Question CPU Clicking noise at high speed.

Hey, I'm not an expert on pc components and thus I came across this website seeking help.

Problem is that my CPU fan starts to make extremely annoying clicking sound whenever it's at full speed. (Not always but sometimes) Especially whenever I turn on the PC. It usually goes away whenever I manually reduce the speed of the fans.
I'm also currently monitoring my temp for CPU lately and I noticed my temp is never stable during idle mode. I don't know if it's my pc or the program itself, it doesn't seem right since it quite literally changes every sec. (Jumping between 35-50c every sec)
I'm using Intel i7- 4790k and also XMP profile if that says anything.
I was also thinking maybe it's due to my wrong placement for the CPU fans. I post some pics here.
