We are actively seeking ready-made 80mm pin fin heatsinks, ideally with a height ranging from 40mm to 60mm. We are open to using either aluminum or red copper materials. Additionally, we would like to explore options for larger heatsinks that can comfortably fit within a footprint of 245mm x 177mm. Could you please provide us with a selection of available options that meet these criteria? We're eager to review your offerings and discuss potential quantities. Thanks for your assistance!
