Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
The fan is actually different [51-blade 5000rpm versus 47-blade 6000rpm on the 6970] but the real world noise level/temps should be about the same. The unlocked 6950 may run slightly hotter and quieter than the 6970 due to the lower maximum speed of the fan.
