Karlog22, The two fans under the PSU are installed in opposite directions? With all the side panels on the front air intake will be enhanced with all rear fans pulling case air and exhausting out the rear. Please take a tissue and find which fan is reversed and switch it around. To my eyes the upper case fan is pulling air in from the rear and the lower is exhausting out the rear......set them both up for exhaust and if still loud then replace. I would clean the fan blades, mobo, case and PSU with compressed air and a old tooth brush.
