Event Organization Overclocking
In the last ten years I attended several times at Austria's biggest gaming called Game City. Together with partners like ASUS, Intel and DiTech (biggest hardware retailer back then) we showed liquid nitrogen cooled systems on the main stage of the event. Our goal was to bring the interest of PC components back to a younger audience.
The biggest challenge of these type of events was to solve numerous problems with a very unstable, highly overclocked system while talking to the audience to keep them entertained even when everything went wrong. Nevertheless we achieved lots of Top 10 world records and national bests live on stage.
