Removed and re-attached CPU heatsink with new thermal paste, but CPU performance is really bad..

Since I've cleaned out my PC, I can't play games at a reasonable FPS. My CPU usage spikes to 100%, I rarely saw that before unless I had like 6 applications running at once. Is my CPU fried, or what is causing my issues?

Do I need to run my PC for a while before it will run OK?

Thermal Paste used is Arctic Silver 5

I did not use a vaccum to clear out dust
Specs:

Windows 10

ASUS Z170-P Motherboard

Intel Core i5-6500 3,2 MHz Processor

NVIDIA GEFORCE GTX 1060 6gb Video Card

    Also the part about curing time:

    Important Reminder:
    Due to the unique shape and sizes of the particles in Arctic Silver 5's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.

    So by my estimation of this statement it would take almost a year of normal use to properly cure the AC5 compound, or almost nine days of continuous power cycles to meet their recommendation.

    Yeah, I read that, thanks. I found that the CPU was actually working as intended, but my GPU was not being detected. I solved it by re-plugging the GPU. I'm dumb lol.

    But thanks for trying to help
