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.
I have mine at 4.0 with 1.21V (bios set to 1.22) and using a AXP 140 with 1366 mounting kit. I have DDR 2000 and the voltage for the QPI is 1.4V and the ram itself is set to 1.64V. I idle at 40/42C and load at around 75-80C. I have 2 120mm fans blowing air inside my case on the side pannel (connected to a fan controller and set to lowest speed for silence). So, with almost no noise at all, im at 4.0 and temps are in check. My C0/C1 was only able to hit 4.0 at 1.35V and the heat was too much.
