This is something that has always bugged me - when I install a card into a desktop (ie mini tower) case, the fan is always facing down. Surely, making the card so the components and fan is on the top would help a lot with cooling, allowing those whiney fans to spin a little slower.
I know some card manufacturers tried to mitigate this by adding heat pipes and big heatsinks on the back of the card.. but they still put the bits on the same way as everyone else!
So, does anyone know why they're all upside-down?
Why would putting the fan on top help with cooling? We want the fan to suck in cool air and then get the air moving upwards as it gets hot. How can that happen if the fan's on top? – David Schwartz – 2014-10-24T00:57:16.687

1@gbjbaanb Right. So if the fan is at the top, you're fighting that. You want air to be moving up because it's getting hotter and hot air rises. A fan at the bottom can force air up. A fan at the top either has to force air down (bad because hot air rises) or suck air up (bad because it's much less efficient to suck air than to blow it). – David Schwartz – 2014-10-25T04:55:13.340
6Flip the case upside down (ditto the optical drives). Voilá, no more upside down graphics card :) P.S.: not all are upside down, many Dell computers feature the motherboard on the left hand side of the case, the result: no upside down graphics card. – None – 2010-02-21T00:08:44.680
They aren't upside down in BTX cases, from the hot-running Pentium 4 era. – paradroid – 2014-03-27T07:09:15.927
