It's not normal for the protest beeps to happen on startup. But, considering the low temperatures at which it is beeping, it may be a bug. 50 degrees is fine for both AMD and Intel CPUs. Check your fan as suggested and check the cut-off/safety point at which your beep alarm goes off (this is usually in the BIOS); it may be set too low.
