Complete success, I downloaded a fan control app after I heard the grinding noise that I think most readers of this guide are familiar with. My fan was dropping into the 200rpm range and I had placed a box fan underneath the computer to keep the thing cool while I waited for the new fan unit to arrive. The guide was straightforward and pointed out a few of the problem areas that I might not have noticed without the prior heads up. The one addition that my IT friend pointed out to me is to make sure not to put the screws into the wrong holes during reassembly of step 5. There are two holes on either side of the DVI port and apparently once you mistakenly drop a screw into one of those holes its gone for good. Thank you so much, I could not have done this without this site.
