HP Omen random "overheat" shutdowns

[Daveorock]

I bought this (customized) HP Omen 15t laptop about 7 months ago, and as of earlier this week started experiencing random shutdowns. After booting the computer back up it shows a screen indicating it shut down because it "overheated". The issue is it wasn't actually overheating.

I can be doing anything/nothing and it still happens. I have not changed anything recently. I have speedfan installed, and looking at the graph of temperatures, whenever this happens the temp1 sensor (it's the odd one out between the hard drives, gpu, and cpu sensors) jumps from the normal range (30C to 65C) to anywhere from 140C to 200C in an instant, before returning to normal in the next instant. Since there is no good reason that a componenet should be able to do that (and survive), I figure it's either a software issue or faulty sensor, but I don't know. It will also do the same thing but read the temperature as 0C, but it doesn't shut down when that happens. I have screenshots of the temperature chart, I can post them if requested.

Has anyone seen this happen before, and know what needs to be done to fix it? Thanks.

Thanks for the input, but the laptop is not actually overheating. I'll try to post a picture here of the temperature graph (the last time I tried to post an image it didn't work). Within a tenth of a second, the computer things that one (and only one) sensor has jumped from 30C to 200C, almost hot enough to melt tin... obviously that can't be happening. It's not the CPU or GPU, either. Those are the normal lines you can see in the image.

Hey @Daveorock  
  
Did you get your problem fixed? My Omen laptop is also acting up like that but I haven't recorded a graph like yours yet.

[Daveorock]

I sent it in for repairs (attached with a very precise description, and screenshot of the graph), but they still thought it was overheating and just replaced the fan, despite my insistence that it wasn't actually overheating. I'm 99% certain it's due to a faulty temperature sensor on the motherboard. I haven't had many issues as of late, and my warranty just expired, but if it had continued like before I would have insisted on that sensor being fixed or on getting a replacement motherboard. It seems to be a joint hardware/software problem too (ie, sometimes the temp goes to 0 for a second and it does nothing, some times to 140-200C for a second and shuts down), and updating the BIOS has seemed to help *a little*. Not totally fixed, but much more livable.

Hello, i bought a hp omen 17w213nf 4 days ago and it just did the same thing while I was playing, but when I turned it back on the pixels were weird not showing something clear. I completely shut it down and when it turned it back on it updated windows and that's when I remembered I had programmed the update at the exact moment. Is it a coincidence or is the computer mistaking overheating and updates?

[Daveorock]

I highly doubt it. I'm very conscious about when I have updates. The computer always gives me a "thermal shutdown" message upon restart, so it's not just updating--it's actually shutting down because it thinks a temperature sensor is reading some ridiculous value. It is usually infrequent, only happening now when I have the computer on for some time (like 5-8 hours), but can happen multiple times a day. Given that updates aren't pushed multiple times a day, I don't think that's what's going on.
