1 out of 5 eggsDON'T MAKE MY MISTAKE

Pros: It can light up, red, and it shouldn't

Cons: It worked well for a couple weeks, but only if I was surfing the Web or listening to music, if I tried to play a game it would provide little to no cooling, and start glowing red (which I can't find what it means ANYWHERE) but I know it's not good, then (and here's the icing on the cake) when I tried turning my computer on, a mist was shot out like a febreeze air freshener, and it went straight to red right out of being it's normal green. Now I am shipping it back and I better get a refund.

Other Thoughts: Oh yea it comes with a glitchy software that doesn't work, and won't acknowledge the kraken as being in the computer. And yes it was installed correctly, just the product and the software for the product SUCK. (also I had to type this review on my phone, so that shows my frustration at the moment, which is 2:17 in the morning

5 out of 5 eggsAmazing

Pros: I'm extremely happy with this product from NZXT. Great quality product worth the extra money compared to other close loop coolers.
the 140mm radiator is awesome supplied fan is quiet and high quality. My idle temps are 31c and full load is 60c on silent mode. haven't fully tested performance mode yet. (5820k Stock@3.3)

Cons: Only con's i can think of is the pump can get slightly loud when switching from idle rpm to full rpm then it returns to normal, The other one is the led logo stays on even when your pc is powered off, there are a few fixes for this that involves bios settings for power saving features and the final Con is the lack of good paper instructions you must go to their website to get the full instructions.

Other Thoughts: Overall a great product and outstanding warranty! For those hesitant on liquid cooling this would be a great first product. User friendly and easy to install with pre-applied thermal compound no need for any additional steps.

1 out of 5 eggsKraken X41

Pros: Since I have installed it i have not have not gone above 35 degrees.

Cons: I had to modify (Destroy) my case for it to fit. Once it was installed the fans weight was off. It kept scrapping the sides. The thermal paste that was contained on it was all over the packaging. The plastic covering was not on properly.

Other Thoughts: All fans should be tested by the manufacture before being shipped out.

Manufacturer Response:

4 out of 5 eggsKraken X41

Pros: This keeps my 4790k at 23 to 27 degrees on idle, when playing any games with my processor oc to 4.5 it never goes above 38 degrees. The led light feature is very eye pleasing with an open case.

Cons: I knocked one star because no matter what the CAM software will not recognize the unit. it does not worry me because I can control the speed with my ASUS AI suite 3.

Other Thoughts: this is a great unit I reccomend it.

5 out of 5 eggsMy ideal cooler

Pros: I have used this thing on an 8350 @ 4.7 Ghz 1.47 V and am now using it on a 5820k @ 4.2 Ghz 1.3 V. Kept both plenty cool under prime95, 8350 got to like 50 C on core temp and 5820k gets to about 60 C on cores. Stock fan is quiet under idle but gets pretty loud under full load (stress testing). Replaced with noctua fan and got much better performance. Pump is inaudible in a define r4 case at lowest pump speed.

Cons: CAM software was a horrible mess at launch but now it works pretty well. Only problem was had to use mobo as fan controller as CAM software uses liquid temps and they vary from 30 C at idle to 39-40 at load. CAM only allows fan settings at 20, 30, 40, 50 C, etc. This would limit me to 2 fan settings which is a terrible idea. Like I said, easily fixed by using the mobo to control cpu.

5 out of 5 eggsVery effective. Worth the price.

Pros: - Fits VERY snugly in my H440 chassis
- Customizable LED that can change color to indicate high temps
- Come with thermal paste pre-applied
- Easy to install
- CAM software/driver is easy to use and navigate
- Keeps my 4690k @ 4.5 GHz at a nice 40 degress while at max load (25% fan speed)
- Looks hella sexy (except for tge fan)

Cons: - $8 stock fan is ugly.
- Tubing is a little long, but not overly long.

5 out of 5 eggsAdustable LED colors

Pros: Overall, the cooling is about 5 degree's centigrade cooler than the stock fan when the CPU is overclocked and the demands are taxing . It does this with fewer decibles in noise but for liquid cooling this is anticipated. The best part is the LED feature thats allows you to change "colors" of the light. If you're into color matching rigs,. this is it.

Cons: The 140mm size takes up two 120mm fan spaces.

Other Thoughts: Aesthetically, it's the best looking unit around but I wish the fans were traditional black in color rather than white.

5 out of 5 eggsYAY!

Pros: IT COOLS!

Cons: I don't know, I don't care!

Other Thoughts: I had a H100i that had some sort of issue, because I was only seeing a max of 5C difference from the stock fan in both idle and max load temps. So far, the x41 has been beating that by another 5 degrees! Woo-hoo! I've still got to run this through its paces, but I'm happy. I also like that I can change the LED color and everything easily with CAM

4 out of 5 eggsNice Cooling, Not Silent.

Pros: Great at cooling, assuming the thermal compound is decent. I did not replace it with Arctic as NZXT seems to have their stuff together.
When the unit is running high RPM to keep my temps down the fan makes noise. Which is fine.
When the PC is not hot and the unit should be dead silent.... the water pump makes a fish pump noise. It is loud enough to hear even when the 6 six feet from the PC. The fan is quiet but the pump clearly doesn't like being idle.

Cons: Software doesn't read temps or RPMs well or accurately. I wouldn't trust it at all. Fish pump noise on water pump when running slow.
