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.
Yeah, a lot depends on your case airflow. For example, I have a H100 with a push/pull setup (a air filter between to keep dust out) 2 120 fans blowing straight down into the case with a 120 exhaust fan and 2 120 side fans aimed directly at my 2 reference cards.
