Heat problem and questions

[Whitebear707]

Hi, I have a i7 8086k on a Aorus z370 gaming 5 motherboard. The case is a DIYPC Vanguard-RGB. 3 front fans as intake. 3 fans on top of case front one as intake and the other two as exhaust. and the rear fan as exhaust (7 fans total).  Thermal paste is IC diamond and the heatsink is a Aorus ATC700. power supply is a Corsair CX750M. And my graphics card is a RTX 2080 TI.  I use my pc for work, video conferences. temperatures are never a problem until i play games. GTA V, RUST, Need for speed Heat. Flight Simulator 2020. after 45 minutes of playing the cpu starts to get in the 85c, to 90c degrees.room temperature is normally between 30-32C.  i dont like running the CPU that high. i was thinking on removing the fans from the heat sink and replacing them with some Noctua or corsair fans and changing the thermal paste to thermal grizzly Kryonaut. Do you guys think this would be enough to keep it under 80? or would you recommend replacing the heat sink all together? I don't want to go water cooling because im afraid of leaks. i don't have the budget to buy another motherboard and processor.

I am not sure how good that heatsink is... ill just assume "its fine". That chip is not exactly a cool one, and I wonder if the Aorus is doing any funky auto overclock/all core turbo stuff like multi core enhancement. If multi core enhancement (MCE) is on in your BIOS, turn that off. What MCE does is boost your all core turbo to match a single core turbo (which for you is 5 GHz), and its likely pumping way more volts than actually needed to do it; effectively its a really dirty overclock.

 

I would check for MCE, because if games get you into the 90's, real workloads would put you beyond 100c...

I checked and MCE is disabled. if it was overclocking, i think it would heat up within the first 10 minutes of game play right? because it takes about 45 minutes to reach 85c. My case does have good airflow. thats why i think the heat sink is not cutting it. but would changing the fans on the heat sink would it make any difference?
