Cpu cooler

Hi, looking for a good cooler for my AMD Athlon 64 4000+ San Diego 2.4GHz 1MB L2 Cache Socket 939 Processor. I t will be overclocked and like to keep it under $40, thanks

The Arctic Cooling Freezer range are inexpensive & for their price do a very good job.

$40 gives you a lot of choice. I can recommend the Thermaltake
Silent Boost. All copper, excellent cooling, very quiet.
