What CPU Cooler Should I Get for a Ryzen 5 3600 in a Hot Climate?

I'm using an AMD Ryzen 5 3600 with the stock cooler on an ASUS Prime B450M-K II motherboard, but my temperatures are extremely high and the system sometimes shuts down because of overheating. I live somewhere with a very hot climate, even during winter, so I'm looking for an affordable replacement cooler. What would be a good budget option?

The Thermalright Phantom Spirit 120 is a common recommendation because it performs very well for the price, but its dual-tower design may be more cooler than you need. If local taxes make it too expensive, look for any affordable Thermalright single-tower cooler with a 120 mm fan. It should still be a major improvement over the stock cooler.

MellowOrbit7: The Phantom Spirit ends up costing about a third of my monthly wage after taxes, so I need something considerably cheaper.

Before buying anything, make sure the stock cooler is clean and properly mounted, then replace the thermal paste if itโ€™s old. Adding at least one inexpensive intake fan can also improve airflow through the case. The Ryzen 5 3600 normally shouldnโ€™t overheat badly with its stock cooler, so shutdowns could point to a mounting, airflow, or fan problem.

MellowOrbit7: I repasted it yesterday and only gained about 4ยฐC. The room is extremely hot where I live, and the computer still sometimes shuts down from the temperature.

MellowOrbit7: The case fans spin, but I barely feel any air coming from the intake or exhaust. I may need to check whether theyโ€™re actually moving enough air.

The Thermalright Assassin X 120 Refined SE is a sensible budget choice for the Ryzen 5 3600. Itโ€™s compatible with your AM4 motherboard, offers much better cooling than the included cooler, and shouldnโ€™t be excessive for this processor. Just confirm that your case has enough height clearance before ordering.
