Hello guys. Basicly i was playing league on my hp g5 250 laptop that i bought new 18 months ago when it shut down. Prior to that i had no overheating issues as my fps didnt drop in game. When i turned it back on it gave me 9b fan error meaning that internal cooler in it died. I went and replaced it with second hand cooler that worked for few hours in it before it died as well, this time i inspected the cooler and controller chip on it fried. Now i am well aware that eather i had bad fortune with this second hand cooler (it was really dusty when i bought it) or there is something wrong with laptops mother board. Does any of you guys have an idea what could be causing this problem?
