Asus 390 card gets hot while watching youtube vids

Just as the title suggests, my card gets hotter than I think it should be getting. Usually while I'm gaming, I'll see my temperature range from 66-72 degrees celsius. Which is manageable, I've tweaked my fan speeds accordingly while using MSI Afterburner. But what seems strange is that while watching youtube videos, I'll see the very same temperatures. Is this normal for a card to do? I know the Asus brand 390 has some cooling issues, but I didn't think that it would have to work very hard for youtube. And I'm not even talking 1080p videos, but just 480p.
