Solving heating 65 W fast charger that exceeds 44°C

The new 65 W fast charger does charged my Samsung Galaxy A34 phone within 1 hour 18 minutes from 31% to full charged 100%. However I do notice it becomes very hot before my phone get to full charged. I turn it off when the temperature exceeds 44°C. Despite only use 1 unit USB-C port from the available 2 unit USB-C ports and 1 unit USB port. After tell a friend about it, using a fan to cool the charger down is one of the suggested solution. This would not void its warranty. I do check with my thermometer. The charger temperature did not exceed 40°C with fan turn on. To be exact between 34°C to 37°C. Without the fan turn on, the charger temperature easily reached 44°C upon 10 minutes usage of only 1 USB-C port used.

The cooling set up that I used at home with this  65 W fast charger.

With this setup, there is no issue of temperature to the 65 W fast charger exceeds 44°C. Despite all 2 unit USB-C ports and 1 unit USB port occupied. For duration more than 2 hours. At least I do not have to return the bought 65 W fast charger. And it does works well to fast charging my Samsung Galaxy A34 phone. As with the previous 65 W fast charger, it takes 1 hour 50 minutes from 30% to full charged 100%.
Until then, have fun in solving your heating 65 W fast charger.
