The "delete" key did nothing. F10 got me into the bios screens. In the bios screens there were tabs for Main, Advanced, Power, Boot, and Exit, and I looked at all of them. None of the screens mentioned anything about a fan, so I hit Escape and got out. So I guess I have no control over any fans. I did notice the other day when I had the case open that my PC has 2 fans. One fan is on the big block that cools the CPU. The other fan appears to suck in air from outside the case (or vs. versa). I cleaned out the dust from inside the case and the fans by use of a can of compressed air. I have not since heard the whining fan sound, but I expect that "fix" will be temporary.
You may have noticed that I posted another problem/question about my newly added Sabrent PCI USB3 2 port card running at almost USB2 speed. While I was in the bios today I listed the USB entries. A few low-numbered entries showed things like the USB mouse and the UPS, but most entries were empty. However I did notice that USB port 8 showed as "USB2.0-CRW Generic". Is that maybe why my new USB3 card is not running much faster than USB2? In Windows device manager I simply can't tell what's what under the list of USB stuff. Some are obvious, like the Logitec camera and the mouse, but other things don't appear to give a clue what they are.
