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.
Hm... it seems like your clocks don't actually boost itself above your set OC. The fluctuations might be from thermal/power throttling, though I'm not positive it still does that with manual clock settings.
I have reds and while the keys themselves don't make a lot of noise, it's pretty hard not to bottom out with them. It's possible to type nearly silently with reds, but it's not practical.
