In September 2025, the nickel-plating process was switched to an electroplated bright-nickel method. As a result, the AM5 High Performance Heatspreaders of the 3rd generation now look similar to those of the 1st generation. The new batches using the updated process offer the same performance within measurement tolerance as the previously matte-nickel-plated High Performance Heatspreaders (2nd generation). At present, it is still possible that matte-nickel-plated High Performance Heatspreaders will be shipped. High Performance Heatspreaders with the original nickel plating (1st generation) should no longer be circulating in retail.

The same applies to the Mycro Direct-Die Pro water coolers. Here as well, the process has been changed to the electroplated bright-nickel method, meaning mixed inventory with matte-coated coolers may appear in retail. Performance has also not changed here within measurement tolerance.
