I just wanted to let everyone know that I found what was causing the fans to run at full speed. After going through the diagnostics....LED's and AHT with everything checking out fine, I found that I had a single pin from the hdd temp sensor cable that had somehow (by that I mean that I must have) been missed when I reconnected the plug. Everything is once again running smooth (and quiet.)
The fans were so loud that I didn't even want to use the computer. The fans were running around 2800rpm's and now they are spinning around 600rpm's. MUCH better!
