[SOLVED] CPU fan noisy and temperature spike up after cleaning *HELP*

Hey guys, I had a gaming laptop MSI GL63 for quite some time and uses it almost everyday so recently, I have decided to clean my laptop's air vents and fans from dust or other dirt that has accumulated over time. It was a throughout cleaning including removing both fans and the heatsink. I noticed that there are thermal paste on the CPU and thermal pad underneath the heatsink, since I don't have the compound (to reapply a new layer) so I just place everything back on.

But once I turned on the laptop, the fans seem to be spinning faster and louder than usual. It does not make any weird noises but seems that it is spinning faster from the way it sounds. I am very sure that the fans is way more quieter before. So, I decided to check the CPU temperature and to my surprise the reading of the CPU temperature is in constant value between 90 ° c to 94 ° c . I am sure that it is not an ideal temperature for a laptop on idle state. I tried to increase both fan speed in the hope of reducing the temperature but to no avail.

What did I do wrong? I want to play games but afraid that it might increase the CPU temperature and eventually damage it even more.

You must ALWAYS reapply thermal paste if you remove the heatsink.

That is the problem. It is NOT safe to run. You must buy paste, clean off the old paste from both the heatsink, and the chip itself with 91% ispropyl alcohol. Then reapply past onto the areas that had the paste on them (plenty of videos on youtube on how much to use) and then reinstall the heatsinks and fans.
