New laptop has artifacting/stretching textures while gaming

[AppaTheTechNoob]

I have a new laptop (asus ROG gl552vw-353t) and in the beginning, everything was fine but after a month, some artifacting and stretchinghappens while gaming.
I don't hear the fan spinning as fast as it did before. Can it be that the artifacting is a result of high temps? Can i change the fan speed?
Or is there something wrong with my graphics in my laptop?

If it is that new, contact the manufacturer about it as it should still be under warranty.
