    Upgraded my system's BIOS, now my fans make a racket!

    My current PC uses a Gigabyte GA-G33M-DS2R and during my spring clean today, I figured why not do a BIOS upgrade whilst I'm at it.

    The upgrade itself went smooth enough, the PC is now running BIOS v8b, the latest. However, my PC is now a lot louder than it was originally - it's very annoying!

    I built the PC to be quiet (well, quieter than my last one). It's got a Corsair 520W HX PSU, a Scythe Mini Ninja Cooler, and a passively cooled 2600 PRO GPU - all quiet.

    The Antec NSK2480 case has two fans, but I've opened the PC up and they're both set to their lowest speed and don't make much noise. The problem therefore has to be the CPU fan, this BIOS upgrade seems to have made the fan quicker, and louder, but there doesn't seem to be an option in the BIOS to change the speed of that fan...?

    Can anybody suggest an app that'll let me adjust the CPU fan speed, or an alternative workaround? I've only been on the PC 10 minutes since the upgrade, noise is driving me nuts already.

    nothing in pc health options to change this? if auto doesnt work then there should be a voltage option from what i read on a quick google, and your not alone it does seem to go to 100% with the bios upgrade.

    Make sure your motherboards fan controller is not set to maximum, most motherboards have either a temperature control or an option, on some motherboards I believe it's called QFanControl.

    Unless you did the bios upgrade to fix a particular problem (or it offers other facilities useful to you) the simplest solution would be to revert back to the previous version. (If it ain't broke - don't fix it!)

    Thanks GoNz0, that was spot on. There was an option to set the fan to Voltage as opposed to Auto. I've done that and voila, quietness has been restored.

    keep your eye on the temps then as it may still warrant you rolling back to the older bios to get auto fan speed back if it gets hot in game ?

    Check all settings in bios, upgrade defaults absolutely everything, lost all my custom settings that way and forgot to write them down...arg!!! There could be more than just fans reset.
