That's because the "other" demanding software isn't as demanding or not as efficient at utilizing the resources available to it. The only software I have run into that is similar in cpu use is Handbrake for converting videos.

Downloading is not that demanding but converting the downloaded rss to epub will utilize all the cpu available to accomplish the job.

Calibre only stresses the cpu during the conversion process, the rest of the time it is quiet. My concern during these big cpu load times is calibre preventing me from doing other things at the same time. To prevent this I went to Preferences - Behavior and changed Job priority from Normal to Low.

Additionally you can limit the number of conversion/news download jobs happening at once and limit cpu cores used by going to Preferences - Miscellaneous. Limiting the jobs / cpu cores can keep the cpu cooler, but it will take longer.
