PROS:
The build quality is very good and installation is fairly easy. It also has an AM4 offset position option. At full speed, the fan can't be heard in my sound-dampened case. It also has no RAM clearance issues, since it has a slim profile.
CONS:
Its performance is only slightly better than a stock cooler, at least for Ryzen. With a 5700X at stock settings and a room temperature of 23°C, under 100% load (SVT-AV1 encoding), the processor reaches 80°C, while the CPU package in HWInfo reaches a maximum of 132W. This is with Curve Optimizer at -20. So forget the theoretical TDP the company lists (190W), unless you live in Lapland. In my PC, with a room temperature of 30°C, that means it would hit 87°C. Of course, I have a case designed for quiet operation (BeQuiet Pure Base 600). If you use it in a case that sounds like an airplane, it may perform better. In summer, I set its PPT to 88W and everything is fine. For the same or less money, there's the Arctic Freezer 36, which is a better cooler. For my case and Greek summers, the Pure Rock 3 has a realistic limit of 140W (around that point it'll hit 90°C, which is TJMax for Ryzen). For the reasons above, 3 stars.

I have been using this particular cooler for about 4 months now and I am really very satisfied with my purchase. I got it mainly because I wanted to replace the Intel stock cooler, because as is well known, they sound like airplanes from the noise, especially when the processor is under a bit of load.

From the moment I installed this cooler, the difference was huge, mainly in terms of noise. It is really very quiet and that was the main thing I wanted from my purchase. Even after hours of gaming or general use, the PC remains quiet and much more pleasant to use.

Temperatures are also very good and normal for an air cooler of this category, without facing any issues. Of course, we're not talking about anything extreme, but for everyday use, gaming, and generally a normal setup, it does exactly what it should.

For its price, I think it is very much worth it and is many levels above the stock coolers usually provided with processors, especially Intel's. The difference in noise and overall user experience is huge.

Overall, for me, it was a very good and honest purchase. If someone wants an affordable, quiet, and reliable cooler without spending a lot of money, I think it is definitely worth it
