download speedfan and check the temps there. if the bios reading IS correct then its not normal for a cpu to run this, but also an outdated bios version can cause false readings of certain hardware even cause problems. what to do ?
make sure to clean the dust, make sure u dont experience any crashing or freezing while ur gaming or just working or normal pc usage, make sure the heatsink on the cpu is properly seated. now if speedfan shows the same temps as CPUID then id suggest upgrading the bios and check. i forgot to ask what power supply u have and what other hardware u have ? does the cpu fan seem loud ?

Both are probably correct.

When running certain code or operating systems (such as DOS or, in your case, the BIOS setup utility) the CPU doesn't get a chance to idle, which causes the higher temperature.

Modern operating systems let the CPU idle (and in many cases can even lower the clock speed), which explains the lower temperature under Windows.

What happens to the CPU temperature in Windows when you put the CPU under load?

Fan seems normal doesn't do so much noise. fan speed around 1000-1100 rpm

Both CPUID and SpeedFan shows same temperature.

yes temperature goes up to 70 c(speedfan reading) while gaming.

70c is hot any crashing or freezing ? check the heatsink on the cpu if its installed properly do not attempt to remove it, if u dont know how, just make sure the cpu is thoroughly put in place. and make sure u provide good airflow to the pc case or tower. and check in bios if intel speedstep is enabled if it is leave it if not enable it that way the clocks will lower at idle and rise up when doing intensive stuff

It might if there is too little, too much, or a bit of dirt on one surface right now.
Clean off the existing compound with a quality rubbing alcohol and using an old credit card as a scraper if needed and apply correctly:
