这话讲不通
看cpu与核心温度差距说明核心和盖子之间热阻较大
你并不能确定两组sensor的可靠性。某些风冷AMD U的温度还低于室温甚至零下,你相信么?事实上,对于核心温度,测温软件只能读取Distance to Tjmax,然后计算出温度
If the DTS is reading 50 then you know you are 50 degrees away from the throttling point. If the maximum safe operating temperature for your processor (TjMax) is 85C and you are 50 degrees away then your processor must be running at an absolute temperature of 35C.
Absolute Temperature = TjMax - DTS
Intel does not publicly document what TjMax is for desktop processors. TjMax is fully documented for their Mobile processors but not for their desktop Core processors. Without this reference point, your absolute temperature data could be meaningless. Intel has also confirmed that there is no secret bit hidden in these chips that a programmer can read to determine what TjMax really is. The only thing a programmer can do is guess at TjMax and if he gets lucky and the reported temps look more or less believable then everyone is happy.
