I have an Asus x550LD bought last June 2014. At idle (browsing) CPU normally range from 48-51celcius same with the GPU while HDD is 37-39. When in game (Dota 2) it usually goes up to CPU/GPU 65-69 and HDD is 41-44. I don't have air condition in my room but I do have a cooling fan, also I live in a tropical country. Processor is i5-4200 and GPU is NVIDIA 820M.
