частота проца i5 2450m

на данном проце при нагрузке (в играх) начала изменятся температура с обычных 3000 на 798mhz что сказывается на фпс в играх (начинаются тормаза). что мб причиной и как ее устранить? температура 81 C для данного проца вроде небольшая.

это и есть результат аида теста

"температура 81 C... можешь вскоре попрощаться с матерью .. и с процом возможно тоже!!! "
почемуто сегодня на асц мне сказали обратное:
-данная температура норма для такого проца под нагрузкой
