I need advice for a good Heatsink/Fan to use with a Thoroughbread-B AthlonXP 2400+. Low noise is the priority here, but I would like to strike a reasonable balance between noise level and performance. I intend to run this CPU on an ASUS A7N8X and using its ability to unlock the CPU multiplier run it at an elevated FSB speed. This is where I am expecting most of my extra performance to come from, but a little bit of an overclock wouldn't hurt.
