Hello guys, I have really old notebook from 2013 18 R1 with dual GPU and frankly I'm impressed it lasts so long, but recently on system start at some random point fans stop then start blowing one at a time for like 2 seconds then only CPU fan keep working at max speed(pretty much same sequence as at system testing) while both GPU fans just stop and refuse to work. When this happen whole system freezes for few seconds then resumes normal work but GPU start overheating. I found that I can reset fans to normal with help of HWiNFO, but it helps for exactly 15 minutes then exactly same happens. Beside this everything works perfect, I even tried FurMark for 5 mins and system was fine and stable no overheating until this fan issue happens. Bios testing utility show no errors with both GPUs and fans. Still I'm pretty sure it must be some kind of video adapter failure but before unscrewing laptop I wanted to ask if anyone has any insights into this, thanks in advance.
