I was quite happy with the cooler that came with my i5 3570K. When not overclocked you couldn't hear the fans at all. I always wanted to try water cooling so I installed a H60 (gen 1) system and now I have to listen to the constant low hum from its fan.Intel coolers are nearly unusable on most of their cpus and in most use case scenarios. The cost to them vs the cost to us for them including what most will never use is a metric I'd be very interested to see.
