it. What's wrong with it is one side doesn't do that. You put the screw in and there's absolutely ZERO friction. In other words, it doesn't hold anything! It keeps coming loose.

I looked at my LED versions and all the screws all stop about 3/4 the way in.

I need a replacement bracket. This CPU Fan/HS is totally worthless without the threads working properly!

I have attached my Newegg invoice to show my address and receipt.

I GET NO RESPONSE FROM ZALMAN SO I REPLY TO THEIR EMAIL AGAIN:

I know what the problem is. I looked at the under side and what normally would fit perfectly, the 6-sided lug nut isn't in perfectly. It's actually rotated slightly halfway, causing it to be jammed in not all the way. From the under side, the metal nut is on almost perfect flat levels with the plastic bracket, whereas the other sides are down deeper, sort of like a crater. I tried to put pressure on it to move it down deeper, but it's not going. It's stuck real good.

AGAIN, NO RESPONSE SO I EMAILED AGAIN:
