Undervolting CPU on G3-572

NSJ006

I want undervolt my i5-7300HQ my temp sits aroung 65 while gaming and someone says undervolting cpu reduces the heat. So, please help me to find suitable undervolt value at which system run stable and also GPU 1050Ti not throttle while gaming.

Start by reducing the CPU Core & Cache by -80mV, you'll need to test and reduce the power incrementally to find the best balance.  Ensure that your backed up as although there is little risk if the system crashes as the wrong point in time it may result in corrupted data.  No CPU is the same so no specific value can be offered.

Alter a good deal of testing on my G9 793 i7 7700HQ , GTX 1070, 32Gb  Ram with Prime95:

CPU stable down to -140mV
System locks up at -150mV
No thermal throttling at -130 over sustained testing all CPU cores at max frequency.

Opted for Core & Cache voltage offset of -130mV as this offers a good reduction in overall CPU temperature, even under massive sustained synthetic load no thermal throttling.  Set profiles for Performance and Battery with only difference of disabling Turbo Boost on battery to help extend the runtime.  If any issue occurs I'll simply reduce the Core & Cache offset by 5mV.  Disabling Turbo Boost on non CPU intensive games will also reduce temperature under load.

Intel XTU service I left as the default delayed start, equally with the 7700HQ I strongly suspect disabling the service will have no effect (currently XTU is disabled).  As per guides if wanting to auto start ThrottleStop best to delay 30-60seconds or more.

CoolBoost on and Frost Core installed

Temperature of 65C isn't something to be concerned about, considering that the throttle temperature is 97C. What temperature the GPU is running at? You can download HWiNFO to record the temperatures of the CPU and GPU. Post the max and average temperatures, while gaming.

Just to update: I enabled the XTU Service again as being disabled effected PredatorSense with no CPU frequency being displayed.  I strongly suspect the service is just reading out data points with the likes of the 7700HQ and not effecting the CPU registers.  ThrottleStop I have set up with Task Scheduler for a delayed start to ensure no conflict.

System runs great with no indication of conflict between XTU, PredatorSense and ThrottleStop.  Just played a few hours of Cysis although old it can still push systems on max settings.  Average CPU temperature was 67C which is pretty decent, although Crysis is not CPU intensive, with the GPU getting the bulk of the workload.
