Yeah I can't imagine it being any good.
But I haven't tested it.

I suspect the cooling he experienced was mostly due to the airflow and not so much because of the peltier.
I have pic related VR strap with integrated fan.
It's just a simple fan, no cooling, but it makes a huge difference in how hot I get playing VR. - just having some airflow on your face does that.
