After watching your video, I noted a few things that I feel would definitely help to improve your PC and make it more efficient and quieter. My first recommendation is to get a better system of cable management in the case. This will allow you to turn your fans down and lower the volume. Also, if you want, you could hook up a water cooling kit but this is pricey and not the best option. If necessary, buy some better fans that are lower vibration and will be quieter and more efficient when they run. I hope this helps and good luck!
