Get good fans, make sure the thermal paste if good, etc.
AMD stock coolers are generally pretty good, so no worries there
But before you mess with all these things, make sure your bios has all fans in the correct mode (DC or PWM) and that the profile is set to silent (set a curve manually if you feel you know enough about these things).
None of the settings will work if you have DC fans and the BIOS has them set on PWM, they will just spin like there is no tomorrow (not sure what the opposite does).
Edit: some stupid motherboards force you to plug DC fans on different headers.
