MacBook Pro very slow and fans always full speed

I opened and cleaned my MacBook pro 2020 device, after cleaning the logic board and fans with a soft brush, my computer slowed down incredibly when I closed the lid, it is not possible to move the mause cursor and the fans are always running at full speed, what problem could have happened?

It does sound like you damaged something within the logic board. I’ve seen a few cases of people inserting the slim-Jim a bit to deep hitting the logic board components. Did you follow this guide MacBook Pro 13" Four Thunderbolt Ports 2020 Lower Case Replacement?

Carefully pop the bottom case off again and compare the images here MacBook Pro 13" (A2251, 2020) 2.3 GHz Logic Board with Paired Touch ID Sensor. Focus on the sides. Take some tight pictures of the area that looks damaged, post them here so we can see so we can guide you on what’s next.

I brought my computer to a service and, trying to open the back cover, I plucked the microchip shown with zoom in the picture😓 they told me it was something like a thermal controller, does this chip have any name?
