I was just wondering, everytime I click a treasure and the hero set showcase shows, my GPU's fan goes crazy (I don't even know if it's my fans, it's like an low buzzing electrical noise), I'm using MSI GTX760, if anyone is wondering.

Does anybody have the same problem?

Edit: Just opened MSI afterburner to look at my GPU's condition, it seems like my GPU usage goes to 100%. Is this normal?
