Hello, I have a Thunderbolt 2 PCIe enclosure for a card I need to use from time to time. I can live without the fan noise when I'm not using it, and I was wondering if it was OK to just unplug the TB cable when not in use. The device doesn't have a power switch. I'm asking because hot-swapping PCIe cards is not what they told us in school, but this interface is different... Thanks for your help.
