Never made Thai noodle salad and have seen it in many different orientations. For a cold asian noodle salad I recommend the Korean jap chae. Made with sweet potato ("glass") noodles and vegetables, it is a simple but delicious dish. I linked to a pretty good description and recipe that I eat cold. I like to add a little gochujang to it after serving because I'm addicted to the stuff.
Sorry I didn't have a better answer for you, but I hope you try it and like it anyway!
