If cost and ease of installation are your main considerations, an air cooler is probably the best option. The Cooler Master is a good option over a $40 cooling solution that outperforms stock cooling without breaking the bank. Being quiet is one of the options for air coolers on the market. On the other hand, a water-based cooler is probably for you if you want a quieter PC with lower CPU temps. Simply budget for additional money. A high-end AIO will outperform most air coolers on the market with a 280mm or 360mm radiator.
