My CPU has been "Overheating" like, the idle temp is 40c and the web browsing temp is around 56c and when running a virus scan, it goes up to 81c and when exporting a video in Adobe Premiere Pro, it reaches 84c while increasing my fan speed to almost max using predator sense and opening my window (It's -12 outside right now🥶) because it doesn't increase it enough automatically. And I think the current cooler right now in my PC is a stock intel one, so I would like to upgrade to a better cooler. But I do have some questions. Will this void my warrenty? How big should the cooler be? What cooler should I use? Do I have to reconfigure anything in the bios? Any other steps would be helpful since I've never upgraded/touched a CPU cooler in my entire life.
My PC specs are: Intel i7 9700, RTX 2060, 16GB RAM, 500 WATT PSU
