My computer is way too loud. It's a Systemax system fairly well built with an Intel 930D processor, NVIDIA 7900 GTX graphics card, 2 X 250 SATA 10K drives and 2GB of Corsair RAM with the light up LEDs . . . Anyhow, the fans that came with it are obnoxiously loud, so I'd like to replace them all (except for the one on the graphics card) What are your recommendations for the following? CPU Fan 3X 80mm Fan 1X 120mm Fan I need super quiet fans with good airflow as the system generates a lot of heat. I'm running intense workloads on it most of the day and often overnight.
