Fan at max speed, vertical lines, burning smell

Temperatures and fan speeds start out what I believe is normal and start ratcheting up over time, I'll try this tool and see if I can see what's going first. I wondering if dust build up could cause this heat build up?

@bclingan Yes! Dust, old thermal compound, any number of things could cause this. What you just described was exactly what I suspected. Check GPU temps too and report back. Good luck again!

EDIT: Also, be very, very careful. That burning smell is bad, keep the device off whenever possible until you fix it. Prolonged extreme heat is very damaging to components.

I blew a ton of dust out! Sadly I didn't note all the temps before I started, but I believe they are lower than what I recall. Does anyone know if these are in the correct range?

Ambient = 16

CPU Diode = 31

CPU Heatsink = 28

CPU Proximity = 34

GPU Diode = 90

GPU Heatsink = 84

GPU Proximity = 79

HDD Proximity = 29

LCD Proximity = 27

MCP Proximity = 49

MLB Proximity = 34

Northbridge Diode = 60

Northbridge Heatsink = 56

Optical Drive = 28

Power Supply Proximity = 35

Fan climbs and maxes out still after being powered on for several minutes.. wondering what to check next.. heatsink? thermal paste?

@bclingan From what you described, I'm willing to say all of those temps are fairly normal, except for the GPU. My R9 380x is known for being hot, it never passes 80C. I'd replace the thermal paste on the GPU, also the CPU while you were at it. There is bound to be a lot more dust hiding as well. I appreciate your response. Hope that helps!
