Normally when I'm running encoding tasks on Handbrake it will use all 4 cores of my CPU at 100%, which is fast but obviously renders the computer somewhat unusable. With this in mind I've been messing with processor affinities in task manager and set handbrake only use 2 cores. All seems fine and dandy. 2 cores are at 100% usage, leaving the other 2 for everything else. However, I'm wondering whether this has any negative consequences? Is it safe or healthy for the CPU? Thinking of maybe even switching Handbrake to use 3 of the 4 available cores, but then there are only 2 physical cores, so I'm not sure the consequences of that.
