Well, I give it 2 stars because...

To install it on AM4, specifically on the AMD Ryzen 5 2600x that I have, there is no manual, and there is no help on the internet because the brand is Chinese.

You have to put the plastic pieces that were on the motherboard, and then connect the cooler on top of those plastics with its clips. The bracket inside the box is useless for AMD, it is probably for Intel sockets. But nowhere on the box did it say anything.

Also... the stock cooler from AMD Ryzen is better because under full load, this particular one... reaches 95 degrees while the stock one reached 80, come on, I know it's cheap but just because it has lights doesn't mean it has to be so bad, at least it should be the same as the stock one from Ryzen and I would say it's fine, at least it has lights...
