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.
Based on the [H] review, the Macho seems to be a much better choice - similar performance and much cheaper. Do you really need that kind of cooling for the 2500k though - they don't get terribly hot unless you are looking for an extreme overclock. You could easily get by with a smaller and cheaper heatsink - the H100 looks like overkill for that setup.
