So I have a rx 580 8gb, plenty of power for video. It also has that whole fan stop when un-needed and a led fan stop lights up thing.

So for some reason, when using windows media player, ONLY WMP not any other player, even in 480p video, the card heats up enough to get the fans spinning.

What the •••• is WMP doing for ••••s sakes? I watch 4k in VLC and card is cool to the touch. Same in MPC.

Not important, Its not like it's hurting anything, but what the •••• are you doing little player?
