hikari20 - i run my Laptop-Fans at "FULL SPEED" with NitroSense
use a good headset or headphones that cover all of your ears and you wont hear it 
better a cool laptop than a quiet one 
HERE YOUR ANSWER:
to "lower TDP" on Ryzen Laptops (and therefore make them "cooler")
1. download: Releases · FlyGoat/RyzenAdj · GitHub Version 0.5.2
2. write a batch-file with these code - it will limit the APUs TDP to 15W (instead of 35W in your case)
@echo off
%~dp0\ryzenadj.exe --stapm-limit=15000 --fast-limit=15000 --slow-limit=15000 --vrmmax-current=65000
echo MSGBOX "APU runs now with 15W TDP" > %temp%\15Wmsgbox.vbs
call %temp%\15Wmsgbox.vbs
del %temp%\15Wmsgbox.vbs /f /q
exit
3. place this batch into the RyzenAdj folder
4. run the batch as admin - you can also create a desktop-shortcut and check "run as administrator" - this will allow fast usage
this will reduce performance a little but will result in better temps
you can play around with the "15000" - like make all 3 to "21000" and your Ryzen 5 3550H will have a TDP of 21W
you HAVE to change run this after each reboot - TDP will be revert every bootup
