Dell B110 (similar to 1100) CPU fan malfunction
My computer is a Dell Dimension B110 manufactured August 2005 and moderately used since December 2005. Until 2 days ago, the fan has worked fine. I will run my computer for 45 minutes, then the fan makes a funny sound. I put my hand behind it and felt warm air coming out of the CPU fan. I turned the computer off yesterday, popped the cover off, and felt some of the heat sink components. The CPU and another chip nearby with a heatsink were buring hot. The powerpack was warm, but not unusual. I felt the air from behind another similar computer (Dell Dimension 2400, from 2003) and behind the CPU fan the current was much stronger and after a few hours was still cool. I have carried the computer around to test some monitors recently, but I have not dropped it. There is no difference with the issue about whether the computer is under Windows XP, openSUSE 11.2, or openSUSE 11.3.
I would like to know what is the issue with the fan, what caused it, and how to fix it and/or replace it. Thanks! Figure a lot of you are IT guys that know a bit about hardweare.
