If Undervolts Don't Decrease Temperatures, Does This Mean Repaste?

[tobithelegend]

I have an HP Omen 15 laptop with 8750h and RTX 2070 Max Q. The CPU naturally used to reach 96 degrees or more (PROCHOT at 97 degrees). Never ran any more graphics demanding games earlier (laptop is now 5 months old only) so never had problems. But now when the processor reach 3.9MHZ it overheats and its frequency starts decreasing without the temperature decrease. Since GPU shares the heatpipes, the GPU clocks also decrease however GPU temperature never went about 86 degrees.

 

Tried undervolting. My laptop is stable at -144 mV. Did this for both core and cpu clock using throttlestop. Ran the benchmarks but no affects on CPU temperatures. Even at 3.4GHZ speeds it throttles at max temperatures that is 97-100 degrees. The voltages in throttle stop do show that the undervolt is under affect. Have tried many different things but nothing seems to work. If I am gaming by using the base clock of the processor (2.2), the temperature even then reaches 90 degrees. Can anyone help me out on this matter? My ultimate conclusion is that it needs a repaste. Is there anything else I can try? 

As you can see in the image below. Even at default clock and such low power draw, it is reaching 94 degrees and GPU is locked at 86 degrees with fixed clock. The clock doesn't go above at this tempearture but if I use GPU Z, the clocks can reach upto 1800MHZ and more.

thanks in advance

GPU might be hogging the cooler then since GPUs are very dynamic and will squeeze extra performance out of every degree. You might want to impose a power limit on the GPU and see if that helps.

At that frequency, it shouldn't HOG power, NO? But if it is hogging power? What's the solution? Also, at that frequency the GPU is at 700mV while If i run GPUZ benchmark, it doesn't got down below 850mVs.

Some good looking gaming oriented laptops have second rate cooling.  Follow your instinct.

The heatsink and fan are barely adequate.  They might have been OK the first day you got your laptop but cooling is not OK now.  Re-paste and try to think of anything that you can that will improve cooling and reduce temperatures.

Both are too hot

 

Consider repaste. Note that undervolt doesn't always cause a decrease in temperature.

I am not sure. In Laptops, do both GPU and CPU need repasting or just the CPU? What sort of paste would be best?

Undervolt wouldn't reduce temp when the CPU is throttling that much, it'll run just as hot, only a bit faster. Same with repaste, both GPU and CPU will still throttle, just hopefully a bit less.

It's a laptop, it's how it is, very few actually have the cooling needed to maintain full performance of both components.

Hmm. Will send it warranty once i guess, if it doesn't reduce the issue, i guess will replace.
