It's 10 degrees (Celsius) cooler in Cinebench and barely moves over 40-50 degrees in actual gaming!
If you are keeping CPU temperature at 40-50 degrees under load, you are working your cooling system too hard, and your system is actually using
more power and producing
more heat (and noise) overall. Slow down the fans and let the CPU work at the high end of the temperature range it is designed for. Only increase fan speed if you run into the CPU's temperature limits, affecting performance (boost behaviour, throttling) or stability (when overclocking, undervolting).
PC enthusiasts and hardware reviewers are too concerned about temperatures. I suspect there is some confusion about temperature and heat. Somewhat counter-intuitively, natural heat dissipation is more effective at higher temperatures.
In a notebook computer there are some ergonomic issues though (uncomfortably hot keyboard, in particular), that may warrant more cooling (and fan noise) than the ideal.
