you don't need 16GB of RAM unless you're doing multiple video renders or using CADCAM or stuff like that, 8GB is more than enough, all laptops have a cooling system, if you don't think the regular one is sufficient then get thermal paste and apply even more, or buy a cooling stand.
right india throws a major in the works, since there's no decent laptop seller I know of for India, so you're going to have to look into importing a much weaker laptop, even the y510p may be out of your price range.
