Question I purchased an A2SDI motherboard and I want to change the heat sink to a passive / active one. Can I purchase this heat sink separately? Answer This is possible, see the below part numbers. Please be aware that changing the heat sink voids your warranty, only do this if you really have to. Active heat sink PN: SNK-C0057A4L Passive heat sink PN: SNK-C0054L Was this FAQ helpful?
