Is it totally dead? Or is it some kind of life in it?
Are you sure the powersupply is OK?

I dont get any lights, nothing! I thought when they hit 80 they shut down for safety not completely!

What happened, when I set the room up the door closed and before I noticed they room over heated and that miner shut down.

First make sure the powersupply is ok.
If it's totally dead, no fans or nothing i would suspect the psu. There might be a thermal protection inside the PSU.

Are you able to measure the PSU in any way? Disconnect everything, and connect a fan to it?

I don't have any special knowledge about the S4, but i suspect it's pretty much the same as S6.

90% chance you hosed the psu .

I think you said you had more s4's

I have no idea if you skills at tearing down gear.

If you are up to the task of pulling 1 psu from a working s4 to put in the dead s4 if the dead s4 work you are certain you need a psu.

Also OP before running again if your getting this hot to cause damage.... work on cooling.  I would not run again if you know it is hot to the point it will damage miner's. 

I think you need to do this for the 9 others.  As if problem is still there you chances will have it happen again.   But I hope it was just PSU.   Might open it up and see if visible damage due to heat on anything.
