Building an i7-7700, most cases have the option for 4 or 5 fans, but come with 2 or 3. If I am not playing any games, just email, web and photo editing, are more than 2 fans needed ? (have 3 hard drives)

Hello, i am getting a CPU fan error, and CPU overheating message after boot. My PC stays on long enough to get into BIOS, BIOS says the CPU temp is 85° celcius. Then it shuts down to protect the cpu from what ive read. I have a corsair H100 hydro cooler. I removed the heat sink from the CPU...

I have this choice, in my case, the Xeon is more expensive than the i7, so yeah. Is the higher priced Xeon worth it for gaming?
