I have decide and try out to change cooler pad to Grizzly Thermal pasta on the Z370 Classified Chipset so the result is very good much better with temp has drop about 30c ish from 74c on pad and the Thermal Pasta drop to 56c ish at IDLE. Here pics below >
 

Before use Thermal Pasta the temp is at Idle reach at 74c because I have sli two Graphic cards made more hot near to heatsinks on chipset
 

This pad help to keep cooler on chipset but it not good enough when playing games it reach at 94c and Division 2 game reach 98c made me really so worry it so hot and don't like hurt my MB!!! 
I decide to remove pad and replace Grizzly Thermal Pasta.....
 

 
 
So the result is so awesome more cooler ever I see! It drop about 30c ish to 54c at Idle so Games heavy load … Chipset didn't rinse very much to 75c ish depend on your games!

 
Bear remind you know that Heatsink Chipset gap between to Motherboard is about 2mm so you need plenty thermal pasta!!! 
What a great Motherboard 
So happy Bunny

    My Z370 Classified K PCH also runs hot ~74°C, I noticed in the BIOS the PCH voltage was being reported as 1.094 V on Auto, which is almost 0.1 V over the default.
     
    I set it manually to 1.00 V and now it runs much cooler ~55°C, so you should probably check this also.

    how is the airflow in your case ?
     
    Those heat sinks need air movement to keep them cool
     
    Thank you for sharing your results
     
    Was the stock heat sink difficult to remove ?

    That Good 
    Thanks for tell us! I prefer leave on Auto for overclock!!!! I can't stand watch this too hot! All other temp is good! I sure this pad is become thinner and it easily made too hot reach at 90c ish when use two graphic cards!!!

    In my room is cold at 18c cos UK is winter coming!! 
     
    My cases are good very cold inside my case got 4x 140mm fans push and pull on cooler radiator at the front of case and 4x 120mm 2 for intake air and 2 for Exhausted
     
    It not very difficult to remove heat sink it just two small screw to remove that it
    but it hell you need to remove all hardware e.g cpu, pump and graphic cards etc and discount all power supply from motherboard then take out motherboard from the case and after apply pasta thermal put all back it bit take time!!!!

    Hope you replaced the coil cell battery while you were at it

    I have EVGA Z370 FTW board and I can confirm high temps around 69-72 at idle, and as mentioned they drop down to 50-58 after lowering PCH voltage in bios.
     
    I had an Intel DZ68BC board once, and it also had high chipset temps. Applying CPU thermal paste instead of thermal pad under the chipset cooler improved the temps drastically.
