keep in mind the V runs hotter than normal by design.
the CPU runs at 7W instead of the standard 4.5W (still within intel’s specs, 7W is an option, i think they are 3W, 4.5W and 7W), and the intel dptf (something something thermal framework) thermal limits were adjusted to accommodate this. as a result, it is not unusual for the V to feel hotter than what you might be used to with other devices.
nothing to worry about as it is very unlikely that the V is overheating, there are many things in place to throttle the processor before it even reaches the point where that would happen.
one good thing about the chassis of the V being the part of the cooling solution where heat is dissipated is that we have a 100% definite indicator of failure: if you get burned on contact, that means the chassis is at >60C - something is up frickin CALL THE FIRE BRIGADE
then send an email to eve for warranty replacement.
do the above in the specified order for maximum safety. or do whatever if you’re a badass.
Ubuntu should be perfectly OK if your purpose is just to try and determine if its hardware or a Windows issue.
I can confirm that Ubuntu on a USB boots and runs perfectly OK on my V. Only issue is it might give you a neckache because the gyro seems to think the V is on its side.
…unless you’re smarter than me and it doesn’t take you forever to figure out how to rotate the screen, I suppose.
