Acer Predator Orion 3000 Model no: PO3-630 is overheating

Hi,

I bought my Acer Predator Orion 3000 computer back in the start of 2021. I had it connected to a monitor with low resolution, and I did not notice many issues.

On my birthday a couple of days ago, I got a 1440p computer screen and I was so excited to use it. However, upon playing for just 5 minutes of Overwatch, Dead by Daylight, Minecraft with shaders, etc. my screen goes black and unresponsive indefinitely.

I followed this guide to replace my cooler with the same one in this link:

However, even after switching the cooler a couple of hours ago, I am still faced with the same problem. I have de-dusted it and everything. Please let me know if any of you know a solution. Thanks.

First of all, which PO3 model do you have? Your full model number is usually on the same sticker as your serial number, it should look something like PO3-xxx-xxxx. Is there a chance the issue is with the monitor and not the computer? What temperatures are you seeing?

The PO3 model is: Predator PO3-630 (PO3-630_H_WLP)

The temperatures quickly go beyond 85C, and the screen turns off and the PC freezes when temperatures hit 90C.

I did replace the cooler with Noctua NH-U9S CPU cooler. I removed the old thermal paste and applied new, but it still quickly hits those degrees even so. Those temps are seen with any high-end game like Overwatch on Ultra, Minecraft with shader,s etc. This happens just minutes after launching those applications.

As for the display, it is brand new and I don't see how the display is having issues, as the issues stem from the CPU temperature.

I am thinking about undervolting the CPU, but I hope there is any other solutions before messing with things I don't know. Thanks

It sounds as if the thermal paste wasn't applied correctly, either too much or uneven can cause those symptoms. The Noctua is a good choice for a cooler. Thermal throttling, which happens around 93C IIRC doesn't cause a display to go off, and a thermal shutdown, which happens when exceeding 100C, will turn the computer completely off, not just the display. I wonder if your issues are actually with the GPU card overheating?

Few things come to my mind. Sorry if these sound silly, and you have already checked everything, as I am sure you have.

Remove the cooler and see if the connection between IHS and cooler is good.
If not, double check that you are using the correct plastic "washers" and screws.
Are all fans spinning (should not even boot if CPU fan wasn't).
What is the temp on GPU? Check fans.

Perhaps, though I have applied the thermal paste and wiped it off and reapplied three times now. Here is how it looks:

Upon removing the cooler, it does look like the thermal paste is evenly spread out. I have also applied less than what is above, though that is the max I can apply before it spills out. Could be related to GPU temp, but I am not sure how to check.

The cooler is fine, the fan is spinning. Not sure what the temp on the GPU is

The cooler you have now should be more than enough to keep even an 11th gen i7 from crashing because of temperature. Well, unless a heatpipe has a crack and the heat doesn't get trasferred to the fins properly.

Does the PC still crash if you run it without side panel?

The problem started with the new monitor. Your GPU (RTX 3070?) isn't only doing most of the work, but it's also working a lot harder than it used to. Try to check your GPU's temps. MSI Afterburner is one of the many programs that can tell you loads of info about what is going on while gaming.

Yes, it sounds more and more like it's an issue with the GPU, not the CPU. There are utilities for monitoring GPU temperature, and I believe even the standard software from Nvidia will do that.
