What is your chassis? What is your case airflow like? How do you have your fans set up?

This won't fix anything. In fact, going from 10 to 7 is a major downgrade. Hard to believe, I know. But it's true.
i dont know really im new in this domain but i bought it like that is not me who built
also motherboard is cool and not hot in temp

Intel turbo is misleading. Turbo is a variable usage. Chrome or whatever is only using One core, so that core can safely Turbo to the max settings. Fortnite is using upto all 4 cores, so turbo is restricted to a lower speed by the Intel set power limits. 3400 MHz (1 core) 3300 MHz (2 or 3 cores) 3200 MHz (4 cores).

If you have a Z or H rated motherboard with a x68/x77 chipset, that can be manually overclocked upto 400MHz by changing the turbo multiplier.

I don't see any reason for any game to drive speeds below the base 3.1GHz of the cpu unless there's an issue such as temps or worn out cpu/VRM's not allowing full rated speeds. If it's just fortnite and no other program does this, I'd suspect it's a game issue, not an actual hardware issue.

If you use coretemp/Realtemp and task manager at the same time as running Prime95 small fft and your speeds/temps are as they should be for 4 core heavy usage, I'd be almost certain that fortnite is bunk and can be ignored.

i have a biostar motherboard model H61MGV3 i thing no overclocking option is available on it

That's an x61 chipset (H61xxxx) so no OC available other than BCLK manipulation. It only worked for lga1155 cpus on those 2 chipsets. It was one of those things Intel was testing out for viability and usage, just like the short-lived Lucid Logic ability to basically tie in igpu usage to discrete gpu usage for better picture quality.

really i dont know what to do but ill play on base clock till i find a fix
