Hi there,
@unruledboy
Indeed, sounds like some fuzz or hair is stuck in the fan.
Get a cold blower (like the exhaust of a vacuum cleaner with a clean bag and filter, or “canned air”) and blow into all ports and vents. You just might clear it up, or relieve some noise.
@
sharpuser yes, it is working, and I forgot to come back to thank your help! SORRY!
One thing though, now I got a 4K 43'' inch external monitor, I would close the lit and only use the external one, I can feel the CPU heating crazy, so I have to use a dedicated big fan to blow the wind to it so it could cool down.
NOT good, but works, if I open the lit, I can feel the heat on the screen as well, but after sometime, it is fine again, even without the big fan blowing at it. I mean: with lit closed, HOT, with lit open, warm enough.
So is it by design or it is a bug?
