need help with power limiting my i7-8750h

[cold3r43]

i have an asus tuf gaming fx505 laptop that i borrowed, and after trying to play some games, i realize that the cpu is thermal throttling under any load, running the simplest of games. im looking for a way to reduce the power usage to a point where it wont affect the performance too badly (not power limit throttling), im completely new to using throttlestop, any help is appreciated.

You borrowed this machine? Is the owner okay with you dinking with the settings?

You are trying to put a bucket under a leak when the correct solution is to fix the leak.

Unless you are sitting out in the hot sun, it should not be throttling "under any load". Heavy loads, yes. Idle to medium loads, no.

I would first look to make sure (as much as possible without totally disassembling the laptop) it is clean of heat trapping dust and that the fan(s) are spinning properly. Then maybe consider a good self-powered (has its own power supply) cooling pad.

And if it is quite dusty its probably already dried out any thermal paste that was previously applied at that point leading to these temp issues.

he is ok with me adjusting the settings, as he rarely uses it anyway

regarding the fix the leak, i have just gotten it repasted yesterday at my local comp shop, and i am playing with a cooler pad + my fans on overboost, and it is still thermal throttling.
i have checked to see if the fans are even working, and according to my bios its spinning at around 4.6k rpm on gpu and cpu, but my cpu hits thermal throttling temp way before the gpu even goes above 70-75 on gaming. On idle, the temps are around 60c on both the cpu and gpus.

And if it is quite dusty its probably already dried out any thermal paste that was previously applied at that point leading to these temp issues.

forgot to add i just had it repasted and still no noticeable impact, i think it only took off like 1-2c

the laptop is pretty old, like around 2-3 years, so i dont expect too much, but any help is appreciated

for reference, im getting around 100-110 fps on valorant with all low settings, and it is still pretty sluggish ( i assume because of the cpu thermal throttling)
thanks in advance

Sorry, but that is not a thing.

It does not matter if it dries out. Contrary to what many seem to believe, TIM never needs to be replaced just because it is X number of years old, or because it has dried out. It will easily last 10, 15 years or longer AS LONG AS the cured bond between the two mating surfaces has not been broken.

I note there is not one TIM maker, CPU/GPU maker or cooler maker who says TIM needs to be replaced regularly.

The ONLY reason TIM comes in a semi-liquid form is so you can squeeze it out of the tube and spread it out easily and evenly. Remember, the purpose of TIM is for the solid particles to fill the microscopic pits and valleys in the mating surfaces to push out and prevent any insulating air from getting trapped between the device and its heatsink. Even if those liquid solvent components dry up, the solid materials remain in the microscopic pits and valleys and are still doing their job.

Yes, a fresh new layer of TIM "might" provide a few degrees cooler temps, but the fact remains, if your systems actually "needs" those few degrees to keep from crossing thermal protection thresholds, your temps are already too high and you have bigger, more urgent cooling issues to deal with first - such as case cooling.

Which fits the typical (2 - 5°C) improvement normally seen. Sadly, the risk of damaging a pin, the socket, or worse, zapping the CPU with ESD is greater than a few degrees of extra heat an old application of TIM might impose.

I don't see any temps in your last post to indicate why it is throttling. Perhaps there is a setting in your BIOS Setup Menu that is just set too low? I note according to the ARK for your CPU, your temps your well under the 100°C T-Junction rating. That said, the CPU is not the only heat sensitive device in there.

You cannot rule out that some component is failing.

i have changed some stuff already in the throttlestop setting, as i wanted to see if it would have any noticeable reduction in my temps, so not all of the settings are default.



in regards to throttling, i have confirmed that the cpu is indeed thermal throttling, via means of some stress testing and running a game performance, i'll send a csv file for my hwinfo64 log
the f.csv contains the log while having furmark and prime95 on, and the val.csv has the logs for when i run valorant for 10 minutes on all low settings.


prior to installing throttlestop, i had 95-96 on running any game, and roughly 65-70 on idle.
look forward to your reply

and roughly 65-70 on idle.

For idle temps, that is way too high.

There is no set rule of thumb for what idle temps should be. This is for several reasons. Every computer is different. Ambient (room) temps are different. Background apps are different.

When the user is idle, that is often when Windows and our security programs start doing housekeeping, updating and scanning tasks.

But when the system really is idle, the CPU temp should NOT be a whole lot more than ambient (room) temps. 65°C is 149°F and I am sure that is WHOLE LOT MORE than your room temperature.

So something is wrong from the start and I suspect case cooling - assuming your CPU cooler is properly mounted and working.

I recommend you reset everything back to the defaults. Ensure nothing starts with Windows except the necessities - typically just your security apps. Then see what your idle temps are.

Also, please complete the TPU System Specs so we can see what we are dealing with.

its a laptop, so im not sure how to fill the tpu system specs, how do i fill it?

Sorry. I forgot. My bad. I'm a PC person and too often get tunnel vision.

i've updated the tpu system specs as best as i could, now what

edit: does throttlestop settings n eed to be applied on every reboot?

 

[Bill_Bright]

Sorry, but Throttlestop is out of my wheelhouse but I am sure you don't need to reset them with every reboot. Hopefully someone with more experience with it will stop by with some advice beyond what I gave above.
