so i have posted a thread in used to day about this problem, but im still kinda not sure about the fan itself were a defect product. so here is the main problem, my fan is so loud, the loud is not wind loud sound, but the thing that loud is some kind of *rrrrrrrrrr* sound, seems like the motor loud or something but im not sure, is this thing a common thing or this is some kind of trouble with the fan? should i replace or just let it be like that, for sure thermal is still relatively normal, but last couple of times the gpu and cpu temperature were kinda high, i overclock the gpu, but the average temperature also kinda raising up, for sure the cpu is kinda worying, it is averaging at around 80 C and can goes up to 89 C sometimes even though the cpu itself were already undervolted
