is there something wrong with it or am i over worrying?
i know the sound is coming from the top left corner if you are looking from in the case
i also dont know which ventilator it is because it came with my pc
other pc specs: AMD FX 8320 with CoolerMaster 212X CPU
2 x 8 GB RAM
GTX 970 4GB GPU
VS 550 PSU
Motherboard: Gigabyte 990FXA-UD3

Should i clean it up with compressed air spray or even oil it?

Thanks in advance.
