Physical: compatible with black Barrow radiators (I connect 2 of those black ones with 2 of those silver ones for 4 DIMMs). However, screws differ in the head, so be aware that you cannot mix two different colored screws doing the same thing. Black Barrow screws will not sink into these clones. From the seller's point of view: I ordered 2 of these at the same time from the same offer. But they sent 1 piece from different parts of USA. One came today and the second won't come for a week. Come on . Indeed? This is the last part I need and I have to remove the huge radiator to install it which means thermal paste etc. Also: Unlike the black Barrow brands, they don't seem to have screws that go on top to install the water block. They have holes and proper threads to carry the Barrow water block. It would be useful to have those 2 modding screws even without installing a water block. But that doesn't matter, since you only need different screws for assembly. Just nice to have. You're probably pretty good at getting the screws.
