Undervolting CPU voids warranty?

I've just bought an Acer Aspire 7 (i5 7300hq + gtx 1050ti) and it generates a LOT of heat while playing games.
I should undervolt the CPU for less heat I think. 
But I DO not want to if it voids warranty.
What do you think?

    I don't think it should void the warranty, but I am not sure myself. Fortunately, there is no way for them to find out whether the CPU has been undervolted or not. A simple windows factory reset to the drive will clean this information.
    Always post the following characterisitcs of the device:
    -Model number
    -Part number(not required, but helpful)
    -CPU
    -GPU
    -Operating system

    Helios 300 and Nitro 5 users DO NOT update the BIOS to version 1.22 if you don't want the keyboard's backlight to turn off after 30 seconds even when the device is plugged in.

    I don't know how deep they are looking for this, but in some cases after uninstalling the program some registries are left(not deleted).

    Hi,
    No, I don't think so, if you ever need to send the laptop for a warranty repair, just uninstall the program you are using for undervolting.

    And how can i be sure nothing is left about this in that case?

    If you laptop ever fails(hopefully it doesn't), the tech support will ask you to factory reset the laptop anyway. Factory reset cleans everything and there is no way for them to know. If the laptop doesn't want to boot up and if you have set a windows password they can't access the drive, unless they reinstall windows. When they reinstall windows all the information will be wiped out, so they can't tell if you undervolted. 

    Anyway we don't even know if adjusting the voltage voids the warranty, as there is no way to fry a CPU these days by just simply increasing the voltage. Undervolting does the opposite-makes the CPU run cooler, so I kind of doubt that it voids the warranty.

    Many thanks, 

    I managed to get a stable CPU around -135. THe device is 5-10 Celsius cooler whilst gaming.

    Should I also try undervolting the Intel Graphich 630 for battery saving sake?

    If I were you, I wouldn't touch it.

    Should I undervolt anything other than the core voltage? Like  cpu cashe?

    Yes, You can undervolt cache as well. From my experience I can tell that sometimes cash won't go as low as core. My 7700hq goes to -138 mV on core and -130 mV on cache. If I try to force -138 mV on cache I sometimes get crashes. I also undervolted igpu to -90 and everything works just fine. But be aware that result may vary form chip to chip though. You will have to find sweet spot for Your hardware yourself. Good luck!

    I use Intel XTU. 
    And I dont know why but I cant undervolt the core and the cashe separately.

    It is best if core and cache are set to the same voltage.

    Should I also undervolt the gtx 1050ti for lower temps?

    Depends on you. I usually don't undervolt the GPU.

    No, unless you have damaged your component some other way. Modifications to processors and other computer parts via undervolting will not void them of their warranty unless doing so has damaged them.
