Well done. It is so satisfying to take care of something yourself instead of turning it over to someone else to fix for you. I've pulled apart 4-5 laptops over the years to replace everything from the hinges that broke in a fall, to the trackpad, to hard drives. I wish they made some of the components (like that fan) more accessible for home repair. But they really don't want you to repair them, they want you to decide the laptop is dead and buy a new one.
