Sorry first of all im a newbie and want to know what's the problem to my CPU

My cpu i5-7200 ,, with segoteop lux as case
I change my front intake fancase to Corsair ML120 twinpack 3 of them
and back exhaust become Noctua F12 2000pwm and top exhaust Corsair ML 120 twinpack only 1 at top back
my CPU heatsink is Deepcool gamax 3000

My CPU Heat was 60 before in 80% perfomance and now its become 80++
i want to know what is the prob with my CPU?? the other like VGA or MOBO or PSU all become cooler only the CPU got this prob

** my friend told me either the wrongway to applying the thermal paste
or the heatsink not properly intact
