Good price on an entry-level aftermarket cooler with no rebates to deal with. It's a decent option as a stock cooler replacement or as a spare.
Although possible with some systems, this is NOT a high performance cooler designed for overclocking. It is a compact tower cooler that will outperform most stock coolers with less fan noise. It has good socket compatibility, stands only 5.5" tall and won't interfere with RAM or motherboard components in most setups.
