High temperatures acer F5 573G 59AJ

While browsing temps are normal (50ºC~60ºC), but while gamming (cs go for ex) I usually get 85C~90ºC in CPU and 75ºC~80ºC in GPU.

I've tried using a program called notebook fan control with e5-471g config. While using this program temps where much more controlatted. Max 73ºC~75ºC CPU and 65ºC GPU. But I also found something unpleasant, ahci latency increases a lot and I got random stutter in games (1-3sec of duration).

So what I ask is, why don't acer enginners or IT develop a program to control F5 573g fan speed or at least enable a way to change it values in BIOS?

Best regards,
