Pros: Was looking for something that would cool my new i7-6700k skylake and fit in my nmedia 6000b case with low noise as I have this in my livingroom audio rack. Fits well, paired with the gigabyte G1 mobo as part of a combo deal this thing just barely has clearance to not block any ram slots. Can't really do much overclocking with it, but keeps the stock settings for my skylake around 30 degrees Celcius under normal load conditions, up to about 51 under heavy load.
Nice an quiet too!

Cons: None

Other Thoughts: This was my first noctua purchase. I am very happy with the quality, quietness and the compactness of this unit.

Pros: Keeps my CPU very cool and is crazy quiet.

Cons: It is pretty large and i had a little bit of an issue with my mini itx ram slots and cpu power supply.

Other Thoughts: i love it and would buy more and recommend

Pros: I used this in a 17 year old In-Win A500 mid-tower computer case with the top fan removed. It fit nicely and is very quiet on an AMD triple core Athlon CPU.

Cons: None

Pros: Keeps rig nice and cool. I had one previously on a different set up and it performs very well. Kept it mostly under 47C even on high loads. Very happy with the company.

Cons: Colors. Could use some customability to match colors of setups. =/

Pros: Versatile, compact, quiet, high performing, multiple configurations, easy to install, high quality, lots of extra accessories, including a screwdriver. Downward fan helps to cool vrm's. Very very high quality fans.

Cons: It might block a ram slot, depending on your motherboard and overall configuration. Price is a bit high unless on sale.

Other Thoughts: This is a case of "you get what you pay for." It costs a lot, but it is basically the best product on the market in this specific category.

Pros: Fit my mini-ITX ASRock mobo perfect

Cons: Broke two fins of the large fan on top. Heat piping is cheap and easily bendable. All parts seem cheap & flimsy. Had to purchase new top fan at a local computer store. Went with something sturdier

Pros: Very quiet and keeps my CPU cool. This thing get a lot of weird looks seeing how its flat on the CPU instead of being on its side like most aftermarket coolers, but its a beast. I bought it for a mid-tower case and it fits great, works great. Would buy for another system in a heartbeat.

Cons: Had some RAM clearance issues for a bit, but I'll chalk that up to my MOBO layout.

Other Thoughts: I know its Noctua's thing to have the brown scheme, but I dig it. More of a statement than a clash of colors.

Pros: Very high quality parts and slick packaging. Super quiet.

Cons: None. Minor comment; you are paying a lot for the box.

Other Thoughts: Installed after replacing lesser quality coolers for my 17 Photoshop machine. You get what you pay for in this department and Noctua delivers a solid product.

Pros: This thing is perfect. It isn't too large but is still a major improvement over the stock cooler. It's a Noctua, high quality, performance, and easy installation is what this thing is about. It is easier than the stock intel cooler to install. Did I mention quiet? It is. Don't wait any longer. If you are thinking about this over another cheaper average cooler as an alternative to the stock cooler, buy this.

Cons: None. If you do your homework, make sure this fits in your case / on your mobo. Had only one option to install this without blocking my mini ATX boards PCIE slot and the other was hitting my ram.

Other Thoughts: This is the first Noctua product I have purchased and I'm never recommending another over it (Unless someone literally can't afford it). Worth the money.

Pros: Easy to install. Silent. Very efficient cooling kit. Excellent design and awesome quality package. Noctua is Noctua, what can you expect more?

Cons: One thing, color needs to be changed but it is its trademark. You know it's a Noctua when you see the beige-brown fans.
