Review on GLOTRENDS 2 in 1 M.2 PCIe NVMe 4.0/3.0 Adapter: High-Speed EMI-Protected Cover with Fan for M.2 PCIe SSDs and M.2 NGFF SATA SSDs by Gin Bajema

Pretty clever. Too bad it was dual PCIe NVMe. (One uses SATA, the other is PCIe) Turns out my phone had two m.2 slots, which I thought was great until I realized that one of SATA ports 5 and 6 was disabled, ie I got him to replace that slot as I have 6 hard drives that all need to be used. This PCIe m.2 adapter helped me run two m.2 SSDs without sacrificing SATA ports. I don't know if a small fan really does much, but I think it's better than no fan. In general, it's worth the pennies I've invested in it.
