My assumption is that those are VRMs(Voltage Regulator Module). I have read up on how many motherboards based on AMD chipset(from Gigabyte, Asrock, and many others) read that temperature high. There have been people trying to put a little fan to assist cooling, but at a questionable benefit. There is no proof that those high temps shorten the life of the motherboard. For your sanity, you could reseat the VRM heatsinks, as they might be loose because of the shipping of the motherboard or other reasons.
