I'm running my 2500k at stock turbo speed of 3700MHz at 1.2 vcore, it's fitted with a Corsair H60 water cooler and IC carat 24 TIM. At the moment the side is off the case to provide maximum air flow. After running prime95 for 15 min the temps accross the cores have reached 57c - 60c. The cooler has 2 apache black fans in push pull running at 1100 rpm and the pump is running at 4400 rpm. These temps seem to be on the high side.
