While in the description it says am3+, the box says am4 am5 and its base is am4 am5, so it does NOT fit in am3+. And while it says it has 4 pins, it actually has 3 pins, resulting in it not fitting in my computer

Although I was afraid of it for its price, I can say that it is quite commendable and of good quality.
It was used on the Q8400, with the stock cooler reaching temperatures of 61° to 69°-71° degrees. With this one, the temperature is consistently at 45° and at peak it reached 51°.
The installation is very easy and simple.
The colors it has in RGB look very nice and in no way does it reflect its price. A very good and commendable choice.

I have used it on 3 systems, very good for its price, superior to the stock and RGB. It is a lightweight cooler for processors up to 70 W. I5 2500 at 3.7 GHz, 28°C external. With stock cooler, idle at 40°C, full load at 74°C. Jonsbo CR-1200, idle at 36°C, full load at 64°C

I put it on my processor (Ryzen 5 3600) and I have one thing to say... By far the worst cooler on earth. I would have been better off putting ice cubes on the CPU, they would have done a better job. Just imagine opening windows and reaching 80 degrees. Sometimes it even gives me a blue screen before the windows even open. Stay away..
