Hi everyone,
I'm using an HP Omen 16 (RTX 4050 + Intel Core i5-13420H), and I'm facing a strange overheating issue that wasn't there when the laptop was new.
Earlier, while gaming, my CPU temperatures would usually stay between 75–85°C, and I never experienced thermal throttling. However, over the last month, the CPU has started reaching 95–100°C very quickly. It now thermal throttles not only while gaming but even during game installations, software installations, and other heavy workloads. HWiNFO consistently reports thermal throttling on all four P-cores.
To troubleshoot the issue, I've already done the following:
1.Replaced the thermal paste multiple times.
2.Cleaned the entire laptop.
3.Replaced both cooling fans under warranty.
4.Replaced the complete heatsink/thermal module under warranty.
5.Had the heatsink removed, repasted, and reinstalled several times by the HP Authorized Service Center.
Unfortunately, none of these changes made any difference.
I also ruled out the thermal paste itself. I've tried different high-quality thermal compounds, including Thermal Grizzly Kryonaut, thermal paste, and another good-quality paste, but the temperatures remain exactly the same.
One thing that really confused me happened at the service center. Around 10–20 minutes after applying fresh thermal paste, the technician reopened the laptop while checking the fans. He showed me that the paste had already spread out so much that parts of the CPU and NVIDIA GPU dies were visible, almost as if the chips were exposed. The previous thermal paste applications had behaved the same way, even after replacing the entire heatsink.
Despite all of this, I don't have any noticeable performance issues:
1.No FPS drops.
2.No random shutdowns.
3.No BSODs.
4.Games still run smoothly.
The only issue is that the CPU now thermal throttles frequently, which never happened when the laptop was new.
The HP service center is now suggesting that the motherboard should be replaced, but before agreeing to that, I wanted to ask if anyone here has experienced something similar with this model.
A few questions:
1.Has anyone with the HP Omen 16 (RTX 4050 + i5-13420H) experienced the same issue?
2 Does this sound like a motherboard/CPU issue rather than a cooling issue?
3.Would trying Honeywell PTM7950 instead of conventional thermal paste be worth it, or is that unlikely to solve the problem?
4.Since my laptop is still under warranty, should I proceed with a motherboard replacement, or is there something else I should ask HP to check first?
I'm genuinely confused because almost the entire cooling system has already been replaced, yet the temperatures are exactly the same as before.
Any suggestions or experiences would be greatly appreciated.
