I believe most medium to higher end coolers (and graphic cards) from well known brands use sintered heatpipes these days. But yes, you are right, you'll never know for sure unless you test it like I did.Or if you are lucky you can find some marketing stuff like that on the manufactures website:"Combined with grooved and copper powder sintered interfaces, the composite heatpipe design efficiently improve thermal transfer of heat between two solid interfaces and increase cooling capacity up to 30%"[URL unfurl="true"]https://www.asrock.com/Graphics-Card/AMD/Phantom%20Gaming%20X%20Radeon%20RX580%208G%20OC/index.asp[/URL]
