Review on UCTRONICS Raspberry Cooling Aluminum Heatsink by Michael Bustamante

To be honest, don't expect strong cooling. It works just as well as the larger single fan unit. The airflow from the fans only passes a few fins on the heatsink and is very short even then. Is it better than the fanless options? Yes. Much better? no I would probably use it in a case where the load is light but the fans help on a hot day in an industrial environment. Also, it's not a tool for the job. The metal that draws heat away from the chips might be a few thousandths closer to improve contact with the included thermal tape, but it definitely prevents your Pi from being used in normal environments like the office, living room or whatever with casual internet use overheated. , in standby mode or in streaming mode. Yes, and the fans are not silent, but it only counts when they are on the table next to you.
