Exactly. If 14nm can take it there's no reason 22nm can't lol.
1.45v is more or less safe but I wouldn't use that much if I depended on the system. At this point the 4690k is pretty limited in a lot of ways and it's not like it was ever an expensive CPU so yeah hitting it with gobs of vcore can be fun.
Like I said, mine did 5ghz on a garbage air cooler and even on air it kept scaling reasonably well. Sadly my 4790k doesn't.
