I have had 6 different pc's in 6 years, maybe lucky as heck but never lost a hard drive, mobo, vid card etc due to failure. But those dam fans are so cheap and small they seem to have a rather short life. Cpu fan failed ystrdy in a box that i just installed a new hard drive (WD raptor 10k , 74g ). Scared me in thinking the new drive crapped out. HA This is another reason why the next box will be equipped with xeon "Woodcrest" dual FANLESS chips. Motherboard will be without a fan on NB chips etc. ... For the older boxes i guess it might be a good idea to now and then drip in a drop or two of sewing machine oil into the fans.
