Glad I found this one to use. It is quiet and lightweight.
Bought two of these. Was surprised that it fit in a micro Coolermaster N200 case. Have a bit of room to close the lid. It is a little tricky to get the hooks on but surprised that it keeps a Ryzen 9600 cpu very cool. I love the copper piping. Isn't very heavy either. Worked great on the two computers I built recently.

Great cooler
Easy to install, looks good, runs quiet and keeps the chip cooled

A solid 5 star CPU cooler
I put this on an 5900XT (16 cores, 32 threads). It runs cool, it's quiet, well made, and it looks nice. Temps have never gotten close to throttling levels so far. It's far more reasonably priced than water coolers. Mounting wasn't difficult, but you need to change the motherboard fan mounts. Examine the instructions carefully as the mounting brackets are not interchangable, and need to be in a specific orientation. Be aware the heat pipes extend out over the RAM, and there may be clearance issues with some RAM modules. It's also pretty large, and it may not fit in smaller cases.

I'm surprised
I just paired this with a Ryzen 9 5900X, I had some doubts that it may not be enough since people in the reviews for the 5900X went on about needing either a monstrosity of an air cooler that takes up a ton of room or a massive water cooler to keep it cooled properly (how far are you guys overclocking this thing??), even after reading into these coolers and their website rating it for Ryzen 9 at 195W TDP. Well, my doubts were put to rest, it idles in the low to mid 40C range and running a stress test and watching it while I was working in ASUS Armory Crate today after installing, the highest I had seen was mid 70C range and I had ran through some more of the demanding stuff to see what it would do, no throttling, no warnings, no blue screens, no problem. I am also not overclocking it and have no intention to do so. It was also pretty easy to install as long as you follow the directions, everything was metal aside from the spacers that fit onto the screws for the AMD mounting bracket. This cooler isn't small either, I have a wider Zalman case and it is just tall enough to where it fits without impeding the glass side cover, but any further I wouldn't be able to get the side cover on, so make sure it will fit your case (my last case on an older machine I had to cut a hole in the cover to fit a larger cooler, bummer). The good thing is that it doesn't block the RAM sockets or anything else on my B550 Plus. I did not want to get a water cooler, and I'm glad this worked out and I'll probably buy more of their products in the future. You may also want to consider buying thermal paste with it, when I got mine it said it was already applied but it was not and thankfully I had some in my desk drawer (I had a tube of Corsair TM30), and I did see some reviews of apparent mishandling of the packaging that caused it to shift and smear paste all over inside the box.

Solid option.
I bought this to replace an Arctic Freezer 34 eSports cooler I thought I was having trouble with. It turned out to be a different issue all together, so I put that cooler in another system (same CPU, GPU, cases and fans) and run them side by side. Most of this review will be a comparison of these two coolers. What I find most surprising is that the Arctic is quieter. The Pure Rock isn't obtrusive or by any means loud, but you can't hear the Arctic over the GPU fans when the systems are under load. You can hear the Pure Rock. The Pure Rock's mount covers the entire heat spreader (5600X), the Arctic's does not.. but there is no real difference in CPU temperatures under load. Both coolers keep the CPU at about 31 C idling and running a stress test I see maybe 64 C. The Pure Rock does seem to ramp up more slowly, but the difference is pretty minor. I prefer the mounting system on the Arctic, although both are quite solid. The fan clips are more secure on the Arctic. Overall the Pure Rock 2 is a very good cooler for the money, and the two I'm discussing here are for all intents and purposes interchangeable. The Pure Rock's cooler assembly seems to be of slightly higher quality, with it's added heat block and the caps on the heat pipes. All of the mounting components, both the motherboard mount and the fan retention clips are easier to use on the Arctic, and the fan retention clips are far and away more secure on the Arctic as well. At the same price point I'd choose the Arctic.

Works on My Machine.
Nice and Cool and Quiet as the name implies! I don't understand all the reviews stating it has no AM4 mounting works with mine!

Perfectly easy to set up. Bit huge and wouldn't fit with my RAM. but it's detachable and "move around-able" fans fixed that in a hurry. 4 Stars easily.

Cooling my Ryzen 5700X with this and it does a great job. Rarely over 70C when I play games, and also very quiet. A fitting upgrade to the Wraith Prism I used before, which was both loud and had my CPU creeping up towards 80C in some cases.

The be quiet! Pure Rock 3 LX CPU Air Cooler is solid and quiet. I am using it for a Ryzen with 65W TDP and it keeps it nice and cool. Great value.

You want quiet? Buy it. It doesn't get quieter than what you get here. Very recommended.
