When i work on a cpu angry project the fans spin a lot. Of course this is normal. But if I get up from the machine for a few minutes i usually not turn off the computer. Would be fine a power performance function in the background where iclone turning into power save mode if nobody not use the computer after 5 minutes. It's not an important function, but environmentally friendly. The internal Windows power save mode some times not good choice so i hope you can implement this.
