Left fan stuck at high speed

crwdns2934249:0crwdne2934249:0:

I spilled a little water on the keyboard and immediately dried it out. The laptop functioned perfectly fine after. I was worried that there could be some water deep inside so, a couple days later, I removed the logic board to clean underneath it. There was not any water there. I used canned air to clean out dust, and a hairdryer to make sure there was no water. After reassembling, the left fan has been stuck at full speed whenever the computer is running. I did not remove the fan during this cleaning.

I am using iStat Menus. The thermal sensors appear to be fine.

I am able to use iStat Menus to set the fan speed for the right fan but the left does not respond to the controls.

I tried resetting the SMC and PRAM. I ran an Apple Diagnostics and it said there may be a problem with the fan. I installed a replacement fan and the problem still persists.

What can I do to get the fan under control? Could the heat from the hair dryer have damaged the fan connector or its circuit?
