So the temperature will be reduced a little. when the temp is the some section, eg. the 60°C and 65°C are the same section when the section is 60°C~70°C， the speed of fans will be the same. > Is there a way to query the sensors ? Please insmod ec_ftd which is one of the ec modules. And then type "cat /proc/ft" , the output: "1.31 0x01 4705 0x00 56" the 4705 means the speed of fans, 56 stands for the temperature the ec_modules source URL: http://dev.lemote.com/code/ec_module git URL: git://dev.lemote.com/ec_module.git > Cheers > r1 > > > > -- --------------------------------------------------------- Hongbing,Hu (Software Department) Tel: 0512-52308631 E-mail: huhb@lemote.com MSN: [huhb04@gmail.com] JiangSu Lemote Corp.
