Is laptop heat paste old on it and new on it is that bad?

Is laptop heat paste old on it and new on it is that bad?

Well, let's put it this way.

Completely wrong.

Old paste down, new on it.

Can something bad happen my laptop hangs something

Because I don't have alcohol so I can remove the old one

Yes, it can overheat.

No you don't need alcohol. Just take a Zewa, that's enough.

Yes, yes.

Temperatures will be significantly worse than before.

But it is already on I should take it off again what can happen in the worst case

Mostly works without it if it is not too dry.
Otherwise other cleaning agents, glass cleaners, (cleaning) gasoline, spirit (is alcohol etc.)
Silicon is very insensitive to chemicals.

In the worst case, the computer crashes regularly.

Where can I look it up?

More paste doesn't automatically mean more cooling. Thermal paste can conduct heat better than air, but that's why it is far from being a good heat conductor. Too much paste is rather insulating. However, too much is very difficult to accomplish because the excess simply swells out of the side and the mainboard is soaked.

BUT! > If you have just left the old, partially or completely dried paste on it, these crumbs can ensure that the cooler can't sit properly and the resulting gaps worsen the heat transport.

With a program.

HWmonitor is my favorite.

Then you should run a stress test. E.g. For the CPU prime 95, for the gpu furmark. Ideally both at the same time.

Yes, take it off again.

And you can even get dry WLP with Zewa.

Is not dry but is time-consuming because I have to dismantle my entire PC

I'll make it clear which one is normal

Under full load in prime 95, the CPU should be below 90 ° C for a laptop, preferably less with a desktop.

But depends on the cpu. AMD cpus prefer to run a bit cooler than that from intel.
Higher temperatures can be expected with a laptop.

How long should I let that go

Since the app always says less than 80%, that's good

Yes, you learn from mistakes. Not much helps. WLP is applied very thinly.

It is worse if your CPU keeps saying goodbye.

Where?

80% what?

Well, you let prime 95 run until the temperature no longer rises. How long that is depends on the cooling solution.

Installed the other one

You need prime 95, furmark and HWmonitor. (or alternative)

The programs show a lot. 80% what?

CPU

I'm more interested in the temperature than the load.

But, you have to use the CPU first
