The Zalman CNPS9900 MAX-R combines some of the most advanced technologies in the market used for CPU coolers to create powerful cooling performance. The CPU cooler utilizes composite heatpipe which is 50% more effective in transferring heat compared to ordinary heatpipes. Combined with a whisper-quiet 135 mm red LED PWM fan positioned between two massive nickel plated pure copper heatsinks, the CNPS9900 MAX-R is more than enough to satisfy overclockers and users who are looking for ultra powerful cooling performance in silent operation.

  • newegg Powerful Cooling Performance [Qmax: 300W] Optimally designed pure copper fins effectively disperse heat away from the CPU via composite heatpipes, while the high capacity 135mm fan quickly cools the heatsink for stable operation of high performance CPUs.
  • newegg Ultra Quiet 135mm Red LED Fan An ultra quiet 135mm fan is incorporated for minimized noise while the red LEDs heighten the cool aesthetics.
  • newegg Black-Pearl Nickel Plating The entire copper heatsink of CNPS9900 MAX-R is ‘Black-Pearl’ Nickel Plated for long-term corrosion resistance, while the deep ‘Black-Pearl’ tone along with the high intensity red LEDs reinforce its powerful aesthetics.
  • newegg PWM Fan Speed Control The PWM (Pulse Width Modulation) fan automatically adjusts fan speed according to the CPU’s temperature, while the included Resistor Cable (RC7P) provides the option of reducing the input voltage for overall reduction of fan speed and noise.
  • newegg High Performance Super Thermal Grease ZM-STG2 The included all new high performance thermal grease ZM-STG2 maximizes heat transfer from the CPU to the base of CPU cooler for intensified cooling performance.
  • newegg Versatile Compatibility The CNPS9900 MAX-R accommodates a broad range of CPU sockets including Intel LGA1156 / 1366 / 775 and AMD AM3 / AM2+ / AM2.

4 out of 5 eggs

Pros: Keeps my i7 4790k very cool at around 30C even under CPU intensive programs. Compared to the stock cooler which hovered right around 60C, this thing is a definite improvement. The general build quality seems quite high, with the piping and heat sink and fins all looking very nice. The black finish that has been applied to the fins is a nice touch as it also dulled the edges so it's much harder to cut yourself. It's 'improved cooling effect' might be just marketing, but it still looks and feels great. Installation was fairly straightforward and didn't take more than twenty minutes.

Cons: The instructions are worthless, don't even bother attempting to read them (except in identifying your screws relative to your socket type). There are plenty of Youtube videos with step by step instructions that are ten times better and simpler to understand.

The screws are not separated by socket type, nor is anything really packaged. It's like the company just tossed in the components without any real thought to organizing.

The red LED is laughably dim, barely noticeable unless it's completely dark. I knew other users had mentioned this but figured it was just luck of the draw - if so, then I just became a statistic. Don't bother javascript:Biz.Feedback.RateProduct.Form.submit('display')if you're looking for an 'in your face' LED.

Other Thoughts: The installation isn't overly difficult, it's just tedious and requires some patience and steady hands. Users who call it impossible or a nightmare clearly went wrong somewhere. I'm not mechanically inclined in the slightest and I managed to do it fairly easily; the hardest part was fishing out dropped screws or the occasional Allen wrench (which is magnetized by the way). I didn't even need to remove my board from the case(CPU cutout), just the video card and RAM so my hands could work.

It's a honking cooler but fits very snug inside my rig with reasonable clearance from all components. If your motherboard has her RAM slots to the right of the processor (looking at it installed head on), you'll be just fine; the fin arc runs parallel to the RAM slots, so tall heat spreaders shouldn't be an issue. It will also give a fair amount of room between it and any video card in that first PCIe slot.

Overall I couldn't be happier; I wanted a step up from the stock cooler without going overboard, and this seems to have fit the bill. Installation is tedious but not difficult and can be done with just one person. If you have a side panel fan, be weary that this thing is quite tall and could interfere. Don't use a lot of thermal paste, and make sure you're using the correct screws for your socket. A lot of common sense stuff really.

5 out of 5 eggsGreat Cooler!

Pros: Decided that I was too lazy to take my motherboard completely out so I left it in and did the install. It was actually quite a bit easier than I expected, had to take a couple of my RAM cards out to get the screws in, but was only ~30 minute install. With my stock Intel cooler my CPU was idling at about 40c. With the Zalman I'm sitting at 27c idle temp. Doing the full OC test only brought it up to 40c. And last but not least, it looks awesome

Cons: It's not something that I'll take off an egg for, but it just BARELY fits into my Rosewill Blackhawk ATX tower. The top of the heatsink sits about 1cm away from the fan on my chassis door.

Other Thoughts: Any other problems arise and I'll let you know, but so far this is an awesome product.

5 out of 5 eggsZalman CPU Cooler

Pros: Great looking CPU cooler, easy enough to install, did not cover any of my ram slots, and keeps my CPU cool, what more could i ask for. Good Price.

Cons: Doesn't seem like you can change out the fan.

4 out of 5 eggs

Pros: I like the look of it, the fan design is different from most coolers and the nickel plating and red led are a nice touch. Although there aren't many heatsink fins it does a good job of keeping temps down.

I have an i7-3770k running at 4.4Ghz @ 1.3 volts (appr) and the prime95 max heat test is at 90c

Cons: Installation wasn't the easiest. And the fan is not very quiet. I use speedfan to keep it running as slow as possible, and at that speed it is quiet.

Other Thoughts: I have an i7-3770k running at 4.4Ghz @ 1.3 volts (appr) and the prime95 max heat test is at 90c. These temps are never seen during gameplay or normal usage but I use them to test my overclocks.
The blend test gives me roughly 77C.

Regarding the fan speed, from my testing, between low and very high fan speed there is considerable noise but very little temperature difference.

4 out of 5 eggsZalman Torridal Cooler

Pros: Cool look. Well made. Keeps my Intel 4790K at about 23-27 Celsius at idle with Arctic Silver 5. Gaming only adds about 15 degrees. Have not done a torture test yet. Have not overclocked the CPU either. Clears heatsinks and ram with room to spare.

Cons: The mounting solution is adequate for the job, but is miserable to try to install on a mounted motherboard. Pulling the board helps tremendously. The fan on mine is slightly out of balance. I can see it quiver while the fan is running. Less one egg for that.

2 out of 5 eggsInstallation & Mounting from Hell

Pros: -Looks good
-Doesn't interfere with memory slots
-Not too heavy

Cons: -Fan assembly can easily be bent out of place (or broken off entirely), also impossible to replace the fan alone
-Installation instructions are not very clear
-Mounting screws strip very easily, even with the provided allen wrench
-Allen wrench does not clear the average motherboard heatsinks while tightening things down
-Included TIM is low quality, feels like spreading silly putty onto your CPU (with about the same thermal conductivity)

Other Thoughts: One of the four mounting screws stripped completely before I could even tighten it down all the way. I can't be 100% sure that this is the cause, but my temps very unstable, and running a Prime95 test is causing my CPU to throttle itself down due to extreme temps.

I'm sure this would make a great cooler for the money if it could even survive it's own installation.

Will be ditching this and going for a watercooling setup that will have a lot less nonsense when just trying to mount it to the CPU.

5 out of 5 eggsLong life == true

Pros: Extraordinary build quality!
Long life!
Wonderful cooling!
Looks awesome!

Cons: Somewhat challenging to install.

Other Thoughts: I have had this CPU cooler for two years now, and it is still humming along perfectly! In fact it has been in 3 different computers. During heavy gaming my rig's CPU rarely strays above 40-50 degrees celsius.

The only downside to this CPU cooler is that it can be difficult to install, and some CPU cases might not give you enough clearance behind the motherboard to fit the bracket that attaches to the back of your mobo. Nothing a little dremeling can't fix.

But the counter point to this is...once it's on there, it ain't going anywhere.

5 out of 5 eggsCools like a champ. Best option next to liquid loop

Pros: Keeps a ~4GHz clocked i7-4770K (with Céramique™ 2 TIM) idling @ ~30C and ~54C after full load for hours. I expect this will improve too as the TIM bakes in. Currently on day two of my typical seven day bake in.

Since it is not a liquid loop system, no risk of leaks. Infinite stars for this...

Given the dimensions and mass of this unit, installation was quite easy. I've installed many aftermarket coolers that were 100x harder and felt less secure.

This unit mounts very securely and after seven days of thermal cycling (in a CPU relative horizontal position to ensure good TIM distribution), I will have no worries setting my chassis upright. The mounting system is secure and distributes load very well.

The fan is fantastic (gosh that is a bad pun) ... at idle and normal workload it is effectively silent. At full load it becomes audible but not annoyingly so. Once the load is removed, CPU temp and fans speed drops RAPIDLY back to idle condition. Very impressed by the thermal soak and dissipation capability of this cooler.

Oh, and the looks. I have an MSI mobo with a black & red theme and this cooler is such a perfect match. Visually I could not be happier.

Cons: Zero, none and nada.

Other Thoughts: Measure HxWxD first and be aware this thing is heavy. Trust the mounting system. Enjoy the amazing feels.
