After 5 year my Asetek water cooler died. Fortunately the system shut down without burning up anything important. I managed to find an old, fairly efficient, air cooler in my parts locker and after a long search managed to find the original amd cpu cooler hold downs. Back up and running. This cpu mostly feeds 5 antminers and 2 7970's, so having it back up gives the team about 5 million per day. I really need to organize all my hardware parts!
