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: 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.

5 out of 5 eggs

Pros: Cool, quiet, LED is not too bright.
MSI Z87-GD65
Intel i7-4770K (no OC)
Arctic Silver MX4
Antec 1200

Cons: Installation wasn't easy, but wasn't absurdly difficult as others have stated. I bought with a new mobo so I this was the very first think I installed, while the mobo was still out of the case. DO NOT try to install this CPU cooler last - the included hex key already had limited range of motion with just the components soldered to the mobo. Inspect the direction pictures very carefully. Insert the hex bolt into the groove in the backplate and then secure it into place with the black plastic cover. I was able to easily do the install by myself after I figured out what to do - but I could see it taking two people if you tried to do it after you already had the mobo in the case.

4 out of 5 eggsBeefy cooler worth the trouble

Pros: Gives great temps (32C - 43C while overclocking). Some issues with installation but performance is fantastic. Not too loud at max in my opinion.

Cons: Requires surgeon like skills for installation. As many people have said, the AMD plates that attach to the heatsink base look crimped but are basically flat. I had to get out vice grips and pliers to bend them into the proper double kinked position. That said I was still able to get this sucker on without pulling the entire motherboard - took about 2 hours.

3 out of 5 eggsGreat.... Once you get it installed

Pros: It looks great, quiet and works well. I will say that.

Cons: Lets see..... where to start....... well a Snow White coloring book would have been more helpful than their instructions. The FIRST thing you need to know, and the first thing that should be in the instructions is INSTALL THIS BEFORE ANYTHING ELSE. I know it may seem like a good idea to install it last so you don't have to work around it's size but, no, do not do that. Once I figured out how to install it properly it was actually a fairly easy and clever process

Screws they provide strip after first use. Once you install this sucker you'll have a helva time getting it back out, I think the allen screws they give you are made of solder, or maybe clay. And the screws are right under vents (that could have a straight hole drilled in them, just saying) So everything is being turned in at a very awkward angle. It's a one way ticket for this fan.

It made a Whirring noise till I bent tubes a little, but it was real quiet after that.

Other Thoughts: Find a video of someone installing this thing first.
