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 came across your post; I was searching on how to disassemble the Reserator XT because mine just died this past weekend. I changed the coolant about 6 months ago (after one year, just as suggested in the manual) and noticed how it had solidified, and the rig never worked correctly thereafter...
