Applied new thermal and CPU is overheating

Hello everyone, new here and thought I ask a question.

I just applied a new thermal paste or my laptop processor/ gpu/ cpu. Arctic Silver 5 + ArcticClean, a 2 Process cleaning solution that came with it.

After I cleaned, and applied new thermal my GPU temp went down from 55C or 45-49C during peak usage. However, my CPU is still overheating, sometimes I am just sitting here and it gets so hot it turns off.

I live in a extremely hot area, but I have a cooling pad under the laptop that I bought for 50bucks, it does wonders. & Also have a fan blowing air into the air vent where it sucks in air. This doesn't seem to help that much since it still overheats.

Anything I can do to cool down the CPU?

I've checked out all power options and they seem to adjust only the GPU temp.

Was it overheating before you applied the thermal paste?

^ This

I would also check your heatsink to see if there's any dust build up... I remember taking apart a friends laptop earlier this year and my goodness....HOLY MOTHER OF DUST BUNNIES is all I can say to describe :lol: 

Temps went down by around 10-15C afterwards on her i3 :)

It was. Even with new thermal, the temperature never changed by THAT much. :/  It is painful to see my laptop just skyrocketing in temperature.

Dust bunnies is probably your answer then ;)

Two things I can think of since you've done everything that can be reasonably expected:

Confirm that the internal cooling fan is really spinning all the time that it needs to be. A failing fan may stop/start/stop on its own.

Check the BIOS for the thermal shutdown temperature. Confirm that your setting matches the recommended for your model of laptop.

Hope you get it solved.

^ Another plausible factor giving OP headaches.

However, I would really like OP to give a look at his heatsink. More than likely, that is the issue as he said he experienced overheating problems even before replacing the thermal compound.

So! I went about and REPLIED the thermal paste

This time!

I cleaned everything again with the ArcticCleaner, both surfaces and sprayed everything with dustoff... making sure no bunnies.

Just put back my laptop and BOOM, the temperature for all dropped by 5-7 DEGREES! :D 

So I am guessing it could had been bunnies!

Now I am at 50C and less for all.

Thanks guys for the responses!
