I recently repaired my PC after having some hard drive issues and did a factory reset. However, I've noticed that when playing games like Elden Ring and PEAK, my CPU temperatures are hitting 90-100 degrees Celsius, which is alarming! In contrast, my GPU temperatures are around 50-60 degrees. I'm relatively new to PC gaming and I'm confused about why this is happening. I didn't experience high temperatures before the repair. Could tweaking the fan speeds in the BIOS help? I'd appreciate any guidance on what I should look at or adjust.

You should check a few things: 1) Make sure the CPU cooler is properly attached and that you removed any protective film if there was one. 2) Have you applied thermal paste recently? It's important! 3) Check if all fans, including the CPU fan, are connected properly and spinning as they should.
First off, what CPU cooler are you using? Knowing this can help figure out if it’s adequate for your CPU. Also, did you make sure to install the cooler correctly with the right hardware? It’s easy to overlook that during repairs.
When you say you did a factory reset, did you just reinstall Windows? Also, check if the thermal paste on your CPU has dried out, especially if you've touched anything inside the PC during repairs. Verify that the CPU fan's RPM looks normal in the BIOS, and if you have any fan control software, make sure the settings are correct.
