5 out of 5 eggsAmazing cooling

Pros: Running an AMD FX-6350 at 4.2 Ghz, idling at 24C. I built this rig to play Star Citizen, as my older PC just couldn't cut it. Playing SC Arena Commander with maxed out settings, the CPU tops out at 45C. My GPU is a GTX 970 and it gets up to 70C. I'm astounded that an air cooler can keep the CPU so cool. Room temperature is around 19C.

Installation was not difficult. I just followed the directions, and made sure I had enough room before I ordered it.

Cons: It hangs over two of my memory slots on my Sabertooth 990FX MB, however, it does clear the low profile RAM. I have all 4 slots filled, but I would have to remove the HSF before I could remove the RAM. Not a big deal for me as I don't intend to remove it, but it is worth noting.

Other Thoughts: I would recommend installing this cooler on the MB while it is out of the case. Also, make sure you have your RAM installed BEFORE you install the HSF.

I have another Zalman HSF on another rig in the house, and it has performed flawlessly for over six years. This cooler already performs better than the old one. I hope it lasts as long! I'm sold on Zalman coolers.

5 out of 5 eggsCooler temps

Pros: Bought this to replace the stock heat sink and temps dropped considerably, went from 70C to 39C idle. With heavy use, temps climb up to about 43/44C

Cons: None/ Installation was easy and took less than an hour. Hearing how troublesome this heat sink is to install from other reviews I was hestitant in buying it, but I'm glad I did/ Fits well inside my Full tower case

5 out of 5 eggsBuy this if you have ANY AMD processor

Pros: Very quiet, Looks cool, and keeps my processor nice and cool. I have an AMD 8350 and it came with the stock, 40mm fan. When I play a game like, Arma 2 for example, The stock sync made it sound like it was a 737 starting up. the highest temp before I decided to buy this was at 70 to 75C. and started to De-clock itself. When I bought this, I rarely see it get over 55c. Average in Arma 2 now is 45 to 50c. After two years of owning this heat sync, I still do not have any problem

Cons: The sync is huge. If you have a mid size case, you may run into issues with room. If you have a large case, you will be fine.

Other Thoughts: Because of this product, I am not a satisfied and returning customer to Zalman products. If I have any issues with heat with a different computer, I will but a Zalman product.

5 out of 5 eggsGreat fan

Pros: Great looking fan even though it is huge. runs quiet and is not hard to install like some of the other reviews have said. just make sure you install it to the motherboard before installing the motherboard to the case to make it easier on you. getting idle temps on my overclocked i-5 at 32c

Cons: would have been nice to have the thermal paste pre applied.

Other Thoughts: easily fits in my thermaltake chaser a71 case

2 out of 5 eggs

Pros: First day it booted up, noticed a change in my CPU temps right away, 20C cooler.

Cons: The installation is horrendous! I could hardly keep a nut in place to put a screw down in the cooler. And I don't mean to be rude here, but what kind of jerk makes a cooler taller than the case itself, with the board re-fitted and everything? I only got space for "139 mm"!

Other Thoughts: What's even worse is, I couldn't use my two fans I bought with the order I got, Item N82E16835181025.

It's that honkin' huge! It's like installing a jet engine to your CPU. And I thought I read on here that it was compatible with FM2. The box itself, and even the manual said otherwise. And because I couldn't screw down anything using the enclosed brackets, I had to fall back to using the motherboard's back plate.

If Zalman had made a smaller cooler (92mm/120mm), then I would have put it in my case, but I still couldn't use the fans I got.

Plus, it's blocking some of my RAM slots, so now I won't be able to upgrade anymore.

5 out of 5 eggsI'm "blown" away.

Pros: Excellent air flow and solid heat transfer.
I was idling at bios at a temp of 78°C with my stock cooler. When I bought the Zalman CNPS9900 and installed it, the temperature dropped to an ice cold 33°C with no load. Definitely a solid buy if you have the space and need to cool a CPU

Cons: Somewhat difficult to assemble, but nothing that can't be figured out by using common sense.

Other Thoughts: The Blue LED is pretty awesome. Could be brighter on the front side, but otherwise pretty sweet.

1 out of 5 eggsBig hopes, was very excited, but disappointed in the end

Pros: I'm a long time Zalman CPU cooler user, so when I went looking to build a new PC, a Zalman CPU cooler was on my list. The radial design looks great. The LED fans look great. The design lends itself to have plenty clearance from the RAM slots.

Cons: The specifications shows that the product is compatible with my motherboard (Asus Maximus VI Formula) and chassis (Thermaltake Chaser A-71). However the install kit is a nightmare.

Install Kit issues:
- The mounting nuts used to attach the back plate to the under side of the motherboard slip out of the holes really easily.
- The sticky tape used to hold the back plate in place acts like a spacer between the mobo and the back plate. With the extra space between the motherboard and back plate, the mounting nuts barely protrude though holes.
- The screws, that are used to mount the cooler to the backplate, sit about 1/2 to 3/4 of an inch above the motherboard. It seems excessive downward force or compressive force is needed just to get the screws to make contact with the nuts that barely protrude thought the motherboard holes. I did not want to apply excessive force and I generally don't like to force-fit components, so I halted my install.
- Zalman includes an Alan wrench for tighenting the screws. However, with the physical force needed (described above) an extra set of hands is needed to work the Alan wrench.

I'm willing to bet that if Zalman included the mounting kit from the CNPS9700 LED product, the 9900 D/F install would be a breeze. There is an intuitive install video on Zalman's site for the CNPS9700 LED product, but not the 9900 D/F product. I sent an email to '' on 1/3/2014. As of 1/15/2014 there has been no reply from their customer service or technical support departments.

Ooh... Zalman has an All-In-One water CPU cooler product with that radial design. No thank you... not taking any chances with Zalman at this point.

*** This ended up being a big disappointment. ***

Lastly, the middle fan was bent/leaning toward the rear heat sink. It arrived that way due to shipper rough handling. To the RMA department it goes.

Other Thoughts: I replaced the item with a CoolerMaster Seidon 120m All-In-One Water cool product for less than the Zalman?!

Seidon 120m = super easy, brainless installation.

Manufacturer Response:

Dear valued customer,

We sincerely apologize for the issue. Please contact our customer service e-mail or via toll free number 1-888-925-6266 for further assistance.

Thank you.

Best regards,

Zalman USA Customer Service

2 out of 5 eggsZALMAN CNPS9900 D/F 140mm & 120mm Long Life Bearing Dual Fans Ultra Quiet CPU Cooler

Pros: This CPU Cooler has a solid build and looks great.

Cons: n/a

Other Thoughts: Newegg advertised this item as "Intel 4th Generation Processor Ready" but it is definitely not. I bought the mobo 1 x MSI Z87M-G43 LGA 1150 Intel Z87 HDMI SATA 6Gb/s USB 3.0 uATX Intel Motherboard from newegg for my new system. When i tried to fit this cpu color on the dimm slots were too close. Once you put the ram on the cpu cooler, the cooler would be blocked by the ram around 1 inch. When i called newegg to RMA this back due to false advertising the rep. would not waive the shipping fee to send the cooler back. Very disappointing since it was false advertising on their part when newegg stated on the ad as "Intel 4th Generation Processor Ready" when it was not in this case. SO BUYERS BEWARE!

Pros: Looks great. Amazingly quiet. Running this on MSI 990FXA-GD80 with AMD FX 8350 in an Antec Twelve-Hundred Case. CPU temp stays at 38-39 normally, 48-50 during gameplay. Had it almost a week now have not seen temps go above 50.

Cons: None at all, this is a great product. So far its passed every test but time.
