I have been told this in response to a problem I described to them involving one of the computer's fans intermittently making a lot of noise.
A tech support person told you to update the BIOS because of an intermittently noisy fan? You need to call back and get a different support rep as this one is obviously on drugs.
If the fan is bad (out of balance because of dust, worn bearings, blades hitting something) then a BIOS change will do absolutely nothing to fix the fan. However, we don't know what you mean by "intermittent noise". Could be when the CPU gets hot the fan speed gets increased to keep the CPU cool, and it is the increase fan speed that you claim is "noise". Fans spinning faster always make more noise. Monitor your CPU temperature to see if the "noise" appears when the CPU temperature reaches some threshold.
Although possible, I haven't see a BIOS that has variable speeds for the fans based on temperature. Instead it is probably some software that you load on Windows startup that monitors the CPU and case temperatures and will up the fan speed to keep temperatures from reaching critical and destructive levels.
If the "noise" increases with fan speed increases then that noise is normal. However, a fan with worn bearings, out-of balance blades, or smacking a wire with the blades will also make more noise as fan speed increases but there is additional noise beyond just the air turbulence. Hard to say what noise you are hearing but a BIOS upgrade won't fix it, anyway.
Due to the odd semantics of the missing "D" I can't tell if I turned system fan control on OR off, but I can tell you that I turned an annoying sound into a load roar. I have just reversed what I did and I am back to an annoying noise. The fan that got louder appears to be the large one connected to the shroud which is connected to the large heat sink, Even with the screwdriver trick I am not sure because the screwdriver appears to change the pitch of the sound.
In any case I agree with all that I can't see a BIOS update (preceded by a time-consuming recording of settings) as fixing this problem, a problem which seemed to have followed a technicians replacing a drive adjacent to a fan.
I think your advice is correct and I will have to bite the bullet and bring the machine. First I must convince Gateway to take it.
