An 11th Gen cpu should NOT be thermal throttling, which laptop model do you have with this i7-11800H cpu? As at idle, the cpu should not be in the high 78°C, have a look HERE and follow these guides, if none of those work then you should have the laptop analysed by a technician so he can pinpoint the exact problem. Good luck.

The Intel Core i7-11800H experiencing thermal throttling, even when idle, is not normal and indicates a cooling issue. This could be due to a variety of factors, including inadequate cooling in the laptop, insufficient thermal paste application, dust accumulation, or even problematic fan curves. Addressing this requires investigating the cause and potentially taking steps like cleaning the laptop, reapplying thermal paste, adjusting fan curves, or even undervolting the CPU.

Here's a more detailed breakdown:
1. Identifying the Problem:
High Idle Temperatures:
An i7-11800H should not idle at high temperatures like 70°C. Ideally, it should be much lower, closer to ambient room temperature.
Thermal Throttling:
Observe if the CPU is being throttled (reducing clock speeds to cool down) even when not under heavy load. This can be checked through monitoring tools like ThrottleStop or Intel Extreme Tuning Utility.
Limit Reasons:
If throttling is occurring, note the reason provided by the monitoring software. If it's "THERMAL," it confirms thermal throttling.

2. Potential Causes:
Poor Cooling:
Laptops can have inadequate cooling solutions for the i7-11800H, especially under sustained loads. This is a common issue in thin and light laptops.
Dust Accumulation:
Dust buildup on fans and heatsinks can restrict airflow, leading to overheating.
Thermal Paste Issues:
The thermal paste, which transfers heat from the CPU to the heatsink, can degrade over time or may not have been properly applied during manufacturing.
Incorrect Fan Curves:
The laptop's fan control software might not be adequately adjusting fan speeds to match the CPU temperature.
Power Limits: Incorrectly set power limits in the BIOS or through software like ThrottleStop can also contribute to throttling.
