Hello everyone,

I got an Intel X520 10G NIC for my Cisco Server. I checked the compatibility beforehand and this one was mentioned as compatible. After installing it, the fans are always blazing which is super annoying. Do only Cisco branded X520s work with Cisco servers with proper heat policies or generic Intel X520 should work as well? Has someone used this setup and not have the fans running all the time? What are the possible solutions other than getting a Cisco card?

Thanks,
