We compared temps - and consistently the 335is was running at least 10f or more degrees cooler. I used to have one of the early 335 e92s - and the 335is definitely seems more at home on the track. From my view of the world BMW did a pretty good job with the extra radiator, duct work, etc. on the IS.
The 335I needs to read his code. If you take the time to read this thread, you will learn that temps are almost never the reason why the car goes into limp mode.
I'm glad your 335IS is holding up for you. It's performance is probably due to the overall newness of your car. The 335IS is unfortunately a poor track car IMHO, because unlike the M3, the DCT, has no tranny cooler, and the car shuts it down when the tranny temps get too high.
