You could allways set your temp"s alarm to warn of any failier"s. My qx6850 quad core has a small overclock, 3.0GHZ to 3.33GHZ and with pump on no1 setting and all fans running at lowest setting it"s a joy to watch dvd"s and tv without wirling fan and high pump noise
with a cpu temp of 19c there"s not much point in ramping everything up
