yeah, after a day at work and a few painkillers i am a bit more aware of what i am typing. i usually do use fan guards, and a smart fan going wrong sounds like someone feeding rocks into a jet turbine engine (thats alot of fun actually, RAF testing++ ). however it didnt sound like normal, it had a more intermitant sound, just a clack-clack once every 20-30 seconds or so. i am *very* carefull of where i put my fingers in my computers, about 6 years ago i did stupid things like that, testing to see if the fan is okay by touching the blades or middle, and got a few blackened fingernails becouse of it, but i darent do it with these new high power fans, or my 240vac's. anyway, i grabbed hold of the outer case of the fan, and gave it a slight wiggle just to make sure it was not screws that had fallen out, one had about 4 hours previouse, but it wasnt the problem. then as i went to get up and shut down the computer, and just as my hand drew level with the edge of the case, the hub and blades of the fan jumped out of the fan casing bounced off the inside top of the case and back down onto my finger that was just resting on the metal lip that the case slides into.

i found the missing bit, well... bits. where about 4 bades had spun and hit my finger it had sliced it first and then taken the big lump before it hit the nail and bounced away.

from now on, watercooling with dual redundant fans, with box guards around them.
