laptops motherboard isn’t showing sensors for the vrm
what are you using to determine temperatures?
HWinfo will usually show a lot more information related to onboard sensors than most other system statistics software, even those available from the actual manufacturer.
I would just like to know if the vrm got too hot, it would thermal throttle instead of cooking itself.
i would doubt there are many, if any, here that have actually disassembled this exact model.
or that have worked in it's design that would know it's onboard software routines for regulating temperature.
you should try searching for the specific motherboard or possibly the laptop model + board in Google Image Search or something similar.
this way you could see if there is any adequate VRM heatsinks or mini fans for them.
for tech data about the board you should try contacting Acer tech support.
though it may be difficult to find someone that could/would be able to tell you much.
