iPhone 11 Pro Max CPU Problem.

I know I have asked this question before but here is more info.

So when I first got my iPhone 11 it ran just fine for a few weeks after the first few weeks the screen would freeze upon saving images on the internet. Time went by it was not a big deal, but I noticed it would happen longer and sooner than before. Recently it will freeze quickly and get warm real warm. Today I started the game black desert mobile a second after starting the app for it to download additional content the phone screen freezes and wont let me use it and also gets warm. I have to set the phone down for a good 10 maybe more seconds before it lets me use it again, but then as soon as I unlock it it freezes again. I put the phone up to my ear to hear if it was making an internal noise and can hear a faint fuzzy crackle noise coming from where the CPU should be. I restarted the phone and let it sit for a good 3 or 4 minutes then listened to it only to hear a quiet high pitch noise along with a 2 click sound followed by a pause in between each two clicks. I started black desert again and immediately freezes the screen followed by the same fuzzy sound from before and warmth building up where the CPU is. I really don’t want to send it in for a new one because I would have to pay a small deductible even though I think it was out of the factory faulty hardware. I should not have to pay to get my phone working when it was already messed up before I got it. What should I do?
