    They have stock of what I needed. They seem to be the only ones out there to have this cable. Price was good, shipping was free. What is not to like?

    I hear this stuff is pretty good, came on the Lenovo Legion 7i pro with the i9 ultra and the 5090 think I might try it on my forehead to get better telepathy thermals.
