Thanks for all of the advice. I googled this issue but could never resolve it. I almost scrapped the desktop several times but didn't so it collected dust for several weeks.
I turned my attention instead to my current desktop that still has Win 7. I have been wanting to install Win 10 but it appears you cannot find a free legal way of obtaining that so I bought a downloadable copy for 25 bucks. I got it installed and really like it.
I was sent links to install Win 10 and and one link was to create a bootable usb for another PC so I created one. I thought I would try the USB to install Win 10 on the Dell 9020 with the fan issue.....figured it couldn't hurt to try.
I stuck a 2 TB hard drive and 20 gig of ram in it and the USB was successful installing Win 10.
It works great and no more fan issues. I know it's an older machine but it's a lot faster than any other I've ever owned.
