Liquid loops are extremely silent, and you do not need to worry about their noise. If you have a lot of fans operating at high speeds, then your CPU will be all fine. But, your computer will sound like a jet engine.

You can avoid this by choosing a larger and quiet fan. Many latest models have automatic fan stop technology that shuts them off when not in use. Now, most gamers mostly use headphones which means that noise is not a significant issue.

7. RGB

RGB stands for “RED-Green-Blue”. These are LED lighting that can create millions of colors by mixing various primary colors. RGB fans let you personalize your case to add some personality. You can make amazing light sequences with RGB synchronization which makes gaming high intense and thrilling.

8. Overclocking
