Dell Dimension 4600 - Processor Fan

All,

       I had to post this while it was fresh in my memory. I have a Dell Dimension 4600 that is about 18 months old. This system is out of warranty. The system recently developed a soft clicking sound that was intermittent. After searching through the forums I determined that the sound was either coming from the processor fan or the power supply. I removed the side panel and listened to see which device was causing the sound. I determined that the processor fan was the culprit. I found the Dell Spare Parts number and called about a half hour ago. After explaining my situation the Dell person felt that the clicking sound could also be coming from the hard drive. I explained the steps that I took to determine the issue but Dell insisted on transferring me to technical support. After waiting for 15 minutes I decided to hang up. All I wanted to do was buy a new fan. I told Dell that the fan was what I wanted and was willing to take the chance that I could be wrong in my diagnosis. At this point I will go a different route to get a fan. Thanks for allowing me to vent and any comments would be appreciated.
