  • Summary: This is an amazing CPU cooler and worth the money. Make sure to take note that Socket 1150 is the same as 1156. 1150 is not listed in the instruction set and it was one of my first times adding a backing plate to the motherboard.
  • Pros: Amazingly quiet even without the "silencer" with it. Temps rarely get above 30C even under full load (i5 4590).
  • Cons: Size is the number one con. Make sure the motherboard you are pairing this with has plenty of space between CPU location and RAM slots. I cannot use two RAM slots on an ASRock Fat1lty Z97 Killer motherboard

a monster

Jared P., Newegg

  • Summary: i suggest buying a smaller cooler. zalman will always have a place in my case and they did a good job at explaining how big it was in the description. but i didint realize how big it was untill i saw the box. and it was nearly the size of my head. LITERALLY. like a 7 year olds head. its huge. its as tall at a 12FL oz glass bear bottle. pretend your PSU is your cpu heat sink. THAT BIG.
  • Pros: its big and plenty of airflow. probably one of the best short of liquid cooling. blue is my favorite color. and its not loud. even with 3 fans
  • Cons: its BIG. if you want 4 sticks of ram dont buy it. i had to use both channels A and B of my ran just so i can fit the cooler in the case. but no big worries. it is what it is. it wont get 5 eggs because i cant use the other 2 A and B slots of my ram. im useing the ASUS sabertooth 990 MB

It's good, but...

Aaron H., Newegg
24 February 2014
  • Summary: If you do buy this item, make sure you measure your case and have the room for it.
  • Pros: It worked well to keep the CPU cool.
  • Cons: I have a very large case, ATX super tower, and it did not fit in my case. I ended up returning it because I could not close my case.

Quiet Cooling

Jason C., Newegg
18 December 2013
  • Summary: The triple fan is nice, but wish it wasn't as wide and higher off of the board to clear memory with heat sinks on.
  • Pros: Does a great job at cooling and very quiet. I've never heard the fans kick on to full speed during intense gaming. Intended it to be a temporary solution until I could go with water cooling but it performs so well I never needed to.
  • Cons: Very large and covers up memory and 1st PCI-E slot on my ASUS Rampage IV Extreme board.

Very quiet

Brian W., Newegg
20 September 2013
  • Pros: Super quiet. I can barely hear this fan.
  • Cons: Started rattling after a few months and had to send it back. It took over 3 weeks to get a replacement but was under warranty. It's huge and blocks my RAM slots on my motherboard.

  • Summary: I bought this fan because as I suspected, despite the very large size it works well with my case... Old Cooler Master full tower steel case with two top mounted 200 mm fans. I was able to mount the whole assembly 'sideways' so that it blew the air out of the top of the case through those 200 mm fans. This also avoids the "covers my RAM slot" problem to some degree, although it infringes upon the first PCI-E slot on my Maximus VI Extreme motherboard.
  • Pros: Wasn't as hard to mount as I feared at first, follow the LGA 1555 instructions, and it will work fine if you have a Haswell chip/motherboard. Same spacing for holes = same mounting procedure.
  • Cons: Even when it's on firmly, it feels loose. See other thoughts for more tails. I removed an egg for this, because despite having tightened the screws as hard as they'd go, it doesn't /feel/ like it's mounted properly.

Keep i7-3770K Cool

Joshua B., Newegg
15 June 2013
  • Summary: All in all this is a great cooler. Keeps PC nice and cool under All conditions.
  • Pros: Keeps i7-ivy bridge 3770k cool. Cores are 29 C at idle and 68 C at full load at 4.5Ghz Very Quite Easy to Install
  • Cons: The cooler allows for a slight rotation after installation The cooler fins are flexible and may make contact with the fan (horrendous noise easily solved). The cooler only has a 3-pin fan and not a 4-pin header

Super quiet

Curtis B., Newegg
14 May 2013
  • Summary: Works great and is super quiet. 4 eggs though because the thing is so large and heavy. If you plan to buy this, be sure that any heat sinks on your RAM are low profile. Also, the weight of this thing really made me nervous at first. It wouldn't be a big deal if your motherboard is sitting horizontal, but standing it up in a tower made me worry that it would bend the motherboard and damage it in some way.
  • Pros: Very quiet. Cools like a boss.
  • Cons: Absolutely massive. Very heavy.

Good concept that needs some refinement

Alexander D., Newegg
20 October 2012
  • Summary: Zalman could have had an amazing product, but ultimately the CNPS12X falls short of what it could and should be. While it's still a good cooler, I can't say I'd recommend Intel users give up their third channel of memory for a heatsink that's only slightly above par. It's working very well for my specific needs, but most people are probably better off with a NH-D14 or one of the Phanteks coolers.
  • Pros: This thing is a beast! This past year I've gone through three coolers (including this one). First was the Thermaltake Frio, which was a decent cooler but didn't fit inside my case. Then there was the Zalman CNPS9900MAX, which was a lesser cooler to be sure, but much smaller which was my main concern at that time. Fast forward six months, and my pristine 9900MAX gets damaged during my move from California to Florida. I'm now in the market for a new cooler and I want so...
  • Cons: As many other users have pointed out, this heatsink will interfere with your first RAM slot. This was not an issue for me personally since I only run dual channel memory, but Intel users running triple channel may want to look elsewhere. Installation was relatively simple since I have an AMD system, but to say that this thing barely fits is an understatement; it's pushing against my second RAM stick (G.Skill Ripjaws X), and I had to slightly tilt the heatsink in order...

Zalman fan

Brian K., Newegg
10 October 2012
  • Pros: I have several of these in many machines, and they are pretty quiet and efficient
  • Cons: On more than one occasion, with different fans, I've had to insert a screwdriver in the side of the center fan, and force the fan blades back onto the shaft in order to get them to spin. Once I do that, they work fine. Something of a quality-control issue, but not a deal breaker. I'll keep buying them as it is an easy fix.
