System has two extra 3 tb hdds, a Corsair 600w psu, an r9 380x gpu, and I swapped out the stock motherboard, ram and processor for an Asrock H170M, G Skill 16 gb ddr4 2133mhz ram, and an intel i5 6600.

Now, I was able to lower the fan speeds for my 3 pin header back chassis fan, and the stock cpu fan for the 6600. My question is: What are good settings for me to set the fans at? The motherboard's settings are a bit robust, so Im happy for that. I am able to set the fan speed by percentage based on the temperatures. There are 5 temperatures you can scale up or down. So, what should my settings be at to avoid overheating, and having it super loud too often?

If your smart fan tool can set 5 different speed for 3 pin fans meaning those fans are DC regulated (has various voltage range from 12V 10V 8V 6V) you can confirmed that by looking at the fan's sticker. I wouldn't recommend low speed for CPU cooler, for that I can only suggest you to

  • ■ Get Fractal design fan, the particular blade design make them suck air better than static pressure and high flow fans. Use this for exhaust fan at rear or top.
    ■ Clear the front/bottom intake fans from obstructions such as clattered cables, look at the arrow sign on the fans's frame, point them upward if they are front, and backward if they are bottom.
    ■ Get sense with your fingers, run your system at high load such as 3D gaming for a 15 minutes...

    ■ Get sense with your fingers, run your system at high load such as 3D gaming for a 15 minutes, these area are suppose to get air flow : surrounding PCIe slots (heat from R9 380 ought to be moved by intake fan) and CPU socket (heat from 6600 ought to be exhausted by out take fan).
