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.
How SFF is your SFF case and what processor are you trying to cool with it?
I can also recommend the C7 as the deal to beat - it's excellent for the price/size.
The M9i is pretty short at 124mm so it may fit in some "SFF" cases, if it's one of those SFF cases that isn't really S. Also have one of those and it's got to be the best value for an aftermarket heatsink at $20.
