Chosen Solution

Hi all! I recently replaced the thermal paste on my MBP 15” Retina Mid-2015, and my temps are looking much better, but my fans are still running full speed! Any thoughts about why this is happening? Photos from Monity and Macs Fan Control attached below!

I know this is a dumb thing to add; but, did you clean out the fans while you were inside the MacBook. Or did you tamper with a temperature sensor?
