Undervolting 6600k

[Tc99]

So ive got my first PC, its a used 6600k, h170, h100i cooler. since i cant overclock the cpu with my current mobo and i saw a few articles about undervolting to reduce thermals, thats what im thinking of doing. its hot af where i live, idle temps are around 40C, even typing this while downloading a file pushes it to 50C. the system is stable while gaming, although even 1 cinebench run will push temps to ~80C. since im pretty new to this, i'd like some advice or guides to get there. thx in advance

I recommend downloading intel XTU utility, starting at -50mv, run cinebench r15 at realtime process priority (can be found in details in task manager), then go down -10mv repeat until your system freezes then go up 10mv. Then put that stable undervolt into bios and run 10 cinebench r20 and 10 cinebench r15 realtime process priority runs, then run intels xtu stress test for 10mins. After doing this you should have a stable undervolt, if you ever crash raise voltage by 10mv.
