I own a TwinFrozr r9 290 and the card is great so far. Playing games like Witcher 2, FC3. COD:Ghosts all on max 60 fps no problem. Temps at full load is typically at 65-67c and this is with my case fans running 50% and ac turned off in a tropical climate. Build quality is awesome and the card comes with a backplate so thats a plus.
Generally though you can't go wrong with the Twinfrozr or Tri-X. Both are great cards from reliable companies. Really I would go with whichever is cheaper.
Listen i have 2 MSI 290x Twin Frozr cards and mine regularly hit the peak 95* limit. whats REALLY annoying is that i did the reserach and went ahead and sold off my reference 290x then bought 2 MSI twin frozr OCd edition 290x cards because the cooling was supposed to be superb. NO IT IS NOT. is it just my cards??? thermal past bad? or what?
I don't know. But you can try putting a 120mm fan on your case pulling air from the outside directly onto and between the length of the cards. I think with crossfire that maybe they are so close together it is causing some heat build up or something. I had to use this method with my old 5870HD's in crossfire.
Thats the issue though :/... i justdropped 150$ on a new CASE Corsair 500R with 2 140MM Cougar fans. and there was absolutely no temperature difference! its beyond upsetting
I have a total of 8 fans. 2 140s on the side directly over the GPU / 2 front/ 2 top/ 1 bottom / 1 back
I feel for you bro, nothing worse then spending big money and then finding out you have been lied to by a manufacturer. Is it to late to send them back? Also, do you have the case in a small room or cupboard or something, I don;t think your cards should be generating the max amount of heat unless the room ambient temp is high.
One other thing, I'm not sure but a 140 mm fan may not produce as much air pressure as a 120mm fan. (Looking at a picture of your case, it looks like a 200mm fan?) You want a high air pressure and speed so the out side air is blowing directly between both the cards and forcing cooler air in there. A lower pressure fan will take air into the case but barely push it any further. So although you should not have to spend a penny more you may have to invest in a higher then normal pressure fan.
Also the 2 fans at the front of the case should be be pulling in plenty of air, are they definitely working? On my Coolmaster HAF case I didn't realize the front fan was not working until I'd been using the case for about 4 months!
Try a smoke test, use an incense stick or something and what where the smoke goes, you may spot 'dead' areas where there is no air movement. Ideally you want smoke matches:-

They create a lot of visible smoke. If you have any friends that are gasmen then they might have a spare.
One other thing, if you are getting frame rates of a minimum of 70 try limiting your FPS, like if you are using a 60Hz monitor then switch on V-sync so you get smooth game play AND then your cards are not heating up vreating extra frames you will never see. On warthunder I get about 200fps, but I use a 60Hz monitor and switched on V-sync (I chose the variable optiion) and I get a much smother experience then at 200+ fps!
