Silent but deadly

Pros: Quiet - I can't even hear it at full speed in my case about 2 feet away
Cooling power is exceptional
Great compatibility with ram and case
Fantastic fit and finish
Replaceable fans - this is a fairly standard feature, but it means the heatsink can be reused for many years if the included one fails.
A lot of time was put into making this foolproof - the design is fantastic from a simplicity of installation perspective and consistency of performance. Spring force is used to hold the cooler onto the processor, ensuring a consistent mounting pressure.

Cons: A bit pricey - not a huge issue if you reuse it many times. The heatsink will absolutely outlast the included fan, which is replaceable.
Engaging the screws into the retention mechanism took a little work and a little more force than I was comfortable with

Overall Review: This thing is hot, but my processor isn't! Highly recommended for a Ryzen 3rd Gen processor.

Mine came with a standard AM3/AM4 mounting bracket, so the specialized SE-AM4 version isn't a must for a new AMD processor.

One of the best

Pros: Bought this to replace a silver stone cooler and instantly shaved off about 20c on full load! Was torn between this cooler and the arctic freeze 34. I simply chose this one because of the contact to the heatsink has a zinc plated copper block soldered to the heat pipes and the arctic cooler does not. Sure this one was twice the price as the arctic but I was looking for quality not economy. And I don’t regret it. The fan is a 4 pin connection and ships with a low noise adapter which I’ll never use. This putsout plenty of air on a single fan set up. But I bought an additional fan to put on the backside and I don’t regret that one bit either. This is hands down the best cooler for an lga 115x

Cons: None

Works Great!

Pros: Works great
Good price
Came with the thermal compound so I didn't need to buy any

Cons: Not very good looking

Overall Review: It's not a very pretty looking cooler but it really works very well! I don't have a setup that shows off the components inside the case, so looks do not matter.

Overall Review: Would recommend.

Noctua delivers once more

Pros: - Quiet
- Compatible
- Well packaged
- Good performance

Overall Review: I was about to buy a second one of these units so I figured I may as well write a review in case anyone is still on the fence. I won't spend time comparing this against other specific models from non-Noctua companies. There are more serious reviews for that.

Here's what you get by spending a tiny bit more on a premier unit from Noctua: Reliability, comfort (noise), performance, high quality vendor support (motherboard compatibility sheets, customer support, free parts (brackets!) sent to your home in certain situations).

In particular the NH-U12S has high compatibility with tall memory heat spreaders, VRM heat spreaders that are close to the CPU, etc. It uses a modest sized fan so that it can fit in smaller cases. It's quiet and you can tune that by using different fan speed.

The install is well documented and does not require any awkward movements to be made.

Quiet CPU cooler!

Pros: Very quiet, especially compared to the stock Intel LGA fan.

Cons: Be sure you know you have to remove the motherboard to install the bracket underneath the CPU. Also be aware it is tall and may not clear your case.

Overall Review: A great cooler - runs a few degrees cooler than the stock Intel cooler. Also almost totally quiet. Recommended!

Keeps the Ryzen 5 cool

Overall Review: Keeps the Ryzen 5 3600 cool. 29°C at idle and 68°C at 100% load in my ancient Antec Nine Hundred case.

I don't think the 140mm or the 150mm version would fit in the case.
