Generally we do not worry about the hardware factors of our Laptops or PCs like CPU fan speed, core temperature, clock speed and etc assuming them to be running just fine. Very recently I came across a situation where I wasn’t sure if my laptop’s fan was working properly. Though the laptop manufacturer had provided the software to track various parameters like hardware and software controls no where it had the additional details like fan speeds, voltage, utilization and more.
I came across a free utility called Open Hardware Monitor, its an open source application and supports most hardware monitoring chips found on mainboards available today.
This application does not require any installation and you can just click to open and run it. Hardware Monitor runs on 32-bit and 64-bit editions of Microsoft Windows XP / Vista / 7 and most x86 based Linux operating systems. You can download this for Windows / Linux from HERE
