fan spinning out of controll

Quick Question??!!
95 S-10 2.2L I have replaced at least 4 fan clutches. 3 under warrenty. Last one cost me about an arm and a leg. Here's the deal I shut the engine off fan keeps spinning. How dangerous is this? I have heard everything from "no big deal" to "the fan will shoot threw the hood" Anyone else have this problem????

I've never heard of that many fan clutches giving anyone problems. I would almost say it's just bad luck. I had a simular problem with starters on my daily driver (about 8 on warenty, 3 didn't work when they were installed)
However I'd be tempted to just remove the fan and install an electric fan instead.

I wouldn't call it no big deal, if it's spining like that after you shut the truck off it probably doesn't have the force to pull air through the rad when required.
I don't think that it'll fly through the hood unless the fan clutch actually breaks apart.

Switch to an e-fan and be done with it..

thanx guys! I'm not overheating yet(summer oh crap) any other info would be great!!!!
