What kind of coolant liquid is used in acer switch 7 black edition?

Is it possibly aceton or something similar?

It is some kind of liquid with low boiling point. It smells a bit flammable, almost like acetone in the smell but it's not acetone.. I'm thinking if it's maybe 3m novec 649 or bestsolve Zulu. They both are non flammable liquids with boiling point of 49c.

My switch 7 touch screen and display broke and it's nearly impossible so find spare parts for switch 7 so I decided to make a tiny mini flat computer out of the mother board, but as you can see in the picture you shared the longer loop copper tubes going around the batteries are stretched far from mother board, so to make the computer smaller like half the size I cut the long tubes and shortened them to the exact size of the motherboard and soldered the copper tubes together to make a pc at exact size of mother board while being flat..

So i would need a low boiling liquid to inject into the copper tubing. And just today I stumbled upon novec and bestsolve. I think either of them will be perfect for my project.. Unfortunately it seems they only ship within US and need to contact them to buy, can't just order online..

Does anyone know of any alternative to these? A liquid with very low boiling point. Preferably non flammable.. Only one I can get my hands on is acetone with 56c boiling point but super flammable.. Was considereding using it since it's just incredibly small amount and in a closed environment inside the copper tubes.. But still don't feel it's a good choice if I can get my hands on something like novec 649.

Yeah I'm actually running it for the first time now after shrinking the tubes. Unfortunately a lot of the liquid was lost in the reconnecting of the tubes due to heat and the liquid boild out. Theres still a very very tiny amount left but next to none.. Surprisingly the pc is performing pretty much the same as the copper is slightly hotter, I'm having a hard time to tell differennce from before if it's truly hotter or not. I guess maybe a bit.. I'll smack some heatsink on it and that should be enough.. My idea is to go with 2mm heatsinks on each side. So the home build pc will still be very slim, probably just over 1cm thick but much smaller in length..

When ever I get opportunity to buy some novec 649 or Zulu I'll definitely fill the copper with it. I think it will even provide better cooling than the original liquid.. Gotta find someone from USA to buy it for me and then ship it to me since the company only ship within USA..
