背景:平时没有观注CPU温度,以前都上81度,报警了,今天给超小机箱里的笔记本硬盘给挪动了下让CPU的风能更多的从下面吹到盖板上的孔里吹出来,一看有66-76度之间,查了下好像是正常的。
一、感觉4核心的CPU温度还是下面这个值比较靠谱,特摘录如下:
CPU温度高低不只是跟风扇,机箱内温度和室温都有关。机箱内温度较室温高3-11度正常,过高则因为机箱散热不好。CPU温度较机箱温度应不高于19度,较室温高应在8-21度之间.
一般CPU工作可以在25-75度,闲时40--50度,
较忙时50--65度,全速工作时65--78度,过高会重新启动或死机,60度的温度就有些高,温度在50度以下比较合适。
(个人认为所谓全速:不知是不是CPU 100%的运行?要这样,我这电脑估计得上90度,平时就看个片,上个网,打个游戏也就耗费CPU 2%。)

二、从BIOS里可以设置风扇的是PWM还是恒转速:
方法如下:启动电脑--进入bois(多数电脑开机后一直按Del键可以进bois,不行的可以参考你们主板参考书)---选择 power 菜单---pc health 里面即可查看当前处理器等硬件温度

三、笔记本多少正常:
笔记本显卡散热问题应该比笔记本CPU更严重,特别是中高端独立显卡,玩游戏时温度飙涨是难免的事,笔记本显卡的耐热温度是120度,警告温度是90度,通常认为到80度左右是正常的,满载应该在85度左右,如果再高就不太正常了,可能需要加强散热了,或清除灰尘。

二)Linux如何查看CPU温度:
CentOS系列:
1.yum install lm_sensors;
2.sensors-detect #注意:这些命令执行的过程中,需要你 YES/NO/SELECT,直接一路YES,就OK啦!
3.sensors
最后的信息大致如下:
