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 heat dissipation of a 120mm RAD should be enough to reach 4.5Ghz. If an air cooled, single 120mm tower cooler can cool a 3770k to 4.5Ghz, then a water cooled setup of the same dimensions should be able to acomplish it as well.
