If the processor idles at a high temperature: disable all 3 bios options for Precision Boost Overdrive (PBO). Set Windows Power Plan (not AMD's one) for "Balanced".
(If you get the 3600, 2600, 2200g, or 2400G the Wraith Stealth is a bad cooler. Try the Cooler Master 212 evo or the smaller Antec a40 pro. Thermal Grizzly Hydronaut is a very good paste.)
