Needed a replacement for the stock Intel as i find the buzzing it makes at around 70C distracting.
After a day researching it seems this make was the Rolls Royce of fans. I was thinking do i really need such a fan, i dont even overclock, but in the end i got it and havent regretted it.

I laughed at the size of the fan when i unboxed it. I handed it to my dad who thought it was a radiator for a motorbike lol. I have a full sized case and the side cover goes on with about 1-2mm spare.

I was very surprised with the amount of stuff that comes with the fan.

-AMD and two Intel mounting kits (intel 2011 and 1155/6)
-Screw driver
-Thermal paste
-2nd fan installation kit + instruction on how to install the bigger 14" fans.
-Low noise adaptor (though i dont know why, its dead silent with out it)
-Thick metal Noctua badge to go on the PC case

Installed it without to much effort. Had to remove the motherboard even though the case has a gap at the back specifically so you dont have to. It was 1mm to small...

I'v never heard it operating so far, its completely silent. Highest temp its gone is 60C with was playing battlefield 3, even then the fan was pretty much idealing.

Strongly recommended item if ur looking for a silent rig. Only thing i didn't like is the colour... Its sorta their trade mark now, but maybe time to update? lol.

5.0 out of 5 stars Noctua NH-U12S, Just Buy It!! 13 Jun 2013
Verified Purchase
This is a top notch product, installed into a averagely noisy computer and has made it virtually silent (you obviously still get the noise of air passing through the fan), I am now sat in front of my TV writing this review in complete silence (computer in cabinet under TV) which is bliss after the high pitched whine of the AMD stock cooler.

Running a video programme with stock cooler (Came with FX 8350 8-core 4.0 GHz CPU) had these readings
Speccy 63c
Asus Fan Xpert 71c @ 100% fan speed (also had Temp and Voltage alerts)

With Noctua NH-U12S
Speccy 43c
Asus Fan Xpert 57c @ 87% fan speed

No discernible noise where as the stock cooler at this point sounded like Concord taking off lol

Even my graphics card (non fan type) is running cooler, I am so happy with this CPU Cooler, can honestly say it is one of the few things I have ever purchased and been 100% happy with it.

5.0 out of 5 stars Forget about hydra cooling ~ buy Noctua 2 Jan 2014
By Terence
Verified Purchase
Seems stupid to say it now, but I didn't buy this product right off the bat because, well, I didn't like the way it looked ~ kinda retro. So I fooled around with a couple of Corsair liquid cooling systems. What a big mistake that was ~ parts that didn't fit, software that was buggy and in the end a fan controller that decided to go AWOL and leave the fans screaming at maximum all the time. How much simpler was to install and how well made, if a little quirky, is this Noctua unit... but oh, how much quieter. Not only that but it dutifully takes its orders from the Asus Fan Expert 2 software without a murmur. And speaking of murmurs, as I write this I literally can't hear it running to the point I just had to go check if it was still working. It looks like an awesome piece of kit and it comes with a six year warranty ~ you can't beat that. Do yourself a favour ~ get one. They're the Rolls Royce of the computer fan industry, sturdy, well made, and do what they are supposed to. I couldn't be more happy with my purchase.

5.0 out of 5 stars Awesome 1 Dec 2013
Verified Purchase
The Noctua NH-U12S is a brilliant cooler for modern CPU, along with High Profile ram. The compatibility is guaranteed, and I can confirm that with my Corsair Vengeance I don't have any problem.
The temperature of my i7-4770k is incredibly low, about 25 in idle. The fan is absolutely silent, and I'm using it without the included adaptor that reduces the maximum fan speed to get less noise.
It's not cheap, but you pay for the quality, and Noctua is probably the best out here about CPU coolers.

5.0 out of 5 stars Almost silent for most tasks. 22 July 2014
By simon

Installed onto Asus Z87 pro motherboard on a i7 4770 in a Corsair 300R case.The cooler just fits into the case with about 1cm clearance.The TX650 power supply fan does not operate in my rig due to low power consumption (I don't have a graphics card) .

The stats:

Room temp 24 degrees Celsius .Motherboard temperature 35 degrees

Intel stock cooler idle temp 35 ,under prime95 load test 82 degrees..Fan speed idle 1090 rpm ,load 1950 rpm.

NH-U12S cooler idle temp 31 degrees,under prime95 load test 58 degrees.Fan speed idle 618 rpm (can go as low as 250 rpm under Asus fan expert settings but the idle temp goes up to about 35 degrees), load 850 rpm.

At idle the Noctua is very quiet,in fact from a meter away from the case it can not be discerned from the case fans which are running at about 480 rpm.However at 1500 rpm the Noctua is fairly loud , almost as loud as the case fans running at about 900 rpm.

Overall the NH-U12S is very much quieter than the Intel stock fan for most applications.However I noticed a slight clicking sound when I placed my ear near the vents in the 300R case.

5.0 out of 5 stars Best cooler ever! 16 July 2014
Verified Purchase
Well this CPU cooler for me is just the best! I cannot recommend it enough! The reason is because I've chosen before this a liquid cooling which was corsair h80i which as a few other said it, the pump can start playing up after 3 months which is exactly what happened to me too! All of a sudden my pump on corsair started doing some funny noises and the temperatures jump in idle from 40 celsius to over 70 nearly to 80 which is a lot!!! So after reading some reviews online I found out that you cannot do much about the pump or its speed as this is apparently the cause of this noise and its poor performance!!!! So I decided to buy this amazing cooler which performs a lot better than the corsair h80i even under load test!!! Where the corsair h80i was keeping my CPU at @ 65 to 70 celsius under full load this keep's it at @ 52 to 53 celsius which is far mor better plus that this has no parts that can go wrong at any time!!! Plus the very well building feel and look of this cooler is just outstanding!
I hope that my review helps you make a wise decision!!! (Not like me in first place!)
