Right now I'm using the stock heatsink/fan that came on my CeleronD 3.2ghz LGA775. This is pretty much the loudest fan in my system. When I unplugged this fan for a second, the audio level was very nice with just a small hum from the power supply. What do you think will be the cheapest way to make it quieter? Can I lower the cpu fan speed with one of those fanmate knobs or will that cause the temp to go too high? If not, would this be a quiet option? Thanks alot
