Cooling is regular Antec H2O 920, it fits into case without any problem. It took about 3 hours to assemble and overclock, I just followed manual. It runs 24/7, I do number crunching and Scala developing (slow compiler). Intel does not bother soldering heatsink into chip anymore (saves 50 cents). So newer CPU can not be overclocked without disassembling and replacing some parts. Results are not bad, but in reality it is just 30% speedup.
