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.
If you like the brass/copper look of the heatercore, you can clear coat it also,and it will retain its shine without tarnishing,i prefer to paint mine gloss black and then i clear coat it after words, it really makes the paint allot stronger against scratching also .But yeah the guide at OC is a good one to go by for sure.
