Question İ5 12450h cpu tdp limit is dangerous or not?

[Kerek46]

Hello friends, I have a laptop with an i5 12450h processor, and its temperature started reaching 95-100 degrees under load. I could clean the fans and replace the thermal paste to lower it, but I don't want to void the warranty.

Instead, I found a program called QuickCPU and reduced the turbo long power max to 25W, and turbo short power max to 35W. I also set the maximum allowed performance to 80%.

Default setting is turbo long power = 45w, short power 120w.

Currently, the processor runs at 3.6 GHz and the temperature is 80 degrees during gaming. Only the FPS dropped a bit.

My question is, will these settings damage the processor?

 

[SteinFG]

No, lowering TDP won't damage the processor

 

[Kerek46]

No, lowering TDP won't damage the processor

Thank you, I significantly reduced the default values. I reduced the 120w to 35w and the 45w to 25w.

I was wondering if the processor would get damaged if it is forced to operate with less power than it should receive.

 

[SteinFG]

Yeah nothing negative will happen except low clockspeed

 

[SteinFG]

Though I'd reccomend just cleaning the fan and changing the thermal paste, after warranty expiration

 

[Kerek46]

Thanks sir,

Finally, if I set the 'Maximum Allowed Performance' section to 100% again in the Speed Shift section on Quick CPU program and keep the power limit in the 'Turbo Limits' section as mentioned in my previous messages (25W - 35W), will it cause any issues?"

I didn't use this specific program, so can't say how different settings impact each other, but I don't think the chip can even hit 80 or 100% of its max performance with such power limits in place, so the setting won't have any effect

Thank you very, very much, sir. I will use my laptop with these settings. Have a good day.

Hello again, sir. This is the situation after the latest settings. Normally, it goes up to 4.4 GHz with turbo boost, but right now I've only set the turbo long power max to 25W and the turbo short power max to 34W in the quickcpu program. I haven't changed any other settings.

This performance is sufficient for me at the moment. There won't be any issues, right?

Default setting is turbo long power = 45w, short power 120w.

Have you tried putting long and short to 45W and leaving performance at 100% ? It should have good enough cooling for 45W all the time if that was the default setting.
There are no issues from setting power too low, until you go so low that the CPU can't even start anymore, but if your cooling is good enough you are losing performance for no reason.

When i set for 45w. Temp is more than 90+.

You could undervolt CPU using QuickCPU or more popular ThrottleStop: https://www.techpowerup.com/download/techpowerup-throttlestop/

Btw, since when cleaning fans void warranty?

Intel has locked the ability to undervolt so I can't undervolt the i5-12450H processor. I need to remove the back cover to clean the fans and removing the back cover voids the warranty. When looking through the back cover, I can see that the fan blades are about 60% covered in dust. For now, I've found a temporary solution by reducing the wattage to manage the temperature.

Use a vacuum cleaner, bring in close proximity to both laptop's air intake and outake, use your hand to make a seal between vacuum's intake and the laptop surface (also prevents any scratches and marks).

It works wonders at removing dust buildup and does not fill the room with dust like using cans of compressed air.

I didn't know about that (Intel Undervolt Protection), looks like it's just another reason to avoid Intel.

Thank you, I will try this method, but I'm afraid the fans might become loose and noisy due to the vacuum effect.

Yes, unfortunately, Intel locked undervolting on some processors after the 12th generation. The i5-12450H is one of them.
