AN515-53-55G9 thermal shutdown/system crash events

User72116702

So, I’ve had my Nitro 5 for nearly 2 years, kept up with it (software updates, cleaning internals, etc.)  And I’ve been having thermal shutdown/system crash events fairly often with it for about a year.  I just found this forum today so that’s why I’m only posting about it now. 

These events come in one of three forms.  The first, and most common one, is a complete system freeze paired with a black screen and the fans screaming.  The second, still fairly common, is the system will freeze on the screen it’s on and only resolved after forced restart (holding power button until shutdown).  These two can only be resolved by a forced restart or shutdown with the method I just described. 

The third one, which has only occurred maybe once (which leads me to believe it’s unrelated) is that it’ll force restart itself.  Thankfully, never had a BSOD, yet. 

So, when these events started happening, I started monitoring.  I noticed that when these events occur, the system is under heavy load and the system is running INCREDIBLY hot when these events occur, with CPU temps between 95 and 99C (and even 101C once].  I know it’s a laptop, but I don’t think those temps should ever be considered normal.  I even removed the cooling system (my laptop is out of warranty anyway so I figured why not) and applied new thermal paste to the GPU and CPU then did a deep cleaning afterwards of the cooling fans, etc.

Im just at a loss, and it’s happening so frequently now that it’s almost impossible to use the computer for much more than my college studies.  I bought it because I wanted to be able to game on it, and take it with me for school or when I travel. I’m starting to grow frustrated and I’m reaching out here for help.

Summary of hardware changes:

Removed OEM ram and installed 16 GB PNY 2400MhZ DDR4 Ram

Added 1TB seagate HDD from previous laptop with all my stuff on it. (Spins at 5400 RPM)

Removed cooling system, cleaned processor and GPU with isopropyl alcohol to apply new thermal paste. I used Arctic MX-1. No other changes 

Anything would be much appreciated

Also, I think the model number says it but Im running the following:
Imtel i5-8300H
Nvidia GeForce GTX 1050Ti, Discrete.

Thank you, again.

Most likely a bad paste-job.

Repaste the laptop with quality thermal paste or give it to professionals to do it for you.

As you can see, the thermals are the culprit. Check that you have repasted everything that was pasted in factory settings.

I remember on my Asus ROG Strix GL702ZC: That unit needed 4 repastes until it no longer:

a) Thermal shutdown as soon as any 3D program is launched
b) GPU clock going from 1077 to 300 back to 1077 ad infinitum in intervals of half a second or so in any 3d program (after first thermal shutdown repaste)

Most laptops are quite sensitive to repasting so if you repasted or the paste has dried out or anything in between, you will get bad thermals

Another bad thermals culprit could be the fans. Check that both are running during any load. I've seen laptops work with the GPU fan dead (and a lot of heatsink designs lead to CPU heating due to GPU heating)
