What did you do on the hard drive? Was it changed? Check to see if the temperature sensor is fully seated into the logic board. (Either will cause run away fan issues.

Did you remove the battery or replace it?

I didn't touch SSD just disconnected from logic. I haven't touched battery. Stranglly after cleaning Mac is running noticeably slower ( lower fps in games) ??

But again Mac is running 10 C cooler with the same settings.

Of course it is running cooler the fans are at full speed. Check to see that the sensors are correctly and fully plugged in.

they were on full speed before cleaning
