I've never had a CPU cooler a quiet as this one, and I simply cannot overheat my CPU anymore!
As I write this, the cooler is 4 feet from my head beside the desk, and I cannot hear it above a very gentle breeze outside.
Do be warned: the heatsink/fan combo is BIG, needs a large case, and can interfere with RAM access depending on the MoBo.
I am unable to remove/replace my RAM without removing this cooler, and I imagine it could interfere completely with the RAM slots on some MoBos.
Check the dimensions carefully, and be sure your computer case is large enough!

I bought this because my computer was running very loudly and as far as I could tell, it was the CPU fan.

After pulling the old fan off and putting this one on, the difference in noise was tremendous. I can't hear anything running now and haven't had any overheating issues at all.

Noctua reminds me of those expensive restaurants, where you expect to pay a leg and arm and only get a "mini-meal", but you actually get a really good meal that leaves you full and makes you forget how much you actually paid.

Weird analogy? Check.

This is my first after market HSF, I wanted something that was better than the stock AMD HFS, but at the same time not as loud. Noctua delivers. I'll make it quick:

- It cools. I noticed a a 7-10C drop.
- Quality, just by seeing the packaging and actually touching the product you know you got what you paid for.
- Near-silent. The fans are only 3-pin, not PWM. In reality you don't need the motherboard to control the fan(s) speed. Why? You can barely hear them. And if you do, you can use the adapters that come with the HFS to lower the RPM and the noise. I used the Low-Noise adapter and saw minimal changes in the overalll temperature.

Cons:

- You might be able to find a cooling solution with a smaller footprint, but perhaps not with the same quality and/or performance.
- If you have AMD, you'll have to set up the fan(s) to draw air from the bottom of your case to the top. While this works, most people prefer to have it the "standard way" which is drawing air from the front to the back.*

Other toughs:
- *You can order this Noctua NM-A90 Upgrade-Kit for NH-U12P SE2 and NH-U9B SE2 CPU coolers to set up the fans the other way.
- I got the free kit from Noctua. I taught that would help my CPU, but in fact added about 1-3C to the temperature. I changed back to the original orientation.
- If you're thinking "these are not as quiet as everyone else is saying", please check your other components, most likely your GPU, or case fans are louder than the Noctua fans.
- Colors, weird but not as bad as in the pictures.

Installed very easily on my motherboard. Clear, well-written instructions for installation of the heatsink. The heatsink itself just *feels* very solid and well made. I did have to move my RAM over to the next available matching slots to make room for the dual fan clips, but that wasn't a very big deal. As far as results go, very happy with those. Idle temps dropped immediately by about 10 degrees celsius (hovers around 39-40c on my system). While gaming the temps dropped a whopping 20 degrees! It was getting up near 70 degrees, but now comfortably hovers in the upper 40s.

One thing I didn't like was that I had to mount the fans on the top and bottom when I would have preferred to have the air flow going horizontally, but it wasn't a huge deal. Very happy with the product overall, and very reasonably priced!

Put a new motherboard and 6 core amd cpu into my main computer used for video editing, serviio, games, programming and general web browsing, etc. The cpu fan that came with the cpu looked very undersized and was noisy so I installed the original cpu fan that had been OK in the old motherboard but still a little noisy at times. This older fan was copper heat sink and a much larger size that the fan that came with the cpu. It was quiet until the cpu ramped up on 6 cores at 100% during encoding videos or other cpu intensive operations. cpu temps were good but the noise from the fan was loud. After encoding the noise level went down but occasionally got loud probably due to serviio or some other process.
Did not like the idea of pulling the motherboard back out to install this fan but wanted a quieter computer. Installation instructions and design was very good. Quality of components was excellent. This computer has never been this quiet. I also later upgraded the 120mm case fan to Noctua and that made it even more quiet but not the level of improvement that this Noctua cpu fan made. I would highly recommend this to any builders or those who have noisy cpu fans and want a quieter computer.

It's amazingly quiet with the ultra low noise adapters and it keeps everything cool. I'm not sure why, but for some reason the RPM of the fans don't change. I think this is because the fans aren't PWM but it's okay. At full load, it doesn't go over 60C which is great!!! Note that this is with my i5-4570k @ 3.9 GHz. I'm not using this to overclock or anything but for pure silence.

If you're too lazy to read:
Pros: Quiet
Keeps it cool.
Comes with ultra low noise adapters, they're actually effective. (3 pin only)
Also, comes with a 3 pin splitter making you able to connect both fans to one 3 pin connector.

Cons: A bit big.
No PWM fans, this might be a problem to people that prefer higher RPMs when things get hotter.
