Since installing a new GA-990FXA-UD3 mobo + AMD FX-8350 CPU my system makes a seemingly random soft, popping sound. It's coming from the case and not the speakers (I hear it with the speakers turned off and the headphones unplugged) and I've only heard it since the upgrade. The system works fine and I've had no problems. I'm just curious what's causing the popping sound.
System specs:
Gigabyte GA-990FXA-UD3
AMD FX-8350 Black Edition Vishera 8-core
2 x Crucial Ballistix Tactical Tracer 4GB DDR3 1866
Seagate ST3 1T SATA

Cooler Master Seidon 120M Liquid Water Cooling
850w PSU
