Definitely worth having tool for monitoring your hardware.
I just noticed that they have PRO version which supposed to give you controll of fans speed.. that should be even more awesome!
HWMonitor is a hardware monitoring program that reads PC systems main health sensors : voltages, temperatures, fans speed.
The program handles the most common sensor chips, like ITE® IT87 series, most Winbond® ICs, and others. In addition, it can read modern CPUs on-die core thermal sensors, as well has hard drives temperature via S.M.A.R.T, and video card GPU temperature.
Special hardware monitors such as abit® uGuru and Gigabyte® ODIN™ power supplies serie are supported too.
HWMonitor Pro adds the following features :
Watch the sensors of one or several distant PCs through a simple TCP/IP connection.
Save monitoring data and generate logging graphs as bitmap files.
Sensors in system tray, editable sensors labels …
Fan PWM control (for ESA compliant devices).
