Just like you, I had a 212 and switched to the 100i, and it was a great upgrade. With the 212, it was getting too hot under load at stock. With the 100i I can get a 4.4 overclock on my 3770K and still keep very good temps. Hopefully my 100i won't croak on me like it has for others. I'm sure Corsair will take care of me if it does!
