Review: Fan is quiet - I was concerned that the small fan on the card would be loud. I cannot even hear it in my OPNsense firewall situated in my Livingroom.
Review: I bought this network card to use in an OPNSense firewall/router machine i was building, I wanted to use one port on the NIC for 2.5gbe WAN and the rest for 2.5gbe LAN. I've been using this for a few days in my firewall and have had 0 problems since install, its been extremely stable. Before installing OPNSense on my machine, I tested the card out on windows and Ubuntu and it seemed to be working fine as well. I'm very satisfied with my purchase, i was reluctant at the lack of reviews but I've had a good experience so far, if anything changes I will update this review.

### ⭐⭐⭐⭐ Review
*by S***P on 19 September 2025*

Bought this to test with OPNSense. First time using it and setting up a router with my own hardware. I dropped this in an i7 4790, 16GB DDR3, 256GB NVME and this four port NIC. OPNSense detected without a problem and was up and running at 2.5gbps. I have a 2gig fiber connection and hasn’t given me any issues. I will note the card did not have a fan like the picture and does not have the option to add one. The heat sink is large enough that it shouldn’t be an issue but will tell with time. The model number received matches the pictures and one ordered so could be a different revision. I’m on the fence on returning this if heat is an issue since this is in an itx build with limited fans. Overall happy it with it.
