Earlier quoted context omitted.

For gaming or videos I actually can’t tell the difference between 4K and 1440p. For text rendering I absolutely can.

As an aside, many 4k/1440p videos are not really 4k or 1440p, vs how we would classify a 4k/1440p monitor. Video is mostly 4k/1440p light levels, but less than that w.r.t. color information. A common video subsampling setup is 4:2:0. https://en.wikipedia.org/wiki/Chroma_subsampling In addition, common video compression techniques (at least the simple ones that I could still understand) basically reconstruct blocks of…

I have my PC setup to be fanless for the majority of tasks, except for gaming pretty much. With a massive CPU heatsink I can tune fan profiles to only turn on when nearing a maximum temperature. I run the equipment fairly hot, in other words. My fan curve is just one giant step, with hysteresis so they don't cycle on and off near that step temp. I am likely trading some component lifetime for silence, but it's a trad…

I put downvolted fans that are inaudible on my passive setups. That way I get both silence and longevity. The added benefit that if the fan dies the hardware lives. My thumb rule for temperatures is if you can hold your finger on it indefinitely it's cool enough.
