Make it cooler varakunai. I know mine was cool even when the LCD was flashing, but if you look in your mining stats page for that unit, you will see that 1 ship chip on 1 blade is probably hot. That's the case for me and there isn't much you can do about it besides try to get it cooler or just have the LCD blink until Cheshyr can get some new blades in. Hopefully more of an annoyance more than any real danger in frying the blade. I can't have 2 blades die on me!!
