    Dedicated 2.5GBASE-T SFP+ transceivers that run cooler than 10GBASE-T transceivers?

    My main switch (MikroTik CRS309-1G-8S+IN) is running very hot with 3 10GBASE-T SFP+ transceivers (even spaced in non-agacent ports). I did the popular fan mod but it was loud and only kept the closest port cool. I have a 10GBASE-T NAS, a 2.5GBASE-T WiFi Router (Multiple VLANS--untagged so it...

    10GbE NIC in PCIe 2.0 x1 (x16 slot), Will this cause problem?

    Hi everyone, I want to upgrade my custom build TrueNAS to 10GbE. However, I find that the motherboard only remain a PCIe 2.0 x1 (in x16 slot). I accept the low bandwidth (5GT/s) but I would like to know if the card will fail to work in that slot. Any recommendations are welcome :) Thank you.
