  Veriton 3900 PRO, fan is very noisy when I boot. I discovered if I hit DELETE to go into SET UP and then F10 to SAVE AND EXIT SET UP the fan speed drops to quiet. Any clues as to what bis happening here please?

    your BIOS version is R03-A4?

     

    it looks like an issue on BIOS, maybe a reset CMOS and load default settings, can help.

    @IronFly: 2007' model. Probably the Cmos battery is low or defective. Update random of the bios thermal module.

       Cmos battery looked promising, the installed one was very dead, but a replacement did not solve this problem. I guess my routine is only a couple more key taps on boot up.

    Hello,

     

    I would flash the bios R03-A4 under DOS.

       Hello laurent_14.    Started quietly at last boot up, so cmos battery may have been the problem.
