This is all that should be needed for a modest overclock:These days "over_voltage=" is deprecated, instead we have "over_voltage_delta=" which just adds an offset in microvolts to the normal frequency/voltage scaling.
In practice, I find the default voltages to work perfectly well up to 3GHz anyway. So you don't need any over_voltage stuff unless you want to go to the extreme.
I believe force_turbo makes it run at full speed all the time, even when idle, so that's not a good idea.
With a good passive cooler, my Pi5 has been running for months happy and stable at 3GHz. The temps are nice and low and it never comes close to throttling under any load or stress test. It is also stable at 3.1GHz, but I like a safety margin.
A fan would help if the cooler is poor, or if the Pi is in an badly ventilated case.
I usually add "gpu_freq=1000" but I'm not sure it helps much.
"cat /sys/devices/system/cpu/cpufreq/policy0/stats/time_in_state" shows the frequencies the scaling governor is choosing.
