Pros: Whisper quiet, and keeps my i7 super cool. This was far superior then the aftermarket fan that is suplied with my processor. Which as I am learning needs to have a robust cooler much like this Noctua.

Cons: When reading some of the reviews and performing my own self measuring no way did i figure this thing to be this large. I have a full tower which I am very happy i have, if not it probably would not fit.

Other Thoughts: One thing I had discovered during installation was i did not need to install both fans to keep the processor cool. This was great because it reduced the power consumption and reduced the sound, not that it needed to.

Pros: I'd have to say the highlight of this kit is the mounting system. It uses a clever (and initially a bit confusing) bracket system with a back plate for a positive stop attachment to the CPU. No need to worry about too much or too little torque as it's preset. When you hit the stop that it's job done pretty much idiot proof once you figure out how all the bits go together and the documentation uses very clear illustrations to helo you through this.

Cons: It is a good size cooler but coming from a V10 (now that's huge) I wouldn't say this was extraordinarily large. See other thoughts though for a bit of a snag I hit. I won't dock this cooler for it but you should be aware of this.

Other Thoughts: This is a very well thought out and engineered system to be sure. They even include vibration dampening strips that adhere to the fans so they don't transfer their vibration to the cooler thus keeping the sound down. This dampening strip caused the rear most fan to protrude enough that it was actually putting pressure on the A1 RAM sttick causing a failure to POST. I'm going to take the hit for this one as I could have mounted the strip a bit more inboard and it should have been fine. Just be aware that you are going to be very, very close to the first RAM stick on a Rampage II Extreme. Can't speak for any other board. All things considered I;d say this is an exceptional air cooler and very well suited for modestly overclocked i7 systems.

Pros: This CPU Cooler is really nice and i don't know why people say is hard to install cause i installed in less then 20 minutes and it takes 20 minutes cause you need to take the motherboard out. My temps are normaly 40c and when the cpu is 100% goes to 70c and im overclocking from 2.6 to 3.6 (Intel i7 920) am very happy with this product .

Cons: Nothing

Pros: Lowers my core i7 cores by 15C easy. Doesn't add much noise, my temps not doing anything are at 40-46C. VERY TALL. Barely fits my case, and i have the largest one, that's because of the proc placement on the mobo too.

Cons: none

Pros: quiet quiet quiet. not as heavy as i thought it would be. mostly easy install. if you want a silent pc without going to liquid cooled this is a good option.

Cons: Attaching the fan clips to the bottom were the only difficulty to the install. they created a bit of a sweaty brow moment.

Other Thoughts: If you're building a HTPC or DAW as I am this is an excellent option.

Pros: -Includes 2 120mm fans
-Runs very quiet, even with both fans installed and running at full speed
-Keeps my OC'ed i7 920 very cool

Cons: -Very large. Don't let the pictures fool you, the reviewers on this site are NOT exaggerating. Be sure it fits in your case before purchasing.

-While instructions are clear, make sure to pay very close attention to the pictures, as there is not much in the form of written instructions describing how to install it. If you don't pay attention the pictures, you may initially install it incorrectly.

-Fan color leaves much to be desired.

Other Thoughts: Great cooler. Works wonders and provides excellent cooling to the CPU. Large fans can help overall airflow in case.

Pros: quiet with both fans installed and pushing 1400rpm

Cons: Idle: 37°C
Low Load: 39-42°C
Med Load: 44-46°C
Heavy Load: 47-49°C

got the i7 920 up to 52°C running 8M on SuperPi

Other Thoughts: If you like quiet and don't plan on overclocking or doing anything that requires heavy cpu loads this is will work.

If you OC or run heavy apps you might want to replace the fans that come with this with some vantec tornados for higher CFM's (unless you're smart and go with water cooled)

Pros: Its quiet, it cools like I have never seen before, looks good and does it job fantastic. I am totally confident in buying this cooler.

Cons: none but read "other thoughts".......

Other Thoughts: Its big! Darn big. Make sure you have the room to install this. I have this installed on an ASUS P6T V2 in a Cooler Master Storm Scout case and I have less than an inch from the side window to the top of this fan. This has made it impossible to install the second fan on the window, but thats not a problem since I have enough cooling and I was able to install the first fan on the window (the window has places for 2 fans set vertically). I also was able to install both fans on this cooler since I had the room. If you want to use both fans, again, make sure you have the room. The other thing that I want to point out is that the fans that come with this cooler are beige and brown. Kinda an ugly choice of colors considering all the colors in the spectrum to choose from. If you dont like the fans that come with it, you can always buy other fans but it isnt really necessary. All in all, this is a great cooler.

Pros: works as advertised - keeps my overclocked 965EE from melting and does it quietly.

Cons: CPU still runs hotter than i had expected (near 80C under heavy load at 4G), but i reallize air flow and ambient room temperature is probably more the cause for this, but at 10-20C higher than benchmarks and reviews is still dissapointing: -1 egg.

Other Thoughts: i bought this product based on the many reviews that i read about it. i had an expectation based on those reviews, and it did not (quite) meet those expectations. but, it is still an excellent product.

Pros: I was immediately blown away by the build quality of these components as I took them out of the box. These days there are so many corners cut in production, and it's so great to see companies that break that mold and craft a truly fine product.

As far as the performance goes, I couldn't be happier. This thing is extremely quiet and keeps my processor extremely cool. I don't even think it's necessary to have both fans attached to the heatsink unless you're planning on overclocking.

Cons: The only thing I can really think of is that it comes with a lot of pieces, and can possibly be a little confusing to put it together and mount it. I didn't really have any issues. Fortunately it comes with great instructions that illustrate the whole process.

Other Thoughts: Last time I built a PC was several years ago before Noctua was even around, so I've never used their products before, and never heard of them until just the other day. Boy do they have me sold. I will definitely be using their products in other projects down the road. Noctua obviously goes the extra mile to give their customers a fine product. They even included a screwdriver.
