What's a good quiet cpu fan to get for an MS-6378 motherboard with a 1.3gig athlon in it. Getting it on my grandparents computer, there cpu fan is quite loud. All they use it for is basically internet, email, and solitare. Nothing that would make the computer get too warm. The case has a couple fans to pull air through, and theres only one cd drive and hard drive and an 8mb g-card, so really not much heat coming from anything else.
