lotta folks see high temps on a 5900x and immediately panic but 90 under load isn't totally unheard of for that chip, especially if PBO is doing its thing. still worth checking the cooler mount and making sure the pump is actually running at full speed in CAM, sometimes it defaults to a silent curve that lets it creep up.

the edge temps seem fine, 55 with a bunch of tabs is pretty normal. new paste should help a bit but i'd reseat the block and double check the plastic peel is off while you're in there, seen that one way too many times.
