I am gonna use the following model of CYCLONE V FPGA (With device number 5CGXFC3B7U15C8N) and as I checked on the website for the values of the 6 thermal resistances (http://www.altera.com/support/devices/packaging/specifications/pkg-pin/dev-package-listing.jsp?device=cyclone_v), I found the following numbers: 

 

 

 

 

26.5 

223.3 

20.3 

18.6 

5.7 

11.0 

 

 

 

 

It was really impressive that the 2rd value (θ[sub]ja[/sub] (° c/w) at 100 ft./min.) is 10 times bigger than the first one (θ[sub]ja[/sub] (° c/w) still air) !!! An in comparison with the values of all the other models, I tend to think that there is a typo-mistake there (it is 23.3 and not 223.3). But is it possible to confirm that? 

 

Thank you very much in advance!

I would open a Service Request on this with Altera tech support.
