As far as I can tell, these temperatures are too high, but they probably aren't accurate as I've read.
Open Hardware Monitor recorded maximum temperature is 72.5 degrees C. It's currently hovering around 35 with a virtual machine idling. It was just installing XP on the VM and was hovering around 60.
MSI 970 Gaming Motherboard
AMD FX-8350 4.0 GHz with stock CoolerMaster cooler

Corsair Force LX 128 GB SSD
Seagate Momentus 750 GB 2.5" 7200rpm HDD
750W EVGA PSU
2 80mm Intake fans (with filters, one of them is kind of blocked by the hard drive enclosure)
1 80mm top fan

There isn't really any ventilation at the back of the cavity where the tower is. I think it may be necessary to add holes to the backing ply or get a better CPU cooler. Especially since I live in Australia and summer is approaching. It's not even hot at the moment and I'm getting these reported temps, which will only rise as the heat rises.
