SpeedFan 4.35

[zatoicchi]

SpeedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M.A.R.T. info for those hard disks that support this feature and show hard disk temperatures too, if supported. SpeedFan supports SCSI disks too. SpeedFan can even change the FSB
on some hardware (but this should be considered a bonus feature). At the lowest level, SpeedFan is a hardware monitor software that can access digital temperature sensors, but its main feature is that it can change fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your pc, thus reducing noise. Several sensors, like Winbond's and the AS99127F support fan speed changing, as well as others from Maxim, Myson, Analog Devices, National Semiconductor and ITE, but the hardware manufacturer must have connected the relevant pins to some additional, yet trivial, circuitry.

Its a Cool thing to have such a tool to monitor your case temps since you know its hard to figure out how many hours you been turning on your PC or like forever LOL also that HD temp function would be awesome,but one thing,you know HDs always work in the core of your case so I guess you should familiar with its high temps

Thanks for the share, it monitors more stuff and is generally better than ASUS Probe, which is what I have been using so far
