There are very few people in Viet Nam who complain that the coffee or the climate isn't hot enough. I have my doubts slow drip/condensed milk coffee was ever intended to be served piping hot - just thinking out loud here. I do know that, after a year in country, when the temp dips below 75* you go looking for a lined parka or you start shivering.

To Americanize, consider using a very thick mug, preheated with boiling water. Create a terry-towel "cozy" wrap for the Viet filter and mug during drippage. That'll hot things up. Or put the mug in the microwave for 20-seconds after the brew is done.
