hi there again!i have another technical question?i own an xpc shuttle and bought an ati 4870hd (overclocked edition)not installed yet!as i understand heat is an big issue with powerful gpu's!my question is to owners of this particulare card!when the card is installed does the airflow created by the fan of the card,go from the inside out?or from the outside into the computer case?i am putting an xtra 92mm fan in to case to create enough airflow to keep this bad boy cool!
