AMD will be supplying new Wraith Ripper coolers designed by Coolermaster that will allow the Threadripper 2990X to hit 4 GHz on all 32 cores on air. This was demonstrated during an AMD event recently held in Maranello, Italy. Getting all 32-cores to overclock to 4 GHz is a commendable feat, which implied much higher boosts on single and fewer cores.

What's the ambient room temperature when this was tested? Can it still hit 4 GHz on all cores without thermal throttling if the room temperature will reach at least 32 to 38 degrees celsius?
