Liquid damage, Now running slow with overactive fan.

Had a water bottle next to my bed and accidentally knocked it over in the middle of the night onto my mac.

The following day I opened it up, my track-pad was over-responsive, wifi didn’t work at the time either. Wifi and trackpad are working again since I let it air out. However, the slow processing speed has not changed.

There was some corrosion noted near the track pad connecter/cable on one side, otherwise there was no other obvious signs.

The fan is over-working also present on start up.

Can anyone point me towards some resources? I am a novice with Mac repairs, however am comfortable replacing my own display for my iphone if this helps with my skill level.
