Weird Crackling noise from new PC if using 4.4 turbo

mardi 3 mars 2015

Ok ao i just built a killer new PC



Here are the Specs

5820k Intel

X99x killer mobo

850pro SSD

1tb WD spare drive

gtx980 GFX card

16g Ram ddr4

34inch LG Ultra Wide Monitor "debating to return for Dells 34inch curved"





Anyways i havent overclocked much in my recent PCs but always dabble with it. WIth this X99x MOBO i used the bios overclock for the ram and adjusted my turbo settings to 4.0 then to 4.2 and yesterday 4.4. Played all games ran 3d mark and scored very high.



Here is my issue. I noticed a crackling noise that was coming from my PC, it sounded like a HD cycling. I figured it was my WD tb drive since a SSD has no moving parts. Thing is it was always making this noise even at idle and was starting to annoy me. I tried unplugging that drive yet still heard that noise... So it dawned on me the only thing that i had changed was the turbo speed from 4.2 to 4.4. So i went back into the bios and put back to the 4.2 and to my surprise that crackling noise has stopped...



Any idea what was taking place here? Isnt just changing the turbo speeds increasing the core speeds when its needed in a game or application? Why would it make this noise at idle doing nothing?



If i wanted to go back to the 4.4 what could i do to stop that noise? Could it be low voltage? and what part of the PC is actually making that noise?
