BIOS / H/W Monitor / CPU Fan Setting / Automatic
Default for the CPU fan is "Full On". My NAS has the same BIOS, and it sounded like the Goodyear blimp before I did that. You can set a target temp and speed level.

It's giving me an option to adjust target fan speed (Level 1 through 9 -- it's currently on 9 on automatic), which level should it be?Play around with it, but monitor your CPU temps. I think mine is set to 5. I believe that means that it will run at half speed until it needs to go faster to maintain the target temp you set. I set that at 50, if memory serves. But a NAS CPU does practically nothing, and it rarely goes above 45, anyway. Play with it. You don't want it going up and down all the time, because that would be even more annoying than a fan that is constantly a little loud.
If you want quiet, you have to pay. Generally speaking, the bigger the fan, the quieter it is, because it can spin slower and move the same amount of air. Heatsink design factors in, too, of course; a more efficient radiator will require less air. You can look at the decibel levels of a lot of popular coolers at Frostytech.
Thank you very much.
I'm not sure what the correct temperatures are.
