Whatever I do on my AR51SU - even with 100% CPU load - the fan does not spin up accordingly; it sometimes does for a couple of seconds without any special reason, but not at CPU full load! Very hot air is coming out the rear vents, and I'm anxious it's overheating... Is it normal? What can I do about it - on my other PC (a workstation), I'm running an utility called SpeedFan, which controls all the 6 fans on the system so that they only blow fully at CPU loaded 100% - is it safe to use it on Vaio?
