They are worth it, by a mile. Sure, they are overkill but overkill means your CPU lifespan is increased dramatically. I spent $190 on my CPU and $100 on a noctua nh-d14 cooler, and I don't think ive ever been happier with a purchase. From stock to the new cooler, my idle times went from 30x to under 5c, and under load it went from stock 60c to 30c under load. Yes they are more expensive but besides the 40,000 hour rating on the fans, the thing COOLS YOUR CPU LIKE NOTHING ELSE!
