Thoughts on Acer's self-contained passive Liquid Loop?

Acer uses this in some of their laptops, namely the Switch Alpha 12 and the Switch 7 Black Edition:

It's a fanless passive system that:

1. Acer LiquidLoop™ transfers heat from the CPU to the heat pipe via a thermal conductor.

2. The heat pipe then generates a single direction, two phase flow of liquid.

3. Heat is dissipated through a continual process of evaporation and condensation of the liquid.

From a science perspective, I feel this to be pretty dubious. Yes, thermal energy is definitely carried away from the source very efficiently through evaporation (like sweat on our bodies), but the heat energy still needs to go *somewhere*. In the case of the human body, evaporation transports the heat energy into the surrounding air. Evaporation of heat energy within Acer's LiquidLoop at best will simply go into the metal chassis of the case and slowly radiate outwards.

Basically the LiquidLoop, at least to me, is just a more efficient way of making the chassis into a passive heatsink. It's not actively transporting the heat energy out and away from the unit itself. If you surrounded the Acer tablet in a plastic/rubber protective case, for example, you would roast it.

Thoughts?
 
its a glorified heat pipe.

Personally id rather have real heat pipes, with active fans.
 
I want this on desktop. Implementation of this idea will open whole new world for passive computers.

to expensive on a PC solution unless u want a small tower like like unit to sit on top of the cpu.
Even then there are passive heat pipes already that do a fairly decient job not overclocked.

Of course the price tag on such units wont be to your liking tho, due to most of the cost being in heat pipes and the gas medium that is kept inside those pipes under low pressure to maintain a low boiling point.
 
But its, its... "superb performance, space-age cooling"!

Zalman used to make a case like this, TNN500AF.

The problem I've run into building semi-passive computers is cooling VRMs. On my latest 1800x rig I can totally get away without a fan on CPU itself, but unfortunately without CPU fan VRMs were getting so hot it would reboot. So I had to reluctantly add fan to CPU to get that airflow over VRMs.
