One thing stands out drastically to me in that screenshot & that is the CPU is running at 1600MHz instead of 3600Mhz base clock, so it is throttling somehow.
Can you try setting your power plan to Maximum Performance (I just took screen grab of mine set as Balanced as is), setting both drop downs for the
Processor Power Management to 100% & then check the temps again with AIDA or HWINFO.
That might explain the low temperatures that AIDA is reporting as 29C in the temperatures we have been having would be very low even with custom water cooling & air conditioning in my experiences.
