mbm and shutodown now do work in the event of fan failiure and the cpou reaching the shutdown temp that you configured, I tried it by setting the max temp to 60C and stopping the fan (before I went watercooled) and it shut down no probs, as already mentioned, a heatsnk cant just FALL OFF, lol most of the clips need a screwdriver to put it on in the first place, that article of toms is major BS, and A LOT of people are now scared to own and amd, I lost out on a system, I was to do for someone because of that, (I refused to make them a pentium out of principle!) A fan fail test would have been apropriate, but a heatsink falling off is bollox, ANYTHING on this earth will break if you use it in a way its not supposed to be used, in this case an athlon without a heatsink- a ferrari engine would die if you ran it without oil and water- whats the difference?
