Please, Gigabyte, add the ability to trigger chassis fans speed from CPU temperature. Currently they are tied to system temp only. Mine doesn't change much idle and under load, it stays around 35-40 °C so the exhaust fans tuned for silence do not provide enough blow when under load and I get CPU overheated. If I adjust them for performance they're too noisy while idle. So the current control scheme where the chassis fans are triggered from system temp is pretty much useless in my situation.
Speedfan software in general has the ability to trigger fan curves from anything but it doesn't recognize the ITE IT8628E chip installed in latest Gigabyte Z170 motherboards like GA-Z170-HD3 I have.

So, please either add more flexible controls to the fan section of SIV or provide the Speedfan author technical details so that he could add support to your latest mobos.
