Question Overheating laptop

[ILI-BIG]

Hi everyone. I recently upgraded my laptop's CPU T6400 to X9100. But it overheats. It reaches 95⁰C at gaming. I m using 1.63w/m-k thermal paste. I found Thermal Grizzly Kryonaut for laptop. Will it cool down?

I doubt that thermal grease can make any significant difference.

I see many complaints about gaming laptops not performing well.
Usually gaming while plugged in.
One common cause is thermal throttling.
Laptop coolers must, of necessity be small and light.
The coolers are also relatively underpowered.
If you run an app such as HWMonitor or HWinfo, you will get the current, minimum, and maximum cpu temperatures.
For intel processors, if you see a max of 100c. it means you have throttled.
The cpu will lower it's multiplier and power draw to protect itself
until the situation reverses.
At a lower multiplier, your cpu usage may well be at 100%
What can you do?
First, see that your cooler airways are clear and that the cooler fan is spinning.
Use a windows balanced power profile, not the performance profile.
Set a minimum cpu performance to something like 20%

It is counter-intuitive, but, try changing the windows balanced power profile advanced functions to a max of 90% instead of the default of 100%
You may not notice the reduced cpu performance.

The biggest issue I'm seeing is you upgraded the CPU to a much higher power one. Unless the laptop configuration came with the option of using it, the cooler is likely insufficient.

In any case I don't recommend Kryonaut for laptop applications because:

• Kryonaut degrades at 80C
• It's a thinner paste and the mounting pressure on laptop CPU coolers is lower than in desktops, so it has a better chance of pumping out (i.e., you'll have to repaste sooner than you'd like)

Which thermal paste should i use? My thermal paste is disgustingly bad. My previous CPU had reached above 85⁰C at gaming.

Either Noctua NH-2, Arctic MX-4/5, or Thermal Grizzly Hydronaut.

However I'm still suspicious your laptop can actually handle a 45W CPU. It was likely designed only for 33W CPUs.

Either Noctua NH-2, Arctic MX-4/5, or Thermal Grizzly Hydronaut.

Can i use Arctic MX-6? Is it better than MX-4?

As noted several times above, choice of thermal paste is unlikely to make a significant difference.
