I have two 280x cards, 2 brands running at the same time, one of them is MSI and the other one is VTX3D.
I'm struggling to get right settings for cgminer, both cards are hitting about 720 kh's but VTX3d is overheating (84 degrees)

I will give 500 blacks to someone if you can supply me with cgminer settings which will run both of these cards really cool (no more than 73 degrees) and they have to be QUIET. Both of them must be hitting atleast 705 khs stable.

./cgminer.exe --scrypt -o (yourpool) -u (user) -p (password) -I 13 -g 2 --thread-concurrency 8193 --gpu-engine 1050 --gpu-memclock 1500 --temp-target 73 --auto-fan

You must undervolt your card to 1.075V using a modded bios to achieve these temps.
Take a look at cryptobadger's guide or search the forums for undervolting guides.

Also, there might be an optimized bios for your cards on this thread: hxxps://litecointalk.org/index.php?topic=12369.0
