Kind of worried that it's at 67c at idle. It's in a corsair 550d with lots of fan and the side and top panels popped open so ventilation is not a problem.
The 290's are known to run hot , since your temps under load don't go too high it appears to be normal.
Adjust the cards fan curve using MSI Afterburner if you would like to drop the temps more , but the card will get louder.
