No matter WHAT you are doing, the lower end idle specs don't matter, at all, unless your maximum thermal response is not staying within specs.
And regardless of what you are doing, so long as your maximum CPU temperature does not exceed 85°C maximum under full load, and your graphics card does not exceed about 90°C, you should be fine. Those are the Intel and Nvidia thermal specifications for those components. Actually, for the GTX 1660 it's 93°C, but at 90° you can assume you have a problem of some kind.
