I ran my other ones (EB edition 1.8v) @ 1800+ 1.9+v a few times....maybe I killed them.
EDIT: on the subject of the chiller....I have decided to rearrange and put the chiller/bench table in the center of the room instead of off in the corner/closet. It will make everything way easier....now that I have stood hunched in the closet working on it for 3 weeks
