i need a couple case fans. Two in back, one in front. Unfortunately, i don't know what brand to get. Loudness isn't too much of a factor except if its gonna cause a headache. I just need proper cooling for my AMD XP 1600+ and Gigabyte GA7-VRXP. I bought the Volcano 7 for the chip, but for the case cooling, what fans are best? i need two 3x3 for the rear and one 3.5x3.5 for the front.
