COOLER MASTER Hyper 212 Plus, Great Cooling abilities and a VERY reasonable price, some people say its quiet, some say its ok, few people say its too loud for thier liking. Its really up to the user to make their own opinion I guess.
I recommend this cooler to everyone, its amazing and its only 30 dollars on newegg.com with a 15 dollar mail in rebate.
For the people who say it loud, get over it, you can replace the fan with a better one, and even then its still cheaper then most of the garbage 70+ dollar heat sinks.
This is the best cooler for the money.
