[QUOTE="jasongoldworthy, post: 1824510, member: 395464"] hi there, I have just listened to the video with my headphones on and the fizz/buzz isn't normal one way to tell if its the fan is to temporarily stop the PSU fan with your finger obviously it will ramp up when you let it go. but will then settle down, noises from the PSU are never good in any form as mine is silent as a baby sleeping.
