To offer a better comparison than the stock cooler I’ve also tested an Arctic Cooling S1. The Arctic Cooling S1 offers similar performance but with a lower build quality and a larger footprint. On all of my heatsinks I’ve switched from the Thermalright Chill Factor to Arctic Silver Ceramique, my TIM of choice.
No surprise there, with a better thermal paste the T-Rad2 performs even better with a higher quality thermal paste. To switch things up I included my Arctic Cooling S1 which has been my cooler of choice for years. Looking over the numbers it looks like past 825MHz the Arctic Cooling S1 starts to fail while the superior quality of the T-Rad2 starts to make up some ground.
