What customers say about "Key Specs"

be quiet! Dark Rock Pro 4 CPU Cooler

Quiet operation and good cooling performance.
The Dark Rock Pro 4 is a massive cooler and it does a wonderful job cooling intel’s i9 9900k.
I installed an intel i9-9900k and its definitely keeping it cool.
I love this cooler. It's delightfully quiet, looks great, and performs as well as you'd hope it would given the price tag.
Superior cooling performance. Highly recommend.

Noctua NH-D15 Premium CPU Cooler

If you're not going with water cooling this is your best choice. This product beats out most of the entry level water cooling options and performs really close to the top end ones.
Keeps CPU extremely cool.
I'm actually a bit surprised but Noctua has convinced me. I don't often use Air coolers for builds anymore but if and when I need to I know that Noctua does make high performing products.
Best, most effective air-cooled heat sink I've ever owned. Don't even need the second fan that's included, I'm under 60 degrees C at full load at my max overclock.
With good airflow, this will allow you to overclock without worrying about cooling.

What customers say about "Size & Weight"

be quiet! Dark Rock Pro 4 CPU Cooler

Looks good for the size. Very quiet fans.
This is a monster size air cooler. Doesn't have any issue about size or weight.
Make sure to have enough space for your ram and the case itself. It's huge size.
The install and size are the only cons.
The size of this CPU cooler can interfere with RAM and it makes it kind of difficult to work with when working inside the case.

Noctua NH-D15 Premium CPU Cooler

Installation is easy considering the size.
It does a nice job of cooling but it's huge. It blocks access to the memory modules on my motherboard.
Be prepared for the size of it and make sure it will fit in your case.
Only major complain is the size it's huge and a pain to put on and still interferes with ram space.
Be careful with the size of this monster. It is HUGE. If you have a large computer case, this shouldn't be a problem at all. The size of the cooler helps with its performance.

What customers say about "Features"

be quiet! Dark Rock Pro 4 CPU Cooler

This cooler is made of very sturdy and quality material.
Its fans help to cool the rest of the components to boot. It is large. It is very quiet under load.
Keeps things cool with low noise output.
This keeps my cpu very cool and very happy. Installation was fairly painless.
The mounting brackets fit into the cooling fins a little too tightly.

Noctua NH-D15 Premium CPU Cooler

Even at 100% fan speed, they are not very loud.
Slightly puzzled by the inclusion of the speed reduction adapters, as even at full speed, these fans are completely silent.
This fan is quieter at full speed than my stock CPU cooler was at it's slowest.
It's about the same as the noise floor in a normal room.
A long way from the scary temperatures I was getting prior to the new cooler. I cant imagine this cooler getting hot ever!
