I was freaking out to say the least, I'm in the middle of developing my new site (sociallyhot.com). I tried every plug for hours until at abut 3 oclock in the morning it booted up.
Well, a non-function CPU fan will definitaly cause the CPU to overheat and give your PC some major problems.
Yes, on mission critical units(like my development unit) I use a RAID with two hard drives. If one drive craps on me I can Hot Pop another one in while never going down. The CPU Fan is replaced by a over sized heat sink this way you never have the problem of the fan going down. But make sure you use the right size heat sink. Elray
Be very careful using a air compressor!!!! I use one but I have a $200 Dyer unit with it. A compressor without a dryer unit can cause big damage to suffice mount components because of water and oils in the lines. When you buy Canned Air you are buying Dry air. Elray
