Mac running slow and fan running at high speed after water spill
I recently spilled water on my computer and did not remove the bottom casing, much less the battery, as I now know I should have.
I am able to start the computer and get to my desktop however at start up the fan immediately begins and the computer loads VERY slowly.
Once completely booted, the same continues. I have turned off all "at start up" settings for all apps.
Here are the stats for my computer from iStatPro and SmartUtility:

Since the computer is not able to run unless hooked up to the charger, I am aware I need to purchase a new battery. My next step is figuring out where I need to start in regards to RAM (I think this is where the issue lies in slowness) and the fans (I'm stumped on this one).
Any and all help would be absolutely wonderful.
Thank you in advance!

Update
Thanks for the suggestions! It was definitely water that was spilled on the computer. Promise. :) I will be cracking this bad boy open this morning to see what going on. Bc it was water, I'm guessing, as Mayer said, there won't be residue but I will definitely take a good look and let you guys know what I find.
Update
after opening the casing there is visible residue on the motherboard. i will be proceeding to clean per ABCellars.
Update
cleaned motherboard and still having issues with slow speeds and constant fan. will be testing RAM.
Update
i tested RAM and still no good. I am in the middle of AHT. I'm thinking there may be an issue with a heat sensor which is kicking up kernel_task CPU usage.
Update
I have reset PRAM and SMC to no avail. I ran the AHT and got the following code:
4SNS/1/C0000008:TN1D--124
What does this mean?
I have a kernel_task that is eating up CPU usage (over 170%) with over 60 threads. I have reset the heatsink with thermal paste and made sure all things were connected appropriately on the logicboard.
I have also purchased a new battery to replace the old in case that had an effect on performance and there is still no change.
HELP???
Update
After replacing the motherboard and seeing no improvement in computer performance, I replaced the airport card. There seems to be some issue with my airport card connection. After completely disconnecting the airport card connection and reverting to using a wifi usb dongle for internet connection, I have had no more kernel panics. While this is only a temporary fix to the problem, I have a running computer that is now kernel panic free and fully functional/portable.
