Question Constant motherboard temperature

[Svalkash]

Hello.
ASRock Fatal1ty B450 gaming K4.
Checked in BIOS and in HWInfo - my motherboard's temperature is displayed constant (35C) even when stability test is running.
How to set up chassis coolers if I don't know anything about mobo temperature?
Is it better to control them using CPU temperature?

35C is nothing to be concerned with. So you can basically ignore it. Could be the sensor, like many sensors, is designed for the range where some action would be expected. It may only be accurate at higher temperatures.

Even when optimizing you will want to pick which components to concentrate on. CPU, CPU VRMs, GPU, not really much else in there that takes a lot of power.
