Q: 5. Where's the fan sound? Ive been using this unit for 3 days and feels a little hot, but the fan doesnt start. Also I connected my 2nd display to the TB port of this unit and doesn't work... Am I missing something?

A: Just turned on my 8TB G-RAID TB. There is a startup sound, then it has only a very faint sound, which I assume is the fan but I'm not really sure. I searched the G-Tech support pages but couldn't find anything specific to the G-RAID fan. There was something about another model, G-Safe, having a fan that only comes on when the drive overheats. But I don't know if that applies to the G-RAID too. I have a vague memory that my drive case sometimes feels a little warm and maybe reading somewhere that that's OK. But if yours feels really hot, you might want to just return it and ask to exchange it for another one. Also, do you have at least 4 inches of free space around all sides of the drive? I think that's supposed to be especially important in the rear, in terms of good ventilation.

Q: 8. what version of thunderbolt cable comes with? Thunderbolt cable 1 or 2 ?

A: Unless they have changed the design, this is a thunderbolt 1 device which comes with a thunderbolt 1 cable. The fact that is thunderbolt 1 vs. 2 is a non-issue because you're limited (even with a fast raid set up) by the speed of the internal non-SSD hard drives, which though 7200, perform at a speed much less than possible through thunderbolt 1 technology. That being said, I own five of these drives and like them very much.
