Coldness of vape is a factor of amount of vapor, amount of air, and distance between coil and mouth. To get a cold vape play with these parameters.
If you like a big amount of vapor you have to provide it with a lot of air to make it cold and/or use a long drip tip. If you don't mind the vapor make it less by building a smaller coil with the same power(also this allows more air around the coil)
What steliosss mentioned above is valid. He gives you practical measures to play with these parameters as well.
