Your i7-10700F runs smoothly at 4.5GHz and slightly lower idle at 2.9GHz. Improving cooling could help maintain stable performance, but keeping turbo boost permanently at 4.8 or 4.7 might stress the CPU over time. Monitor temperatures closely to avoid long-term wear.
As long as the CPU temperature stays below 100°C, turbo boost works fine. Going past that will cause the chip to slow down automatically. You won’t damage it unless you have a K chip and deliberately force it into unsafe conditions—even then it will still stop at 110°C.
The 4.8GHz figure refers to the single-core turbo speed. It seems the multi-core turbo isn't as fast as the single core, and using that single-core turbo on a non-Z chipset board across all cores might not be feasible long-term. Z boards could have some possibility with BCLK OC, but it's a complicated scenario.
