I serviced a bad CPU fan on a friend's ASUS laptop....Ivy i3 IIRC. Anyway, I fired up Prime95 to see what the fan sounded like under load when she first handed it to me. Much to my surprise, the CPU never ran any faster than ~750MHz. (that particular chip was around 3.1GHz max frequency) Temps were obviously fine although the fan bearing was indeed dying. After replacing the HSF, I discovered that ASUS' bloatware had added it's own batch of power profiles that could not be overridden...even by setting to Windows' "balanced" profile. After uninstalling the antagonist software, everything went back to normal. I wonder if Samsung had something similar in the review model that the reviewer didn't catch.
