**UPDATE**
I opened up my side panel and it is the pump making the high pitched buzzing/whirring sound. I have the EK-XRES 140 with D5 pump (pump/res combo) there is definitely enough water and it is gravity fed so I'm not sure what the issue is. It is a molex and pwm controlled pump so this noise only occurs under loads. (It is plugged into one of the fan headers on the mobo and the molex into the PSU)

Well I've been running furmark for a while and that noise is definitely going down. Thanks
