众所周知,d915发热量较大。于是,各散热器厂家大做广告,各种纯铜散热器接踵而来,价格不菲。可是,纯铜的效果一定就是最好的吗?我从下面几点谈谈自己的看法:
1. 外界环境对散热效果的影响
一般来说,外界环境较低时,温差较大,纯铜散热器效果好些;反之,铝制散热器效果较好。
2. 导热速度
铜的热传导率是401,铝是237。也就是说,同样截面的铝和铜,铜的导热速度要快得多。
3.散热效果
铜的比热是0.39,铝是0.9;铜的密度是8.9,铝是2.7。利用我们初中时所学的物理知识算一算,很容易知道铝的散热效果好。
所以,铜铝结合的设计不只是为了节省成本,更是为了集百家之长!
现在do不尽的915功耗已降为65瓦,选什么样的散热器,你心里有底了吗?

楼主,我的电脑也是PD915的 最近机箱怎么经常吼得吓人。 有的时候只开一个QQ使用率都会上升到百分之九十几! 请楼主在百忙之中抽空解释一下。 我的QQ:56753971 | |

我的DO的冬天要把硅脂擦掉,要不温度上不来,现在市温20度左右全天挂机游戏,也才48度。不过要给U上硅脂了!呵呵!915还是不错的! | |
