hp omen 45L overheating with 90D error sometimes

[r92037]

I have an HP OMEN 45L PC (Win11 Pro)  that sometimes when I am not using shuts down. Typically this is not when I am using it. When powered up it displays the 90D overheating error. I have called tech support and they updated the BIOS but this did not help. I have installed a temperature monitor to log a large array of processor properties and I can see that sometimes the P-cores or E0cores will dramatically rise from around 35C to over 90C for a few minutes. This will cause core thermal throttling to occur.  but the temperature at one or more cores will reach 100C.  During this time the computer did NOT shutdown, but I am concerned about this behavior.

I have updated the BIOS, checked for blocked vents (none), and cleaned the air filters.
Here are the power settings:
"balanced power settings"
Hard disk off 60 minutes
Sleep after 240 minutes
wake timers enabled
PCI express set at Moderate power savings
Min processor setting 5%
Max processor setting 100%
Display off after 30 min
"Bios-System Firmware" shows "Up to Date" On the HP PC Hardware DSiagnostics window 2.7.2.0

I would like to change the settings of the PC so that throttling occurs at a lower temperature to insure the lifetime of the PC.

I am willing to sacrifice performance.

Any help is appreciated.

I started having the same issue roughly 2 weeks ago.  45L Omen Gaming PC.  One change - I had to update the CPU to a 14900k because of the microcode damage.

Thanks, how did you update the CPU?

[Davion77]

I started having a ton of crashes on games.  Reading, the 13900k chip that comes native in the PC is subject to damage due to a faulty voltage setting in the microcode.  So I swapped it out with a 14900k and updated the microcode.  Everything was fine until roughly two weeks ago when I started leaving the PC idle only to find it off.  Next boot I would get the 90D error.  I hope you can get a reply from HP on this.  I am eagerly awaiting.  In the meantime, I plan on changing the thermal paste this weekend.

Opinions or troubleshooting suggestions in this response are provided independently. I am not employed by: HP, Inc. or the HP Forum.

Try the latest BIOS update for your MB, which fixes Intel CPU stability issues, available at this HP Site. Skip this option if your PC is running HP BIOS version F.31 Rev .A.

Doing the BIOS update is your decision. Be patient when doing a BIOS update, don't interrupt this update and loss of power during a BIOS update can corrupt the BIOS.

This second Site has some troubleshooting tips you can try to check the Intel CPU.

You should, at least, run the Intel processor diagnostic tool available for download at this site.

As @Davion77 suggested, you could also try redoing the CPU TIM to see if this drops temps.

You really should contact HP Support if your PC is in warranty and the Intel diagnostics test fails. You should contact HP Support first (warranty service) concerning CPU temps in any event.

Hi Bill

Thanks for the support suggestions.  A few days ago I opened a case (# :5142527382) with HP as this PC is still under warrantee.  They had me update the bios.  Interestingly, MSINFO32 shows 

BIOS Version/Date        AMI F.31, 10/23/2024 (the BIOS startup screen also shows F.31)

Which is almost what you suggested I update to (the link to the bios shows a date of 10/25/25).   So, please confirm that I should again update the bios as the HP PC Hardware Diagnostics Windows 2.7.2.0 shows "BIOS-System Firmware Update" windows shows- UP to Date"

Note that that support case was closed as the evening after the bios upgrade, the PC did not shutdown, so case closed. And as you might anticipate, the following night it shutdown again.  Now it does not seems to shut down as frequently, but it still does.  Also, interesting it does not appear to have shutdown during the first 5 months of having the PC if I read the bios entries correctly (I do not recall any changes to loaded software when the problem started to occur).

I develop data acquisition software so it is important that the computer run for days uninterrupted (no such software was running recently when shutdowns occurred). 

While running the intel processor diagnostic tool, all passed, and I also noted that core thermal throttling did occur at 100C during one of the tests. 

I do not want to disassemble the CPU and redo TIM, particularly since this PC is under warrantee.

My pleasure.

BIOS version F.31 is the latest. There is nothing you can do with the BIOS at this time.

I think you have a faulty CPU cooler or the CPU cooler TIM needs replacing.

HP would never configure BIOS settings to overclock the CPU at the factory. And you should not encounter any CPU overclocking options within the PC's BIOS.

The CPU will burn out if you don't solve the thermal problem.

Have you checked: CPU and MB voltages using HWiNFO portable? The MB could have a voltage problem that you could not fix since the BIOS has no overclocking options.

You would have to present your findings to HP Support to have the PC repaired in warranty.

Thanks Bill:

I just got off a 1 hour support session on support chat.  The only things suggested was:

1. clean the fans/filters

2. update the bios, but they could not say if their bios F.31 was different from F.31a so and they would not respond to my question if they were different

3. "We need to bring it back to factory configuration so that we can troubleshoot on your computer." which means revert from win11 pro to win11, remove the added hard disk, and presumably reload the OS.  

No questions about any settings, logs, no interest at all.  It is back to the days of "reinstall the os" solution to any problem.  it is quite disappointing.

What I would really like to do is to move down the temperature that cpu throttling starts to see if this solves the problem in case that there is overshoot in the temperature sensor causing shutdown and throttling does not have a chance to stop the temperature rise.  The shutdowns, from the hwinfo logs I have seen, occur in the early mornings before I log into the PC, where I see periods of high cpu activity, combined with temperatures reaching 100 and accompanied by throttling.  My guess it that this might be virus scans, or disk backups happening.  I have sleep enabled and gaps in the log suggest that it is waking up and doing some significant activity, then resuming sleep. I will continue monitoring but if you can point me at any way to lower the temperature where throttling occurs, I will give it a try.

I guess these are machines are not built as solid as the HP9845 workstation I once used.

Sorry to see HP Support will not give you an RMA to fix the system.

BIOS version F.31 and F.31.A should be equivalent. Try F.31.A to see if the update will flash your PC's BIOS.

Doing a factory OS installation back to W11 Home using HP Cloud Recovery or doing a full OS reset and then removing drives you have installed serves no purpose, in my opinion.

But HP will not troubleshoot a modified system so you would have to cooperate to get warranty service.

HP, generally, replaces components during warranty service.

My only advice would be to redo the CPU TIM. Then replace the HP CPU cooling system. You would then have a possible MB voltage problem if the above steps don't fix the problem.

It's either do it yourself or get HP to honor the warranty (preferred).
