not sure what you're talking about? I did say he goes on to describe the fan. However, some took his presentation to say that the device was fanless. I was just puzzled as to why he put that out there?
Here is more of the quote:
"
I can go through all 100 custom parts it took to do that. I won’t. I want to talk about one part. It’s probably the most significant of the parts. I’ll hold the device so you can continue to get a shot of it. But look at the fan that you see up there. We talk about fanless all the time. Fanless is an interesting concept. That was something people talked about three years ago when they talked about tablets.
This thing is fanless. Another way to say fanless is “thin.” Another way to say fanless is “cool” to the touch. Another way to say fanless is you don’t feel the air.
So what we designed in our product as you know from Surface Pro 2. Take a quick look at Surface Pro 3. Do you see that perimeter vent going around here? That same vent in Surface Pro 2, that same technology invented came into this small package.
Then we reinvented the fan. We were able to make it 30 percent more efficient than any fan in any product today. Then we reinvented the fin on the fan, and we’re able to radially emit air throughout the entire product so you never feel it. You don’t hear it. You don’t even see it.

I am Writing this on a SP3, So obviously I like it. I think it is important to point out real world usage us what is represented to make this and every version better. It also serves as a reminder to manufacturers that customers will really hold them to the verbiage that convinced them to part with $ 1200+ dollars.
