Hey all,

I got a OWC 10GBE Thunderbolt adapter that gets extremely warm when I'm transferring large amounts of data.

Now, I been considering the OWC Thunderbolt Pro Dock, as I could do with a dock, but, I must admit it would bother me a bit to have a large device like the dock on my desktop that was super warm to the touch.

So, question, does anybody here have the OWC Thunderbolt Pro Dock, and are using the 10GBE? If so, does it get burning hot like most of the thunderbolt 10GBE ethernet adapters?

First generation 10g device get hot, it was that way back when ^ first came on scene, the first generation ns became hot put the second generation worked without getting hot! So you can expect that as first generation 10G device comes online, that's the price you pay buying first generation devices!

I had and tried it - yes it does get warm when transferring at 10Gbe. It’s just the nature of the beat. Most 10GBe adapters are large with heat sinks to cater for the heat…… personally I didn’t have any issues with it though, but bear in mind it does come with a cooling fan so isn’t completely Solent (although you can switch the fan off, but its recommended to leave it on…)
