Intel coolers are not good. They work to keep the CPU from dying, but you will need to increase your cooling capacity with an aftermarket cooler if you want to get your temps down and performance up. The basic recommendation for the longest time is the Cooler Master Hyper 212 Evo. It has been working great for years for tens of thousands of people. Bigger/better wouldnt hurt though. A bigger CPU cooler has no downsides besides cost and size. An overkill CPU cooler, like I use, will just run cooler and quieter than normal.out of the box cooler
