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.
Any of the 1155 mount HSF will work on the 1150 mounts. But I'm sure you know this. So basically any fan and heat sink will work that is out. But once you start overclocking then you will need a better one. After 4.5GHz they start to get a little toasty.Just depends on your needs and if you need to match a color scheme. Most seem to be happy with the H80i-H100i aio loops.
I know this doesn't really help you looking for a deal on one though. Sorry I couldn't be of more help to you.
