The most value for money purchase I have made. The 5600 stays below 58 degrees Celsius even in cinebench and the fan never needs to increase its speed, so it is almost silent.

It fit easily into the Asrock B550m PG Riptide motherboard, which supports the AM4 chipset. By removing the stock cooler, you will need the back plate where the screws are attached. I easily screwed the 2 metal brackets onto the cooler and then applied the cooler and screwed it onto the motherboard. The classic rules apply, meaning you screw gradually and diagonally, etc., because the screws have washers, there are videos on YouTube from other coolers, practically the same. It lowered my temperatures by 10 degrees Celsius at idle and the same on-load, maybe even more. I did a stress test (Cinebench) with precision boost overdrive enabled, it went up to 65 degrees Celsius, obviously higher than optimal temperature. My CPU is the Ryzen 5 5600. That's it, the price is excellent at 21 euros, and the quality as well. It should be noted that although it came with a syringe of thermal paste, I used my own, Arctic MX4. Finally, it claimed to include a small brush for the paste, but it was not there, luckily it is unnecessary, just a simple luxury.

Plays on a Ryzen 5 5600. With the stock cooler with open PBO, I saw something around 90+ degrees in rendering and decided to install this one to improve the situation a bit. With MX4 paste, we have different idle temperatures ranging from 47-50 degrees, it went down to 33 degrees, and in Cinebench R23, it went from 90+ to around 55 degrees (room temperature around 20 degrees and Corsair Graphite 230T case). The build quality is average but normal for its price, it is quiet, and overall it is definitely worth its money. Also, its height is not exactly 155mm but somewhere around 150-151mm.
