R9 270X Idle & Load Temps

Hey everyone, I quite recently purchased 2 R9 270X's and put them in crossfire, they are both running at X8 mode, with a 750W PSU; and I'm slightly worried about the temps/cooling.

When Idling the cards start out at around 30°c, and then it begins to climb; the highest I've seen while monitoring at idle is 49°c. I ran ungine valley for around 30 minutes the other day to test out load temps and stability, and when I ran that it just kept climbing until it reached 76°c; if I left it on it would have kept on rising. At Christmas I'm switching back to a single card configuration with a single 780ti, however I'm selling the 2 270X's to 2 of my friends to get half of the money; so I really need to keep them running well. I know these cards can keep on running up into the high 90's but I want to keep them as cool as possible.

I'm going to do some tests tonight with some actual games, but if anyone could give me any insight into the temps I should be getting; that would be really helpful.

What are the brands of your Cards? I usually limit my GPU temps until 70~75C at maximum. I often get 67~69C. It also depends on your ambient temperature.

The cards are MSI, I think that my case has terrible airflow as my previous case ran the cards fine at around 35°c constantly. I have 2 case fans at the front blowing inwards, then 1 at the top as an extraction fan; also I have a h80i with 2 fans mounted at the back for cooling my CPU. Any help would be appreciated.

You mean "exhaust fans" :)  have you done overclocking? You have mentioned that you checked for stability so I assume that you do Overclocking. If you do, then you clearly have an unstable overclock settings.

My CPU is overclocked, and perfectly stable as I tested it on prime95 on the weekend for around 12 hours. And my graphics cards are at stock frequency, which is why I can't understand why they're overheating?

Check the airflow in your case.

I'm an idiot I had my exhaust fan facing the wrong way around, so It was blowing air back into the case instead of extracting it. Anyway, now my top card is running at around 40°c at idle with the second card at 32°c idle. and under load the top card goes around 80°c max with the second going around 75°c.
