Closed. They do well in CrossFire / SLI when the cards are next to each other.
Closed. I'd rather the hot air be blown out of the case.
I'd have to agree with these replies.closed, just to get the heat from the system and not re-sucking it back in again.
Listen to this guy, he bolds his text so it must be true.The OP is misleading because it is not an either/or. There are some "open" (technically, axial) designs that cool WORSE than reference/closed designs, such as the XFX DD :

There is also a long history of non-reference cards using better or worse hardware than reference. Some custom cards are better than reference, while others skimp and use cheaper, worse parts, whether heatsinks or capacitors or worse voltage regulation or whatever.
If watercooling or crossfire, closed is often better (the former because reference is standardized; and crossfire with two open cards next to each other may be problematic depending on the spacing), else many open designs may be quieter or cooler depending on the design.
I also object to the "open" vs "closed" terminology. It is axial vs radial fans, not "open" or "closed."
As always cost is a factor so depending on how cards are priced and what the quality of the underlying GPU, memory, VRMs, PCB, etc., I can go either way. Axial vs radial fans is just one of many factors to consider.
I have nothing useful to say
Closed, i like the warm air to be blown out in winter, helps heat the room![]()
