After trying this and that I got it to be near dead silent. I have an Antec sx1030, changed the PSU fan to a Panaflow, the intake fan is an enermax adjustable fan plugged into the mobo, the exhaust fan is another enermax adjustable fan running at 7 volts, then I am running a Zalman 3000 Heatsink/Fan in noiseless mode. Cooling is sufficient and I have a pretty much silent computer! 🙂
