Utilization and usage are two different things. It is the Utilization data that is spiking. Utilization data is based on the base frequency of a processor. The higher the percentage of turbo boost an Intel CPU uses, the higher the Utilization value will go. The Task Manager also graphs this Utilization nonsense but the Task Manager decided to clip the maximum values to 100% so no one would notice how meaningless these numbers are. The Details tab shows CPU Usage. The graphs do not. If you want to look at CPU usage data, try using HWiNFO.

You can use ThrottleStop to set the power limits of any Intel Core i CPU as long as the BIOS has not locked out this setting. ThrottleStop gives you access to the Clamp options. This can force the CPU to run under its base frequency when necessary so power consumption does not exceed the power limit values you have requested. The BIOS of most motherboards do not give you access to the Clamp options. The 10850K has a 125W TDP rating. Here is an example with both power limits set to 65W. The CPU can still run at full speed when lightly loaded as long as power consumption is under 65W. Enable the C states in the BIOS if you want to minimize light load power consumption. Idle cores that spend 99% of their time in the low power C7 state saves power.

What are you using? Some thermal pastes like the popular MX-4 are only good for about a week when applied direct die to a mobile CPU. Try using Honeywell PTM 7950. You should see much better long term results. It is possible to unlock CPU voltage control. Google search for CFG Lock and your laptop model. Someone, somewhere has done this already. Less voltage can help fix your problem. This website explains the basic procedure. https://brendangreenley.com/undervolting-2020-dell-laptops-like-the-vostro-7500-and-more-tips-to-improve-thermals-battery-life-and-speed/#cpu-undervolt

HWMonitor does not correctly report the maximum MHz. This seems to get discussed about once a week. Try using a different monitoring program.

It is definitely not idle. Open the Task Manager and find out what is running on your computer. Power consumption should be a low single digit when idle.

The 71C Tcase temperature has nothing to do with the throttling temperature. The Core i5-6500 will begin thermal throttling when any if the cores reach 100C. Any throttling before then is not thermal throttling. BD PROCHOT throttling is rarely temperature related.

That is great news! When you swapped in the 11700K, did you check the Task Manager or CPU-Z to make sure all 8 cores and 16 threads were being detected and used? When you install a different CPU, if it has more cores and threads compared to the previous CPU, it is a good idea to check this. If not all cores and threads are being detected, you need to open msconfig, click on the Boot tab, press the Advanced options... button and clear the Number of processors box. This box should always be clear. After you do this, press OK and reboot so Windows can find all of the cores in your new CPU. When you previously mentioned that the 11700K did not make much of a difference, the msconfig setting is often times the reason why. Time to do another CPU swap?

I know you briefly pulled the CMOS battery. Most motherboards either have a switch or there will be two pins on the motherboard that you need to short out to reset the CMOS. Check your manual. You do this with the battery installed.

@Motifator The B660 boards do not support multiplier overclocking. Need a board with a Z series chioset for that.

@RosieDreams Windows 10 does not support 12th Gen or newer CPUs. It treats P and E cores equally. Game tasks that randomly get scheduled on slow E cores can cause stuttering.

@abdelghani I was recently helping a user with a Razer Blade 16 with the newer i9-14900HX and the same RTX4090. He is struggling to run the CPU much over 60W without the CPU thermal throttling. The cooling really is that bad. For comparison, a similar Lenovo Legion with a 13900HX has a cooler that can handle up to 180W. Big difference in maximum performance. If it is not too late, return your Razer and get something else. I think similar Asus laptops are also up in the 150W range. Razer seems to be using a cooler that is designed for the rated Base Power which is only 55W. https://ark.intel.com/content/www/us/en/ark/products/232149/intel-core-i9-13950hx-processor-36m-cache-up-to-5-50-ghz.html You need to disable Intel Turbo Boost to run one of these HX processors at that low of a power level. You need triple that power for maximum performance. Go run Cinebench R23 and see how you compare to the 35000 points that a Lenovo Legion can score. Ask Razer to explain why the cooler they are using is completely inadequate.

If you just replaced the thermal paste then it is probably the thermal paste. What did you use and how did you apply it? At high temperatures some thermal pastes will quickly pump out leaving little coverage of the CPU.

The 12400F does not support any overclocking. None, zero, zilch. Her CPU is using Intel Turbo Boost. That makes the CPU run at its full rated speed. Intel does not want users turning this feature off. Intel encourages users to run Intel CPUs at their rated speeds which includes Turbo Boost. Intel prefers hot and fast over cold and sluggish. 80C is a normal operating temperature for an Intel CPU. Buy a bigger cooler with a quiet fan if you want less noise.

The utilization data that CPUID HWMonitor reports is the amount of turbo boost your CPU is using. The 12400F has a base frequency of 2.50 GHz and a maximum turbo boost frequency of 4.40 GHz. https://ark.intel.com/content/www/us/en/ark/products/134587/intel-core-i5-12400f-processor-18m-cache-up-to-4-40-ghz.html 4.40 GHz / 2.50 GHz = 176% When a 12400F is running at 4.00 GHz you get utilization of, 4.00 GHz / 2.50 GHz = 160% which is more or less the same as the 159% that HWMonitor is reporting for your CPU. As more cores become active, the amount of turbo boost automatically decreases. This is how Intel designed the 12400F to work. If your other computer is only showing 100% utilization in HWMonitor then your computer has a problem. That computer must have Intel turbo boost disabled. 2.50 GHz / 2.50 GHz = 100% I do not understand why anyone would want to run their CPU at a fraction of its rated speed. Your computer is not set correctly and now you are trying to screw up your girlfriend's computer too. No more fixing things. Leave her computer alone. It is working as Intel designed it to work. Turbo boost has been a feature of almost all Intel CPUs for the last 15 years. It would be foolish to disable this feature. Here is my CPU running at 5.00 GHz. The default base frequency is 3.60 GHz. 5.00 GHz / 3.60 GHz = 138% Utilization numbers higher than 100% are completely normal for any Intel CPU that supports turbo boost. Do not compare HWMonitor Utilization data to the Task Manager Utilization value. The Task Manager rounds down and caps any Utilization value greater than 100% and reports 100% max instead of the value that HWMonitor reports.

I would not assume that. Intel sets the default thermal throttling temperature to 100C for a reason. Intel has specifically said that they cannot guarantee long term stability if you choose to operate your CPU beyond 100C. Set this back to the default value.
