i completed building my gaming pc today which has a 6700K as a proccesor, a cs650m as a power supply, a gtx 1070 gaming x as a graphics card and a cooler master hyper 212 evo for cooling the cpu. Everytime i start it up the there is no sign of an annoying sound but after few minutes it starts to make the most annoying noise in ever. I have noticed that when i hit my table for its stops for 30 secs or so then starts again. I can't locate where it is coming from but im pretty sure it not coming from the gpu since the fans start turning when the pc hits 40 degrees. Please Help 🙁
