Customer Reviews
Customer Review: “This product is exactly what it should be—a straightforward, properly featured adapter. It even comes with an adequate heatsink and thermal pad to ensure good thermal transfers. This isn’t really important, but it’s nice to see for situations with inadequate cooling like SFF builds or servers.”
Customer Review: “This is a great product that comes with a heat-conducting thermal pad and a heat sink. It’s plug and play—works like a charm. Do note that this uses a PCIe x4, so make sure you either have a spare PCIe x16 (basically the graphics card size) or something 1/4th of the size.”
