Works flawlessly
At max RPM it’s managed to keep the Epyc 7532 at a max of 43c in a 22c ambient room with poor airflow. At about 1000 RPM it maxes at 55c this test was done under full load. Attaching the cooler to the brackets isn’t like the usual consumer grade coolers, make sure you attach the brackets to the cooler first and the screws get screwed in from underneath to keep the bracket in place or at least for the AMD side of things. I tried attaching the brackets to the board and cooler after the fact and well, it was a lesson learned. Impressive cooler for impressive value. I was going to add my P12 Max fans to this but the fans that come with the cooler are more than adequate.

Quiet, cool temperatures
Using it to cool a 64 core Epyc socket SP3. The cooler is quiet and keeps the temperature of the CPU to a reasonable level. Fitting is releatively easy but you have to follow the instructions as everything needs to be positioned correctly depending on the exact setup you have. There is also an order required to tighten everything down to make sure that you get good, strong contact with the CPU, but everything is well shown in the instructions.
