I have a Sapphire RX580 Nitro+ SE. This is a blower style card, and when the fans spin up, hot air naturally comes out of the back, which is expected. However, the other day when I was messing around with my fan setup, I had my side panel off while running Heaven benchmark, and hot air was noticeably coming out the front of the card towards the front of the case. I'm assuming it was intentionally designed this way, but it seems to be self-defeating as this card runs warm and the air being blown back into the front of the case was rather toasty. It follows that my case fan setup should take care of this through intake and exhaust, but it just seems like a sub-optimal design. What are your guys' thoughts?
