You claim the cards didn't go above 80ºC but it is incorrect. What never went above 80ºC is the GPU core.
Load Gpu-z, look at the Sensors tab and see if it shows VRM temperature. If they go above 80ºC, you MUST undervolt your cards with VBE7. If it doesn't show anything, then it's even worse because one never knows. You might as well pray. I've seen 110ºC vrm on a 7870.
You should undervolt anyway, to protect the GPU, the vrm and the PSU, reduce heat and save power
Then you aren't suppose to overclock the core for getting hashrate. The ram first, to 1500, 1625 or 1750 Mhz, then the core only up to a point
The Cooler Master PSUs aren't that good either.

Yes I thought about it too but problem is there are no sensors on vrm so gpu-z won't show the temperatures.
I discovered something strange today, cards came with bios 015.040.000.001.000000. When I search it on net, it shows its R9 280x bios ? Couldn't see that bios in techpowerup's bios list for 7950 sapphire. Any ideas?
