page 99 seems to mention 950 as recomended. What do they run without drill bit options or are they required? I have my eroupters running without cooling and they are running at peak.

I tried to run cooling over the eroupters and it seemed to interfere with them (maybe magnetically?) ,so I just leave them as is. I'll have to hope the boards run at a decent temp though I've got a fan ready to try and place when they get here.
