fyi, i've been used called throthlestop (undervolting software)..buat icant undervolting it anyway cause Intel got like protection to its processor, but i activate indicator in throthlestop called "disable turbo"

And i've decreasing like processor performance to 99% (100% at first) forgot what its name is. Ive done all that things due to my overhest problem
