I believe is the CPU fan or GPU, but I am not sure, will probably post a video tomorrow.

Was also thinking about getting a Fractal Design S

Sorry if it's the wrong section but didn't know where to ask besides "system" but most people just ask for builds there.
 
open the case...with the pc off unplug the cpu fan...you get a bios warning just go into the bios see if the sound goes down...if not power off and plug the fan back in then unplug one of the case fans. then the next case fan. if the fan sound still there pull the gpu and use onboard video or use msi afterburner to turn the fan up/down to see if it the gpu. if it not the gpu use a 3 party program to turn the power supply fan on/off.
