after 5 hours of overclocking with a 331 Celery we finally achieved a 5GHZ clock using an extreme Koolance water cooling system consisting of, an all important Koolance CPU 330 Block, two CHC-120 liquid cooling blocks for North and South Bridge cooling, and two Koolance VReg liquid cooling blocks.
The Koolance CPU 330 blocks ability to dissipate massive thermal loads allowed us to achieve temperatures around 40C while operating the core at 1.7Vcore
