I have a stock CPU cooler on my Athlon 2800+ with an Abit NF7-S Rev.2. It's in an Antec Sonata case. It's sounded fairly loud lately. So, I'm wanting to get a quiet CPU cooler. I've thought about getting one of the Zalman CNPS7000 series, but according to their charts, it's incompatible with my board, so I'm looking for suggestions. Thanks!
