Improve cooling on I7-8650U (epicly solved)

[TheTigerJunior]

I'm making this short. The temperatures on this cpu is kinda high since I have a laptop with bad cooling. The temps didn't drop after replacing the thermal paste with silver mx-4 but adding more heat to this cpu. Any tips?

Here's the max temperatures in case you'll need it :

Hi!
I would say that these temps are ok for a laptop computer in normal to high usage. Can you measure the Room temperature? And also, the laptop is in a safe place? Like on a desk and not on a bed, please xD.
Please, also specify the Laptop model, so we can have some better guess. And are you on idle and it's hitting this temps or are you trying to game/render, some heavier task?

 

[Vya Domus]

Trust me when I say you're temperatures look great compared to other laptops.

MX-4 isn't silver. Arctic (former Arctic Cooling) doesn't have anything to do with Arctic Silver AFAIK.

The room is temperature is most likely 27C - 32C. The model is Dell Latitude 7490.

Thanks but I think I need to lower the temperatures more for long-term gaming

Sorry I'm new to these stuffs.

No problem. Is the heatsink and fan clean of dust etc?

Kinda clean. I bought this laptop before the quarantine this year.

Alright, so there shouldn't be much dust in about ½ year. Perhaps the cooling just sucks and combined with that high-ish room temperature of yours, it can't keep the CPU cooler than that.

Yeah, I'm keeping the temperature within it's range by power limit throttling at 17w. (Even though it's a 15w cpu, I adjusted it to 17w.)

According to ARK*, it's a 25W CPU, configurable down to 10W. But does it throttle when it gets hot?

Your temps are completely fine. My laptop runs much, much, hotter.

This is a hot CPU. Your CPU is not hot.

My CPU was pulling 80.556 watts while gaming. It will pull 95 watts in a heavy cpu-load like cinebench 20 where the GPU isn't also engaged. Laptops just can't keep CPU's cool when they use that much power, but a 17 watt ULV cpu is way easier to keep cool.

No, the 25W is just the configurable up.

That's the actual TDP (if i'm correct)

Also it does thermal throttling when it reaches 95C or higher.

Thanks but I'm a bit worried if the temperatures might kill my cpu slowly as when I'm doing a long gaming session.

 

[Fizban]

Those temps aren't going to kill a CPU. It throttles at 95 C and not 80 C for a reason, 80 C is perfectly safe, even for extended periods of time.

Ah, my bad, that's true. But like said above, 80C isn't dangerous to the CPU. Personally I wouldn't be worried if it's just around 80C'ish, for a laptop that isn't that bad. My i5-4210M (2c/4t) runs somewhat hotter (even after cleaning and repasting, I use MX-4 too) and that doesn't bother me.

So will it still live long just like the other laptops? Mostly they're within 5 years right?

Most likely the laptop would die from some other reason than the CPU cooking itself to death. Actually I've never heard that a laptop CPU would died because of overheating.

Fair enough. Also, another random question. Does desk affect the laptop's heat? Since laptops are sucking up air around it.

Agree!
Broken charger, bad battery, user dropping the laptop, broken screen, liquid spill... But CPU Cooking itself, I think only old HP's DV2000 overheating on BGA sockets. They are kind known here by the overheat with AMD processors, long ago around 2004-2006

Basically no if the desk is clean (so it doesn't drain dust and other crap from it). A hot metallic table etc. would probably heat it up.

My Laptop Specs are i7-4710mq 12gb ram, 2g gt840m
i haven't check my 2014 laptop temps, but i have replaced the thermal paste in it with arctic silver.
Before just playing hearthstone the fan spins up quite loud, now it spins quietly.
In slightly more demanding titles like fallout3, resident evil 2 remake - the pc still runs relatively cool.
Doing office work and browsing the fan doesn't spin at all.

What i do is i circulate fresh air from outside so that the laptop can get fresh cool area rather in an enclosed room.
Its summer now where i currently live and its hot.

I owned a Toshiba Qosmio with a GTX 770M several years ago that cooked itself, but that was the only laptop I have owned (and I've owned many) that actually "really" had bad overheating issues. In general laptops run much hotter than desktops, but they're expected to do so, and are safely able to do so.

My current laptop concerns me a bit, but I think even it's safe. I'm just not sure it should exist. I feel like my i7-10875H only exists because Intel felt threatened by AMD, and felt like they needed to release a powerful 8-core/16-thread CPU to remain competitive, despite 14 nm technology not really being good enough to warrant it. The 6-core i7's all run reasonably cool, it's only the 8-core laptop cpus made by Intel that I find to run alarmingly hot.

I think my desk one of the problem too. It's interface is like metallic or something but heats up easily.

Those temps looks good tbh. My laptop has Athlon gold processor and the temps are more or less same as yours also with 28c ambient temp. Short of using those laptop cooling pad that shoots up the air to the bottom of your laptop, I couldn't think anything else. Though not really recomend that since it will make the laptop freaking dusty.

How well does a laptop cooling pad work? We Amazon'd one ourselves to find out

Temperatures will definitely go down, but we want to find out by just how much and if the increase in fan noise would be worth the trade-off. With 4.5 stars and over 11,000 reviews on Amazon, we have our expectations set quite high.

Could be, can you try it on other surface that would it affect the temps?

There's little to no differences. I guess I'll just put it back.
