I7-10870h temperature\power problems

[Zekizak]

Please help me with my cpu drop issue.
What is available:
Power supply for max CPU usage 99% temperature stable 44-51°C with lock 2.1Ghz (I use this mode so that the coolers do not fly away)
Power supply for max CPU usage 100%(perf mod) temperature jumping immediately to 60°C and in the form of a cardiogram from 50°C to 86°C , 4.0Ghz - 4.4Ghz at rest
TVB blinking red/yellow.



In games, the temperature goes off scale (thermal paste is new, the system is clean). There is a voltage drop up to 0.88 power to 35W, frequencies up to 2900, CPU load 100%



When you close the game, the temperature instantly drops to normal, increasing the frequency. By lowering the CPU limit to 99%, the temperature returns to 50°C in a few seconds
The temperature can't rise and fall so quickly. I already changed the values in TC(unlock controls, pl=0), but before writing the post, I deleted the ini file and rebooted the PC for the test.
Little log with running game. And AIDA sensors in game.
Can something be done or is it a problem with the PC sensors?

The temperature can't rise and fall so quickly.

CPU core temperatures in laptops rise and fall very quickly. There is a lot of energy and power going through a very small surface area. Laptop heatsinks are not very good at controlling this heat.

is it a problem with the PC sensors?

The core temperature sensors are fine. The problem is your laptop has poor cooling. What thermal paste are you using? Some popular thermal pastes work very poorly on laptop CPUs. Try finding some genuine Honeywell PTM7950 thermal interface material.

It looks like your computer uses an embedded controller (EC) to lower the power limits when your CPU gets hot. The PL1 turbo power limit gets reduced to only 35W. ThrottleStop cannot be used to control this power limit. You can try checking the MMIO Lock box in the TPL window. This will fix the MMIO power limit but I think there is still a separate EC power limit that ThrottleStop cannot control.

You need much better cooling to get maximum performance out of your computer. This might not be possible if the CPU heatsink is too small. This is bad design by the manufacturer. The 10870H is too powerful of a CPU for a laptop with poor cooling. Some different thermal paste might help a little but it might not be enough to fix this problem.

A friend also said that the matter was in the paste, but I changed it relatively recently, which I always use. It's ok, I'll change it to be sure.
Changing the multiplier on the cores had no effect. Also, after a few tips on lowering the frequencies on the GPU, it turned out like this. Made a flat frequency of 1400 consumption gpu dropped to 100 watts. Process power increased to 40 watts with increasing frequency. Turn on dlss plus -40Watt from GPU and plus 5 watt to cpu. FPS is more stable at these frequencies. Apparently it will be necessary to pick the frequency and power settings for each game.

What thermal paste are you using? At high temperatures, some thermal pastes when used on laptop CPUs can quickly pump out and fail.

Finaly, today i found a solution to my problem.

Before, i was having a similar problem wi my laptop : Aorus 15G i7-10870H RTX3070. The CPU was getting HOT instantly when i turn on normal mode or Gaming mode (90°) and than it starts throttling and frequency gets lower when the power% is rising.

The problem like our friend (unclewebb) said : CPU cooler , how ? well, the heatsink was not sitting correctly on the CPU die because of the screws and heatsink it self ( for my situation the heat sink touching the VRM), so what i did is changed the screws to a small factor and than tighten the heatsink carefully just to let sit on the CPU ( with new thermal paste like : Gelid GC-Extreme, good for delided CPUs) .

Now the CPU temperature is good and not reaching 80° in full power, so i pushed the TDP further untill i got 3.5Ghz on full load, thant's enough for me.

I hope this will be a solution for others, peace.
