Interesting. I'm using the very top PCIe slot, nearest to the northbridge and CPU heatsink. Maybe some heat is dissipating from there, causing the card to idle at ~50C.

Do you think I should try a lower slot? I've got my sound card in the lowest slot so I may have to switch them around. I doubt I can use the slot at the very bottom because there is no room for the card. It's either middle or top PCIe slot with this case/motherboard.
