问两个CPU散热器有什么分别麽

阿尔法400plus是搭配你的775cpu，如下是泡泡网的相关介绍 http://detail.zol.com.cn/cooling_product/index150972.shtml

贝塔400 plus Up to AMD AM2 all Series Up to AMD K8 all Series 阿尔法400 plus Up to Intel Core 2 Extreme QX9770 (LGA775) Up to Intel Core 2 Quad Q9550 (LGA775)Up to Intel Core 2 Duo E8500 (LGA775)Up to Intel Pentium Dual-Core E2220 (LGA775) Up to Intel Pentium D 960 (LGA775) Up to Intel Celeron Dual-Core E1400 (LGA775) To Intel Pentium 4 all Series (LGA775) To Intel Celeron D all Series (LGA775) 所以你应该用的是阿尔法400 plus

贝塔的散热效果更好点 建议选择酷冷至尊暴风S200
