The biggest thing, find out what the exact specs are for your CPU.
Then go from there. That's your starting point tho.
"grep model /proc/cpuinfo" returns 12 instances of...
model : 165
model name : Intel(R) Core(TM) i5-10400 CPU @ 2.90GHz
"I asked Mr.Google" and the best hit was...
https://www.cpu-world.com/Compare/463/Intel_Core_i5_i5-10400_vs_Intel_Core_i5_i5-9400.html
...which compares my CPU against a previous generation. The "model" and
"model name" both match. My CPU is stepping 3 versus 5 on the web page.
The "Core name" is "Comet Lake-S", which matches output from "lspci" on
my system. The base max frequency is 2900 Mhz and the "turbo frequency"
is 4300, which matches what I see during compiles.
Now for the important part...Max temperature = 71.3 C (160.34 F). So
schedutil is not a problem.
If it were my CPU with a max of 70C and I was running at 48C, I wouldn't
be worried. In degrees F, that's a difference of about 40 degrees. It
seems your max temp and mine are pretty close. You are actually running
a little cooler than mine.
Unless someone else sees a problem, I would carry on. The CPU at those
temps should have a nice long life. You can also enjoy the speed increase.

I have a (now quite old) MSsurface-pro4 with an I5 - it runs about
50-60c on normal use but compiling (for example) webkit-gtk and
Libreoffice causes the temp to go way too high. I have a script checking
the cpu temps - at something like 65 deg it switches from performance to
the powersave governer (helps some), at greater than 71c it hibernates.
After a cooldown I restart it and it continues on. If I move the 71c
trippoint to 72c, it will reliably hard lockup after a short delay.
Ideally, I would like to be able to tune MAKEOPTS dynamicly to reduce
the number of cpu cores to help further but I dont believe portage can
do that.
I am in the process of setting up distcc to try and help distribute the
load while limiting the i5 to -J2 which I hope can speed things up
whilst still keeping its cool.
