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.
Since the mounting holes for the P4 S478 and Xeon S603/604 are the same, is it possible to use high end P4 heatsinks on the Xeon? Say for instance the Thermalright SP94? if not the thermaltake, than which would fit and which wouldnt?
