i want cpu to remain below 90c during benchmarking, there are videos on youtube about bios , but most of them are of other brands board, and they have successfully done that. is there any complete guide for msi board ? , the manual only says about board but nothing about i9 or specific cpu.

The obvious question is why? The Raptor Lake processors are designed to reach the thermal throttling point and will keep drawing more power until they do. It's a different approach to previous generations where the aim was to keep the processor from reaching the throttle point and it takes a while to get into that mindset. If you're aiming to max out benchmarking, then ideally you want to get it to 98-99 on the hottest core (and throttling obviously happens per core, so you need to monitor all core temps, not just the average), just before throttling kicks in while drawing the maximum load. To do that, you'll need to limit the total draw power, which will take some experimenting to find the ideal point. Otherwise, you can just set an artificially low limit on TDP and run it cooler, but your benchmark will be less than optimal.

also undervolt it!,it will save power,and a lot off heat and you relly could get even better performance.

and important, what hardware and especialy cooler and case are you using, fan setup ect, all matter

What cooler are you using?
I mean that's most obvious reason your CPU gets this hot.

Yes. I found one option called throttlestop software many laptops guys use it also xtu . I will try that . There is always around 2 to 4 cores mixture of e and p cores . I got 3900 on cinecbech multi-core . Which is fine i guess

360 cooler master V2 AIO. I got 3900 in multi-core in cinebench. Which is pretty good score. But there are mixture of p and e cores around 4 cores always reach 100 degree

Yeah these are pretty hot CPUs. Have you followed the AIO manual while installing to ensure it's correctly mounted?
You can try things like undervolting and reducing max CPU usage in windows power plan to 99%. Turbo boost will cause higher clocks resulting in higher temps.
Also Intel does a terrible job with IHS.
