This issue has just cropped up today. While I was watching YouTube (nothing else running) the fan above the CPU just took off, sounded like a mini jet starting up.
Now I am pretty sure that the CPU heatsink is the cause of this but I don't understand why it would be. I got this computer less than a year ago. Another curious thing is that there are 2 fabric cables going from the Omen heatsink to the fan that is doing over time. 1 of those cables is significantly hotter than the other.
I also installed CPUID and when I start to watch YouTube the temps go from 65 - 70 to 95 - 100.
Not sure what's going on but I can barely watch YouTube atm without it going into over drive, any help is greatly appreciated.
