Q: My 2009 MBP started to get very hot over the last few months and trying to clean the fans did not get me much cooler during usage. I do have the 1189 battery in my unit but it doesn't seem to be MY problem because I have removed it and use AC.
My MBP is getting very hot. Followed the procedure to clean the fans, still hot. Opened the Activity Monitor and "quit" any functions using the CPU, still hot. Now I am strictly running on AC, removed my 1189 battery, still have heat issues, any thoughts out there?

Overheating can be a software issue too. Please see this Apple article:
Apps can affect Mac performance, battery runtime, temperature, and fan activity - Apple Support
That article's Step 1 is very important to getting an accurate result.
You will get the cleanest resluts by quitting all applications you opened before doign the test, but don't do the test right after a restart--it may not find the culprits. Use the computer normally for 4-6 hours and then do the test.
Also let Activity monitor run from at least a minute. As processees swap in and out, some miscreants can hide if you make a decision after viewing only a few seconds of results.
