different configs for same cards

[tins]

I have three 270x cards in my miner. The middle one is too close to the first and no room to move it. So, it is running 20 degrees hotter than the other two cards causing the miner to shut down.
How do I change the config on just the middle card? In the batch file, instead of just a single config that they all run at, do I make 3 different ones using commas?
What setting should I turn the middle card down to? I basically needs to barely run.

could you try moving or adding more case fans to blow directly across the narrow gap between the cards?  sometimes its just tuning the airflow and removing that hot air.  

also, e.g. -I 18,17,18 -w 256,256,256 -g 1,1,1  --gpu-engine 1050,1040,1050 --gpu-memblock 1500,1400,1500 --gpu-powertune 20,18,20

I would try using --auto-gpu and setting problem card with a range of engine speeds so it throttles engine down. Best way to lower heat in my situation for problem cards.  I use conf file for settings but can be done in bat file as well. I use "500-1000" for gpu engine speed.

Think I'll try that. I did switch to 1050,1000,1050 but it is still running hot. Going to try 1050,500-1000,1050
Also, put another fan on it as kalus suggested.

the --auto-gpu is essential for the range to work. Let me know if it works.

You have also to lower the clock of the cards, changing the intensity doesn't help that much.
