ASUS M508VD Undervolting to Lower Temps

Hi Guys,

I recently bought an VivoBook M580VD for professional work and light gaming. I've always built desktops and this is my first "gaming" laptop in a long time.

I ran CS:GO over the weekend and decided to look at the temps out of curiosity and noticed the i7 7700HQ was cooking at a peak of 96 C and hovering around 92 C. Coming from desktops that seems like practically melting to me. The GTX 1050 was at a consistent 79C which seemed a bit more reasonable.

I contacted ASUS and to see what they had to say and they told me to RMA the machine. I've heard nothing but awful things about their customer service, particularly their RMA process so I would really like to avoid doing that over high temps and only resort to an RMA if something actually dies for real.

I undervolted the CPU and was able to hit -.155 before it crashed and dialed back to -.145 to get stable. That dropped my temps down to 91 C peak and hovering around 88C. What interesting is if I only stress test the CPU and not the GPU/CPU combined, I barely break 75 C on the CPU. The GPU seems to run at a consistent 75-80C. I assume this is because they share a heatsink.

So this brings me to my real question. I can obviously repaste at the risk of voiding my warranty and likely get right in the comfort zone. I was also thinking about undervolting the GPU to see if I can squeeze those temps down a bit to see if that drastically affects the CPU temps under load.

Has anyone had any experience repasting and then sending their machine in RMA down the road for something else? Or has anyone undervolted their GPU and seen decent temperature drops?

Thanks!
