I have an H60 v2(the 2013 version), and I have my i5-3570K at 4.5Ghz with 1.26v. I max out at 85 degrees with a prime95 blend test(24 hours). Also my pc was in a closed cabinet-type-thing when I tested this. With normal airflow(doors open), I get 69-79 degrees. It's up to you if this is too hot, but for me, it's perfect. I like it.
